Product Description
The QUADLOG safety PLC provides a safer, more reliable control solution for potentially dangerous
applications (e.g. burner management, emergency shutdown, fire and gas detection systems). Traditional
choices for a safety system include mechanical relays, a programmable logic controller (PLC), or a triple
modular redundant (TMR) system. As with many choices, each of the options comes with its advantages
and disadvantages. QUADLOG has been designed to provide the optimal mix of each option’s strengths,
essentially providing a safety PLC.
Historically, safety systems consisted of mechanical relays. These systems provide high safety; however,
they come with significant maintenance demands and lack the communication capabilities,
self-diagnostics, configuration flexibility, and calculation tools needed in today’s highly automated plants.
Due to the limitations posed by relays, programmable logic controllers (PLCs) have been replacing them
as the most commonly used safety system. As safety and availability become more critical, a conventional
PLC will not provide adequate protection. A major concern with a conventional PLC is the potential for a
dangerous failure. This is because a PLC only provides one solid state circuit path. An input circuit
receives a signal from a sensor, the main processor solves logic functions and performs calculations
required to generate an output, and the output circuit typically energizes or de-energizes a solid-state
switch (TRIAC or FET) to control an actuator. A component in this circuit could fail in a way that
energizes the output switch. In this state, the controller cannot de-energize the output and perform its
protection function, and the condition is not likely to be detected by diagnostics. This type of failure could
lead to a condition threatening to both equipment and personnel.

Introduction
CGQL-4
To remedy this problem, QUADLOG incorporates two circuit paths. QUADLOG’s standard “dual”
architecture provides Protected Outputs™. Output energy flows through diverse technology dual
switches. A solid state switch provides the normal controller output. A relay, controlled by built-in
diagnostics, supplies the second switch through a set of normally-open contacts. If a dangerous failure is
detected within the output channel, the relay contacts can be opened, de-energizing the output to ensure a
safe failure.
This standard “dual” QUADLOG architecture features a single controller; single I/O with Protected
Outputs and “fail on” and “fail off” diagnostic output options; redundant power supplies; redundant
communication links with CRC checking and watchdog timers; redundant, diverse watchdog timers; CPU
instruction tests and exhaustive RAM tests; and program flow control checks. The standard architecture
can also be expanded to include optional redundant control modules, providing a low-cost option for
redundancy of critical functions.
QUADLOG incorporates a modular design for flexible control of plant operations. The QUADLOG
modules are rack-mounted, DIN-sized intelligent (microprocessor-based) modules designed to perform a
specific application function, such as control or I/O. They are selected individually and combined to
accommodate a process application. Each QUADLOG system typically consists of a control module and
a complement of I/O modules.
Connection between the individual QUADLOG modules is provided by three busses:
MODULBUS
Used by control, communications and computer modules to share process and system
information.
IOBUS
Provides a control module with dedicated, secure access to field I/O points which
terminate at I/O modules.
POWER BUS
A triple-redundant bus providing power to QUADLOG modules.
The QUADLOG I/O modules are a series of configurable modules acting as interfaces between control
modules and field termination signals, offering a broad range of analog, discrete, and special condition
I/O points. All QUADLOG I/O modules are configured using the 4-mation configuration software.
During configuration, 4-mation is used to define the channel type and several parameters that vary
according to channel type. After a configuration is created, it is loaded into the I/O module’s memory,
and a copy of the configuration is stored in the controller’s non-volatile memory. This allows on-line
removal and replacement of the module without the need for reconfiguration.
1.2
Software Compatability
QUADLOG System Software Version 3.30 is compatible with the 4-mation versions listed in Table 1-1
and the QUADLOG module ROMs listed in Table 1-2. QUADLOG System Software Version 3.30 is
compatible with all QUADLOG CCMs (Critical Control Modules) and Advanced Control Module Plus
(ACM+) model QLACM12BBN. QUADLOG System Software Version 3.30 requires QUADLOG I/O
modules to have 3.x version ROMs.

Softlist Parameters:
Shutdown_Channel: When TRUE and channel quality is BAD or QUESTIONABLE, the CAI reports a
shutdown error. The configuration can be changed to only shut down the affected inputs or not to shut
down at all. Only channels that are critical to the process should be configured as shutdown_channels.
Note that in rack-to-rack redundant systems, a switchover to the verify side, rather than a system
shutdown, occurs if an I/O failure occurs. Both sides of a redundant system would have to fail for a
shutdown to occur.
InputFaultState: When the input channel is faulted (BAD, QUESTIONABLE, or UNAVAILABLE
data quality), the channel reports the value configured in this softlist parameter. No_Change returns the
actual value. MinRange returns the smallest value (MinScale). MaxRange returns the largest value
(MaxScale).
MinScale: The module will linearly scale raw data (4-20 mA) to engineering units for each channel. The
scaling algorithm uses the MinScale/MaxScale parameters set by the user. For example, given a
MinScale of 0.0 and a MaxScale of 100.0. If the input to the channel is 12mA, the scaled value will be
50.0. MinScale can be any REAL number (REAL numbers are valid between -3.4028E38 and
+3.4028E38)
MaxScale: MaxScale can be any REAL number.
EngUnits: Engineering units for the scaled value can be selected from a list of common engineering
units.
Bias: The user can enter a bias in engineering units on a per channel basis to compensate for known
offsets. The bias value is added to the scaled input.
OpenCircuitTest: The user can enable or disable open circuit testing. An open circuit condition exists if
the reading is <= 3.6mA.

XTC_CriticalXMTR: When this parameter is TRUE, the Model 345 XTC Critical Transmitter limits
will be used for over/under range, open/short circuit, and transducer failure indications, as defined in
Table 2-3. When this parameter is FALSE, the over/under range is extended to include the transmitter
failure range, so transmitter failure is not reported. This parameter should be set to FALSE for noncritical transmitters.

InputFaultState: When the input channel is faulted (BAD, QUESTIONABLE, or UNAVAILABLE
data quality), the channel reports the value configured in this softlist parameter. No_Change returns the
actual value. MinRange returns the smallest value (MinScale). MaxRange returns the largest value
(MaxScale).
MinScale: The module will linearly scale raw data (4-20 mA) to engineering units for each channel. The
scaling algorithm uses the MinScale/MaxScale parameters set by the user. For example, given a
MinScale of 0.0 and a MaxScale of 100.0. If the input to the channel is 12mA, the scaled value will be
50.0. MinScale can be any REAL number (REAL numbers are valid between -3.4028E38 and
+3.4028E38)
MaxScale: MaxScale can be any REAL number.
EngUnits: Engineering units for the scaled value can be selected from a list of common engineering
units.
Bias: The user can enter a bias, in engineering units, on a per channel basis to compensate for known
offsets. The bias value is added to the scaled input.
OpenCircuitLimit: This parameter is a REAL value that establishes the upper boundary, in milliamps,
for the open circuit diagnostic. The adjustment range is 0.0 mA to 4.0 mA and the default value is set to
3.6 mA to comply with the NAMUR NE-43 standard. Setting the open circuit value to 0.0 mA disables
the open circuit diagnostic. If you disable the diagnostic for a safety critical channel, you will have to
configure logic in the controller to detect and respond to an open circuit fault condition.
UnderRangeLimit: This parameter a REAL value that establishes the upper boundary for the underrange diagnostic, in milliamps. The adjustment range is 0.0 mA to 4.0 mA. Setting this value equal to, or
beyond, the open circuit limit disables this diagnostic. The lower boundary of this diagnostic is equal to
the open circuit limit value. By default, this value limit is set to the open circuit limit default value (3.6
mA) so this diagnostic is disabled.
OverRangeLimit: This parameter a REAL value that establishes the lower boundary of the over-range
diagnostic, in milliamps. The adjustment range is from 20.0 mA to 22.0 mA. Setting this value equal to,
or beyond, the short circuit limit disables this diagnostic. The upper boundary of this diagnostic is equal
to the short circuit limit value. By default, this value is set to the short circuit limit default value (21 mA),
so this diagnostic is disabled.
ShortCirLimit: This parameter a REAL value that establishes the lower boundary, in milliamps, for the
short circuit diagnostic. The adjustment range is 20.0 mA to 22.0 mA and the default value is set to 21.0
mA to comply with the NAMUR NE-43 standard. The default value prevents most over-range values
from reporting an error while still allowing true short circuits to be detected. The default value permits a
defective (open) sense resistor on the CAI Marshalled Termination Assembly (MTA) to be detected.
Open circuit and short circuit diagnostics provide coverage for some fault modes in wiring and I/O
devices that are not covered by other diagnostics. These are conditions that may be a result of a failed
component on the I/O module, masking the actual sensor data.. If these diagnostics are disabled for safety
critical channels, another way to detect the fault modes may be required. This can be accomplished with
configuration logic within the controller. If handled by the control logic, this logic must be configured to

drive the process into a safe state upon failure. Alternatively, there may be ways to monitor the I/O
devices and I/O signals independently.
If the channel is a non-redundant shutdown_channel (i.e., it is safety critical and not 1oo2 or 2oo3), the
open circuit and short circuit detection must be enabled at some reasonable thresholds where they will be
detected.
If the open circuit diagnostics are totally disabled, function blocks such as the Less Than (LT) block or
the Analog Voter (ANVOTER) block can be used to detect specific limits (or ranges) on the input values.
The compare limits for these blocks should detect input values near 0 mA (e.g. between 0 - 0.5 mA).
These block outputs can be combined with maintenance logic or timing logic to determine if a true fault
needs annunciation.
When programming the diagnostics for this channel type, note the following considerations listed in
Table 2-5.

Critical Discrete Supervised Input Channel
The CDSI (Critical Discrete Supervised Input) channel type returns an analog variable, automatically
ranged and scaled to 0-20 mA, which may be converted to discrete values by the Critical Discrete
Supervised Input (CDSI) function block. When this channel type is selected, it should be connected to
the CDSI function block in the controller logic. This function block contains the fixed thresholds that
convert the analog signal from the CAM to a boolean value. Refer to Standard Function Blocks for
QUADLOG (document number CGQL-7) and the CDSI block for detailed information. Also refer to the
QUADLOG Critical Analog Input Module (CAI) Installation and Service Instruction (document number
SDQLCAI-1) for information on CDSI channel type wiring details. Table 2-6 lists the softlist parameter

Critical Analog Module (CAM)
The CAM can interface 32 channels of analog I/O and discrete input signals to a control module’s
IOBUS. To isolate field faults, all channels are electrically isolated from the module’s CPU, IOBUS, and
ground. Also, each channel uses an isolated 28 V power source, and all channels are current-limited to
protect against short-circuits.

Critical Analog Module (CAM)
Shutdown_Channel: When TRUE and channel quality is BAD or QUESTIONABLE, the CAM reports
a shutdown error (Class 4, SSC 37, EC 31). Based on the default configuration supplied with
QUADLOG, a class 4 error causes all outputs to shut down to their de-energized state (i.e. 0 volts or 0
mA). The configuration can be changed to only shut down the affected outputs or not to shut down at all.
Only channels that are critical to the process should be configured as shutdown_channels. Note that in
rack-to-rack redundant systems, a switchover to the verify side, rather than a system shutdown, occurs if
an I/O failure occurs. Both sides of a redundant system would have to fail for a shutdown to occur. Refer
to the Safety Manual for QUADLOG Version 3.30 or Higher (document number CGQLSAFETY-2) for
details of the shutdown configuration logic.
Enabling this parameter also enables the controller readback diagnostic. This diagnostic compares the
output value sent by the controller to the value "read back" by the CAM.
MinScale: The module performs a linear conversion from engineering units to the selected OuputRange
for each channel. The scaling algorithm uses the MinScale/MaxScale and OutputRange parameters that
you set. For example, given a MinScale of 0.0, a MaxScale of 100.0, and an OutputRange of 4-20 mA, if
the value written to the CAM Analog Out channel is 50, the module will output 12 mA. MinScale can be
any REAL number (REAL numbers are valid between -3.4028E38 and +3.4028E38).
MaxScale: MaxScale can be any REAL number.
OutputRange: CAM Analog Output channels are configurable to operate with two current ranges:
4-20 mA and 0-20 mA
EngUnits: Engineering units for the scaled value can be selected from a list of common engineering
units.
ProtectedOutput: Each output can be configured to turn off (0 mA = -25%) all CAM I/Os in the event
that diagnostics determine that the output current is greater than it is intended to be by 2% or more. You
may want to configure an output as a ProtectedOutput if it is critical to the process, or if it presents a
possible hazard to personnel or equipment.
Bias: The user can enter a bias (in engineering units) on a per channel basis to compensate for known
offsets. The bias value is added to the scaled output.
ReadBack: The state of an output channel is automatically "read back" by input circuitry on the same
channel. ReadBack is used to diagnose and report faults. You can disable ReadBack, which, in turn,
disables reporting of readback-related faults (i.e. Calculate Readback Data Mismatch, Verify & Calculate
Readback Mismatch, Verify Readback Data Mismatch, Partner Readback Data Mismatch).

Shutdown_Channel: When TRUE and channel quality is BAD or QUESTIONABLE, the CAM reports
a shutdown error (Class 4, SSC 37, EC 31). Based on the default configuration supplied with
QUADLOG, a class 4 error causes all outputs to shut down to their de-energized state (i.e. 0 volts or 0
mA). The configuration can be changed to only shut down the affected outputs or not to shut down at all.
Only channels that are critical to the process should be configured as shutdown_channels. Note that in
rack-to-rack redundant systems, a switchover to the verify side, rather than a system shutdown, occurs if
an I/O failure occurs. Both sides of a redundant system would have to fail for a shutdown to occur. Refer

AC Critical Discrete Input Module (CDI_AC)
The CDI_AC module interfaces discrete 115 Vac input signals with a control module’s IOBUS,
supporting 24 isolated AC inputs. This enables AC inputs from different power sources to be connected
to the same module. Furthermore, each channel is electrically isolated from the module’s CPU, IOBUS,
and ground.
Event recording inputs and outputs are high-speed channels used in conjunction with the functions blocks
of the Sequence of Events Recorder Function Block Library for detecting, monitoring, controlling, and
recording discrete state changes (i.e. events). This data is collected by a Sequence of Events (SOE)compatible module, such as the CDI, that is capable of high-speed event gathering. Events are stored to
an array of strings. The data can then be viewed through the Sequence of Events Viewer, a utility
program. Refer to Sequence of Events Viewer Operator’s Guide (document number OG39SOE-2) for

Critical Discrete Module (CDM)
Critical Discrete Module (CDM)
The Critical Discrete Module (CDM) interfaces discrete DC sensors and actuators with a control
module’s IOBUS. It provides 32 channels. Each channel can be configured as any of the five discrete
channel types: an input, an output, an event recording input, an event recording output, or a pulse output.
The CDM’s inputs are current sinking (i.e. the input device is wired between the power supply positive
and the I/O terminal). Outputs are current sourced (i.e. the output device is wired between the output
terminal and power supply common). In addition, a soft-fuse circuit protects each output channel from a
short-circuit in the field wiring and prevents a short from affecting other CDM channels. Note that a softfuse can be reset locally or remotely.
Event recording inputs and outputs are high-speed channels used in conjunction with the function blocks
of the Sequence of Events Recorder Function Block Library for detecting, monitoring, controlling, and
recording discrete state changes (i.e. events). This data is collected by a Sequence of Events (SOE)compatible module, such as the CDM, that is capable of high-speed event gathering. Events are stored to
an array of strings. The data can then be viewed through the Sequence of Events Viewer, a utility
program. Refer to Sequence of Events Viewer Operator's Guide (document number OG39SOE-2) for
information on using this utility.
All channel types, except pulse output, can be configured to run pulse test diagnostics to ensure the
channel is in working order. The diagnostics require inputs to have an external device called a SafetyRelated Switch Adapter (SRSA). The diagnostics detect shorts in the field, channel-to-channel shorts, and
channel-to-power shorts.
IMPORTANT
To avoid signal interference, do not externally wire an output channel to
other QUADLOG or APACS input channels if it is configured to use
pulse test diagnostics. The short pulses emitted by the diagnostics are
not intended to be connected directly to these input types.
Starting with version 3.1 of the CDM software (firmware), each output channel can be configured so the
diagnostics can also detect an open load condition (i.e. when there is no load attached to that channel’s
I/O termination). When an open load condition is detected, the module reports a module error (SSC 07,
EC 37). The following table lists the criteria necessary to determine if the load connected to an output
channel is compatible with the open load diagnostics. It applies to both redundant and non-redundant
CDM configurations.

Critical Discrete Module (CDM)
CGQL-4
TABLE NOTES:
1. A load resistance value in the range between the open and connected thresholds can be detected as either
open or connected.
2. If an output channel is connected to a load, but the module still reports an error (SSC 07, EC37), you can
disable the open load diagnostics by setting the channel’s PulseDiagTest softlist value to disable.
However, this parameter must be enabled for a safety critical output channel. Starting with firmware
3.02, the OpenCircuitTest softlist parameter disables open load diagnostics.
A discrete pulse output channel type is configurable so it is on for a time duration that you define (within
a range of 25 to 2000 ms and a resolution of 25 ms).
Every input and output circuit is electrically isolated from the CDM's CPU, IOBUS, and ground. In
addition, a soft-fuse circuit protects each output channel from a short circuit in the field wiring and
prevents a short from affecting other CDM channels. Note that a soft-fuse can be reset locally or
remotely.

output for a pre-determined time period (the resolution of the pulse output is ±25 ms, accurate to within
±2 ms). The time period is established by the Duration softlist parameter value. It can be set between 25
ms and 2000 ms.
When the BOOL output value, sent from the control module [e.g. Critical Control Module (CCM)] to the
CDM, transitions from FALSE to TRUE, the corresponding output will turn on for the specified duration.
However, if another FALSE to TRUE transition occurs before the end of the pulse, the pulse output is
retriggered. Therefore, to keep a pulse output channel constantly on, you must write a FALSE to TRUE
transition to the channel at a faster rate than the pulse duration.
The following timing diagram shows the output value being sent from a CCM to the CDM. In this
example, the CCM scan rate is set to 50 ms; therefore, the CCM can only change the state of the output
every 50ms. The CDM output is configured as a Discrete Pulse Output channel with a duration of 150
ms. Figure 4-1 shows how a FALSE to TRUE transition of the CCM output triggers a pulse output. It
also illustrates that once a pulse output has been triggered, it can be retriggered before the end of the pulse
duration. Table 4-7 lists the softlist parameters for the CDM Discrete Output Pulse channel type.

Duration: The duration of a pulse output channel can be specified between 25 ms and 2000 ms in 25 ms
increments. Any value not in 25 ms increments is rounded up to the next 25 ms increment, however,
there is a 5 ms deadband before rounding occurs. For example, if the duration specified is 28 ms, the
actual pulse will be 25ms because of the deadband. Likewise, if the duration specified is 31 ms, the actual
pulse will be rounded up to 50 ms. Use the examples in Table 5-8 as a guideline.

Readback: The state of an output channel is automatically “readback” by input circuitry on the same
channel. The Readback is used to diagnose and report the following five types of faults. Disabling
Readback disables reporting of the first four types.

5.
Diagnostic Read Error
Output Failed ON (energized)
Protected Output Failed ON (energized)
Output Failed OFF (de-energized, blown hard fuse)
Output Failed OFF (de-energized, tripped soft-fuse)
NOTES
Disabling ReadBack does not disable the controller readback diagnostic.
ReadBack should be enabled if Shutdown_Channel = TRUE.
As listed above, there are two possibilities for an output channel to fail
off. One way is when the hard fuse blows (it is not field replaceable); the
other is when the soft-fuse trips (it is locally or remotely resettable). The
soft-fuse trip error cannot be disabled by the softlist.
ProtectedOutput: Each output can be configured to turn off all CDM outputs in the event that a channel
is intended to be off but diagnostics have determined that it is on. You may want to configure an output as
ProtectedOutput if it is critical to the process, or if it presents a possible hazard to personnel or equipment.
Shutdown_Channel: When the Shutdown_Channel parameter is set to TRUE, a shutdown error (class 4,
SSC 37, EC 31) is reported in addition to a class 2 or class 3 channel error that affects channel quality
(when BAD or QUESTIONABLE quality is set). When this parameter is FALSE, the shutdown error is
not reported. Based on the default configuration supplied with QUADLOG, a class 4 error causes all
outputs to shut down to their de-energized state (i.e. 0 volts or 0 mA). The configuration can be changed
to only shut down the affected outputs or not to shut down at all. Only channels that are critical to the
process should be configured as shutdown_channels. Note that in rack-to-rack redundant systems, a
switchover to the verify side, rather than a system shutdown, occurs if an I/O failure occurs. Both sides of
a redundant system would have to fail for a shutdown to occur. Refer to the Safety Manual for
QUADLOG Version 3.30 or Higher (document number CGQLSAFETY-2), section 6.7 (Shutdown
Logic), for details of the shutdown configuration logic.
Enabling this parameter also enables the controller readback diagnostic. This diagnostic compares the
output value sent by the controller to the value “read back” by the CDM.

Critical Discrete Output (CDO) Modules
The Critical Discrete Output (CDO) modules include the AC Critical Discrete Output (CDO-AC) module
and the DC Critical Discrete Output (CDO-DC) module.
Event recording inputs and outputs are high-speed channels used in conjunction with the functions blocks
of the Sequence of Events Recorder Function Block Library for detecting, monitoring, controlling, and
recording discrete state changes (i.e. events). This data is collected by a Sequence of Events (SOE)compatible module, such as the CDO, that is capable of high-speed event gathering. Events are stored to
an array of strings. The data can then be viewed through the Sequence of Events Viewer, a utility
program. Refer to Sequence of Events Viewer Operator’s Guide (document number OG39SOE-2) for
information on using this utility.

Softlist Parameters
Shutdown_Channel: When TRUE and channel quality is BAD or QUESTIONABLE, the CDI reports a
shutdown error (Class 4, SSC 37, EC 31). Based on the default configuration supplied with QUADLOG,
a class 4 error causes all system outputs to shut down to their de-energized state (i.e. 0 volts or 0 mA).
The configuration can be changed to only shut down the affected outputs or not to shut down at all. Only
channels that are critical to the process should be configured as shutdown_channels. Note that in rack-torack redundant systems, a switchover to the verify side, rather than a system shutdown, occurs if an I/O
failure occurs. Both sides of a redundant system would have to fail for a shutdown to occur. Refer to the
Shutdown Logic section of the QUADLOG Safety Manual forVersion 3.30 or Higher (document number
CGQLSAFETY-2) for details about shutdown configuration logic.
IOBUS Fault: If the CDO module is unable to communicate with the controller (loss of IOBUS), the
output is set to the IOBUS Fault state. Once set to the IOBUS Fault, the diagnostic must be
acknowledged for normal output updates to occur again.
Protected Output: When Protected Output is set to Enable, the module will de-energize the output via
the diagnostic cutoff switch if diagnostics detect that the output is ON when it is supposed to be OFF.
Open Circuit Test: This enables a diagnostic which determines whether a load is present. Note that
loads of less than 50 mA may not be reported correctly by this diagnostic.
Readback: The CDO contains circuitry on every output to “read back” the actual output current.
Readback is used to diagnose the following faults (see APS for list of Readback diagnostics). Disabling
Readback inhibits reporting of Readback-related diagnostics.
PulseTestDiag: Enables pulse diagnostic testing for this channel.
SOE Recording: Enables SOE recording for this channel.

Description: This parameter is valid if SOE Recording is enabled. It is a description, up to 28 characters,
of the channel that is monitored to be configured by the Sequence of Events Recorder block. The
description is formatted as a STRING data type. It is inserted as a substring within the EVENTS string of
the Sequence of Events Recorder block.
Event Priority: This parameter is valid if SOE Recording is enabled. This data is used for establishing
an event’s priority. You can set a channel’s priority from 1 (highest) to 4 (lowest). This priority value can
then be used to sort events, such as when they are being formatted for viewing. This priority value is
inserted within the EVENTS string of the Sequence of Events Recorder block.
Alarm State: This read-only parameter is used to establish the alarm and/or trip state of the channel. If
the channel type is De-Energize-to-Trip, the alarm state is by definition FALSE. If the channel type is
Energize-to-Trip, the alarm state is TRUE. This parameter is not configurable.

MinScale: The module will linearly scale raw data (mA) to engineering units for each channel. The
scaling algorithm uses the MinScale/MaxScale and InputRange parameters set by the user. For example,
given a MinScale of 0.0, a MaxScale of 100.0, and an InputRange of 4-20 mA, if the input to the channel
is 12 mA, the scaled value will be 50.0.

Threshold: You can select the threshold for voltage input pulses. The Regular threshold is 2.5 V with
130 mV of hysteresis. The TTL threshold is 1.4 V with 130 mV of hysteresis.
MinRange: The MinRange parameter allows you to specify a minimum operating value in Hz. If the
reading drops below this value, an underrange error is reported.
MaxRange: The MaxRange parameter allows you to specify a maximum operating value in Hz. If the
reading goes above this value, an overrange error is reported.
MinScale: The module will linearly scale raw data (Hz) to engineering units for each channel. The
scaling algorithm uses the MinScale/MaxScale and MinRange/MaxRange parameters values that you set.
For example, given a MinScale of 0.0, a MaxScale of 100.0, a MinRange of 0, and a MaxRange of
10,000. If the input to the channel is 5000 Hz, the scaled value will be 50.0.

MaxScale: MaxScale can be any REAL number.
EngUnits: Engineering units for the scaled value can be selected from a list of common engineering
units.
Resolution: The EAM counts the number of pulses occurring in a measured length of time. The
frequency of the waveform is calculated by dividing the number of pulses by the corresponding length of
time. Increasing the resolution increases the length of time in which pulses are accumulated.
To meet certain application requirements, the selection of 10-bit resolution actually yields 11-bit
resolution. This provides better than 0.06% accuracy with a minimal delay.
Shutdown_Channel: When TRUE and channel quality is BAD or QUESTIONABLE, the EAM disables
(0V or 0 mA) all of its output channels and reports a shutdown error (class 4, SSC 37, EC 31). Based on
the default configuration supplied with QUADLOG, a class 4 error causes all outputs to shut down to
their de-energized state (i.e. 0 volts or 0 mA). The configuration can be changed to only shut down the
affected outputs or not to shut down at all. Only channels that are critical to the process should be
configured as shutdown_channels. Note that in rack-to-rack redundant systems, a switchover to the verify
side, rather than a system shutdown, occurs if an I/O failure occurs. Both sides of a redundant system
would have to fail for a shutdown to occur. Refer to the Safety Manual for QUADLOG Version 3.30 or

MinRange: MinRange is an optional parameter that allows you to specify a minimum operating
value in EngUnits. If the reading drops below this value, an underrange error is reported.
MaxRange: MaxRange is an optional parameter that allows you to specify a maximum
operating value in EngUnits. If the reading goes above this value, an overrange error is reported.
MinScale: The module will linearly scale raw data (ohms) to engineering units for each channel.
The scaling algorithm uses the MinScale/MaxScale and MinRange/MaxRange parameters that
you set. For example, given a MinScale of 0.0, a MaxScale of 100.0, a MinRange of 0.0, and a
MaxRange of 1000, if the input to the channel is 500 ohms, the scaled value will be 50.0.
MinScale can be any REAL number (REAL numbers are valid between -3.4028E38 and
+3.4028E38).

MaxScale: MaxScale can be any REAL number.
EngUnits: Engineering units for the scaled value can be selected from a list of common
engineering units.
Bias: You can enter a bias in engineering units, on a per channel basis, to compensate for known
offsets. The bias value is added to the linearized input.
Input_Fault_State: If channel quality is bad or questionable, you can select to have the module
return the actual reading (No_Change), the largest value for the channel (Maxscale), or the
smallest value (Minscale). The default is to return the actual reading.
DigFiltTimeCnst: Digital filtering can be applied to resistance input channel signals to reduce
the effects of electrical noise. The digital filter is a first order lag, adjustable for time constants of
0.0159 to 159.0 seconds. Equivalent breakpoint frequencies are 10.0 to 0.001 Hz. The default
value can be increased for noisy signals.
StepResponseTime: This parameter determines the time for the channel to fully respond to a step input.
A longer StepResponseTime provides more accurate readings. The valid range is between 0.1 and 40.00
seconds.

Standard Analog Module (SAM)
11.0 Standard Analog Module (SAM)
The Standard Analog Module (SAM) can interface both analog and discrete I/O signals to a control
module’s IOBUS. It provides 32 channels, each of which can be configured for standard I/O types.
Related signals, such as the I/O for a particular loop, can be grouped together. To isolate field faults, each
channel is electrically isolated from the module’s CPU, IOBUS, and ground. Also, each channel uses an
isolated 24 V power source, and all channels are current-limited to protect against short circuits.
11.1 SAM Module Scope Parameter
Table 11-1 shows the Module Scope softlist parameter for the SAM. To view/edit the module scope
parameters, place the cursor on the desired module in the module tree and select the Edit, Object/Item
menu item. The Hardware Modules dialog box opens. Choose the Softlist command button to open the
Module Scope Softlist dialog box.

OpenCircuitTest: You can enable or disable open circuit testing. An open circuit condition exists if the

Shutdown_Channel: When TRUE and channel quality is BAD or QUESTIONABLE, the SAM module
disables (0 mA) all of its I/O and reports a shutdown error (Class 4, SSC 37, EC 31). Based on the
default configuration supplied with QUADLOG, a class 4 error causes all outputs to shut down to their
de-energized state (i.e. 0 volts or 0 mA). The configuration can be changed to only shut down the
affected outputs or not to shut down at all. Only channels that are critical to the process should be
configured as shutdown_channels. Note that in rack-to-rack redundant systems, a switchover to the verify
side, rather than a system shutdown, occurs if an I/O failure occurs. Both sides of a redundant system
would have to fail for a shutdown to occur. Refer to the Safety Manual for QUADLOG Version 3.30 or

Standard Discrete Module Plus (SDM+)
12.0 Standard Discrete Module Plus (SDM+)
The Standard Discrete Module Plus (SDM+) interfaces discrete DC sensors and actuators with a control
module’s IOBUS. It provides 32 channels. Each channel can be configured to any of five discrete
channel types: an input, an output, an event recording input, an event recording output, or a pulse output.
The SDM+’s inputs are current sinking (i.e. the input device is wired between the power supply positive
(+) and the I/O terminal). Outputs are current sourced (i.e. the output device is wired between the output
terminal and the power supply common). A pulsed output is an output channel which is on for a userdefined duration (within the range of 25 to 2000 ms and a resolution of 25 ms).
Event recording inputs and outputs are high speed channels used in conjunction with the function blocks
of the Sequence of Events Recorder Function Block Library for detecting, monitoring, controlling, and
recording discrete state changes (i.e. events). This data is collected by a Sequence of Events (SOE)compatible module, such as the SDM+, that is capable of high speed event gathering. Events are stored to
an array of strings. The data can then be viewed through the Sequence of Events Viewer, a PC Utility
program. Refer to the Sequence of Events Viewer (document number SG39SOE-2) for information on
using this utility.
Each input and output circuit is electrically isolated from the module’s CPU, IOBUS, and ground. In
addition, a soft-fuse (TM) circuit protects each output channel from a short circuit in the field wiring and
prevents a short from affecting other SDM+ channels. Note that a soft-fuse can be reset locally or
remotely.

NOTE
As listed on the previous page, there are two possibilities for an output
channel to fail off. One way is when the hard-fuse blows (it is not field
replaceable), the other is when the soft-fuse trips (it is locally or remotely
resettable). The soft-fuse trip error cannot be disabled by the softlist.
Shutdown_Channel: When TRUE and channel quality is BAD or QUESTIONABLE, the SDM+ module
disables (0 mA) all of its output channels and reports a shutdown error (Class 4, SSC 37, EC 31). Based
on the default configuration supplied with QUADLOG, a class 4 error causes all outputs to shut down to
their de-energized state (i.e. 0 volts or 0 mA). The configuration can be changed to only shut down the
affected outputs or not to shut down at all. Only channels that are critical to the process should be
configured as shutdown_channels. Note that in rack-to-rack redundant systems, a switchover to the verify
side, rather than a system shutdown, occurs if an I/O failure occurs. Both sides of a redundant system
would have to fail for a shutdown to occur. Refer to the Safety Manual for QUADLOG Version 3.30 or
Higher (document number CGQLSAFETY-2), section 6.7 (Shutdown Logic), for details of the shutdown
configuration logic.
Description: This is a description, up to 28 characters, of the channel that is configured to be monitored
by the Sequence of Events Recorder block. The description is formatted as a STRING data type. It is
inserted as a substring within the EVENTS string of the Sequence of Events Recorder block.
EventPriority: This data is used for establishing an event's priority. You are to set a channel's priority
from 1 (highest) to 4 (lowest). This priority value can then be used to sort events, as when they are being
formatted for viewing. This priority value is inserted within the EVENTS string of the Sequence of
Events Recorder block.
AlarmState: This parameter is used to establish the alarm state of the channel. You can choose which
state, TRUE or FALSE, represents an alarm condition. For example, if you set this parameter to TRUE,
the channel is said to be in alarm when the channel's value toggles from FALSE to TRUE. This also
inserts an "A" (Alarm) character in the last character position in the EVENTS string of the Sequence of
Events Recorder block. Otherwise, it is an "N" character (No alarm).
PulseDiagTest: This softlist parameter is not used in this module. It is listed here because this channel
type is shared with other modules.
12.2.4 Disc Pulse Out Channel
The Disc Pulse Out channel type accepts a BOOL variable.
The Disc Pulse Out channel type is triggered by a BOOL variable. This channel type turns on its assigned
output for a pre-determined time period (the resolution of the pulse output is ±25 ms, accurate to within
±2 ms). The time period is established by the Duration softlist parameter value. It can be set between 25
ms and 2000 ms.
When the BOOL output value sent from the control module to the SDM+ module transitions from
FALSE to TRUE, the corresponding output turns on for the specified duration. However, if another
FALSE to TRUE transition occurs before the end of the pulse, the pulse is retriggered. Therefore, to keep

a pulse output channel constantly on, you must write a FALSE to TRUE transition to the channel at a
faster rate than the pulse duration.
The following timing diagram shows the output value being sent from a CCM to the SDM+. In this
example the CCM scan rate is set to 50 ms, therefore, the CCM can only change the state of the output
every 50ms. The SDM+ output is configured as a pulse output channel with a duration of 150 ms. Figure
11-1 shows how a FALSE to TRUE transition of the CCM output triggers a pulse output. It also
illustrates that once a pulse output has been triggered, it can be retriggered before the end of the pulse
duration. Table 12-6 lists the softlist parameters for the SDM+ Discrete Output Pulse channel type.

Duration: The duration of a pulse output channel can be specified between 25 ms and 2000 ms in 25 ms
increments. Any Duration softlist parameter value not in 25 ms increments is rounded up to the next 25
ms increment, however, there is a 5 ms deadband before rounding occurs. For example, if the duration
specified is 29 ms, the actual pulse will be 25ms long because of the deadband. Likewise, if the duration
specified is 31 ms, the actual pulse will be rounded up to 50ms long. Use the examples in Table 11-7 as a
guideline.

Readback: The state of an output channel is automatically “readback” by input circuitry on the same
channel. The readback is used to diagnose and report faults. There are five types of faults as listed here.
You can disable readback, which, in turn, disables reporting of the first four types.

NOTE
As listed above, there are two possibilities for an output channel to fail
off. One way is when the hard-fuse blows (it is not field replaceable); the
other is when the soft-fuse trips (it is locally or remotely resettable). The
soft-fuse trip error cannot be disabled by the softlist.
ProtectedOutput: Each output can be configured to turn off all outputs in the event that a channel is
intended to be off but diagnostics have determined that it is on. You may want to configure an output as
ProtectedOutput if it is critical to the process or if it presents a possible hazard to personnel or equipment.
Shutdown_Channel: When TRUE and channel quality is BAD or QUESTIONABLE, the SDM+ module
disables (0 mA) all of its output channels and reports a shutdown error (Class 4, SSC 37, EC 31). Based
on the default configuration supplied with QUADLOG, a class 4 error causes all outputs to shut down to
their de-energized state (i.e. 0 volts or 0 mA). The configuration can be changed to only shut down the
affected outputs or not to shut down at all. Only channels that are critical to the process should be
configured as shutdown_channels. Note that in rack-to-rack redundant systems, a switchover to the verify
side, rather than a system shutdown, occurs if an I/O failure occurs. Both sides of a redundant system
would have to fail for a shutdown to occur. Refer to the Safety Manual for QUADLOG Version 3.30 or

Voltage Input Module (VIM)
13.0 Voltage Input Module (VIM)
The Voltage Input Module (VIM) interfaces thermocouple and voltage input signals to a control module’s
IOBUS. It provides 16 channels, each of which can be configured to be a thermocouple or voltage input.
The VIM can accommodate many input types with minimal configuration and high accuracy. Each input
is electrically isolated from the module’s CPU, IOBUS, and ground to isolate field faults. In addition,
each channel is isolated from other channels.
13.1 VIM Module Scope Parameters
Table 13-1 lists the Module Scope softlist parameters for the VIM. To view/edit the module scope
parameters, place the cursor on the desired module in the module tree and select the Edit, Object/Item
menu item. The Hardware Modules dialog box opens. Choose the Softlist command button to open the
Module Scope Softlist dialog box.

ScanRate: This is a read-only parameter that displays the current scan rate of the module. Generally, the
scan rate will be the same as the scan rate of the control module, but can be a multiple of the control
module's scan rate.
LineFreq: The module software utilizes a notch filter to reduce noise from AC power sources.
Specifying the line frequency of AC power will optimize the filtering algorithm.
SharedTC: This parameter only applies when using VIMs in a redundant system. Often, one
thermocouple is wired to both the calculate (primary) and verify (backup) VIMs. If this is the wiring
arrangement for the VIMs being configured, set SharedTC to Yes. If each VIM has its own
thermocouples, set SharedTC to No. For non-redundant VIMs, set SharedTC to No (default).
13.2 VIM Channel Types
The channel types supported for the VIM are listed here. For information on configuring I/O channels,
refer to the “Configuring I/O Channels” section of Using the ProcessSuite 4-mation Configuration
Software (document number CG39-20).

DigFiltTimeCnst: Digital filtering can be applied to thermocouple input signals to reduce the
effects of electrical noise. The digital filter is a first order lag, adjustable for time constants of
0.0159 to 159.0 seconds. Equivalent breakpoint frequencies are 10.0 to 0.001 Hz. The default
value can be increased for noisy signals.
StepResponseTime: This parameter determines the time for the channel to fully respond to a step
input. A longer StepResponseTime will provide higher resolution and better repeatability of the
signal.

InputRange: Voltage input channels are able to read any voltage between -10 and +10. The
module utilizes auto-ranging circuitry to provide high resolution even at millivolt levels. For
scaling and diagnostic purposes, the range of values being measured by the channel must be
specified. Several standard ranges are selectable from a list, or, a custom range can be selected

by specifying Custom for the InputRange and editing Custom_Range_Low and
Custom_Range_High values.
Custom_Range_Low: An optional parameter that allows you to specify a minimum input range
in volts. If the reading drops below this value, an underrange error is reported. This parameter is
only used when InputRange is specified as Custom.
Custom_Range_High: An optional parameter that allows you to specify a maximum input
range in volts. If the reading goes above this value, an underrange error is reported. This
parameter is only used when InputRange is specified as Custom.
MinScale: The module will linearly scale raw data (volts) to engineering units for each channel.
The scaling algorithm uses the MinScale/MaxScale parameter values that you set. For example,
given a MinScale of 0.0, a MaxScale of 100.0, and an InputRange of 1-5 Volts, if the input to the
channel is 3 Volts, the scaled value will be 50.0. MinScale can be any REAL number (REAL
numbers are valid between -3.4028E38 and +3.4028E38).
MaxScale: MaxScale can be any REAL number.
EngUnits: Engineering units for the scaled value can be selected from a list of common
engineering units.
DigFiltTimeCnst: This parameter sets the time constant of a low-pass digital filter applied to the
input data. This filter reduces non-repetitive noise from the input data and can be disabled by
setting this parameter to 0.0.
StepResponseTime: This parameter sets the length of a moving-average digital filter applied to the input
data. It determines the time to fully respond to an input step. Increasing this parameter reduces periodic
or repetitive noise and improves repeatability and resolution. The recommended setting for this
parameter is between 0.5 and 4.0 seconds.
