CS1W-PTS/PDC/PTW/PTR/PPS/PMV

CS-series Process Analog I/O Units
CS1W-PTS/PDC/PTW/PTR/PPS/PMV
CSM_CS1W-PROCESS_DS_E_2_1
Provides the functionality of
isolators, power supplies, signal
converters, and other devices.
• The Analog Input Unit converts analog input signals
such as 1 to 5 V or 4 to 20 mA into digital values, and
takes the values scaled in industrial units, and
transfers it to the CPU Unit as the process value.
Because of this, no ladder program is required at the
CPU Unit for scaling.
• The Analog Output Unit converts analog output set
values from the CPU Unit to analog output signals
CS1W-PDC55
CS1W-PTS55
CS1W-PTS56
such as 4 to 20 mA or 1 to 5 V, and outputs them.
• The built-in functions, such as measurement value
alarms, rate-of-change calculations, and square roots, have enabled major savings in cost and space compared
with previous systems.
• High-resolution Models and 8-point Input Models are also available. By combining the Units, logging/monitoring
systems can be constructed, or the Units can be used together with LCBs/LCUs to construct complete process
control systems.
• Parameters can be easily displayed and set in an easy-to-understand form without special tools.
Features
Process Analog Input:
• Up to eight analog inputs can be connected for each Unit.
• There is isolation between input channels, so unwanted circuit paths between thermocouple inputs can be prevented. (Except for CS1W-PTR01/
02)
• Output scaling (±32,000)
• Process value alarms (HH, H, L, LL)
• Input disconnection alarm
• Rate-of-change calculation and alarm
• Top/bottom/valley hold (CS1W-PTS11/PTS12/PDC11 only)
Process Analog Output:
• Up to four analog set values can be output for each Unit.
• All outputs are isolated.
• Output rate-of-change limit
• Output high/low limits
• Output scaling (±32,000)
• Control output answer input (CS1W-PMV01 only)
Isolated-type Pulse Input:
• Provides up to four pulses from a device such as a displacement flowmeter. The accumulated value can also be calculated at the same time
and transferred to the CPU Unit at each cycle. (CS1W-PPS01)

CS1W-PTS/PDC/PTW/PTR/PPS/PMV
System Configuration
These Process Analog I/O Units belong to the CS-series Special I/O Unit group.
• They can be mounted to CS-series CPU Racks or Expansion I/O Racks.
• They cannot be mounted to C200H CPU Racks, Expansion I/O Racks, or SYSMAC BUS Remote I/O Slave Racks.
The number of Units that can be mounted to one Rack (either a CPU Rack or Expansion I/O Rack) depends upon the maximum current supplied
by the Power Supply Unit and the current consumption by the other Units.
There are no restrictions on Rack position.
Note: I/O addresses for Special I/O Units are allocated according to the unit number set on the switches on the front panel, and not according to
the slot position in which they are mounted.

Temperature sensor types
Thermocouple B, E, J, K, N, R, S, T or
−80 to 80 mV. (Set separately for each of four inputs.)
Input ranges
The input range can be set within any of the measurable
input ranges shown in Table 1 (below).
Note: Internally, inputs are processed in five ranges (refer
to Table 2 below), so accuracy and resolution
accord with these internal ranges.
Scaling in industrial units
Data to be stored in the allocated words in the CIO area
must be scaled (with the minimum and maximum values
set). Data can be stored at 0% to 100%.
Data storage in the CIO Area
The value derived from carrying out the following processing in order of the actual process data in the input range is
stored in four digits hexadecimal (binary values) in the allocated words in the CIO Area.
1) Mean value processing → 2) Scaling → 3) Zero/span adjustment → 4) Output limits
Sensor type, input range, and scaling to industrial units are
separate for each of the 4 inputs.
Note: Sensor type, input range, and scaling to industrial
units are set in the DM Area.
Example:
Thermocouple: K; input range: 0 to 500°C; industrial unit
scaling: 0 to 500°C. DM Area settings are as follows:
Thermocouple: 3 (0003 hex)
Input signal maximum: 5000 (1388 hex)
Input signal minimum: 0 (0000 hex)
Industrial unit maximum value stored: 500 (01F4 hex)

Sensor Types and Input Ranges
The temperature sensor (thermocouple) type and input range are set in the allocated words in the DM Area for every four inputs. The input range
can be set anywhere within the measurable input ranges shown in Table 1.

Therefore, the accuracy and resolution are determined by the ratio of the selected internal range (0 to 4) span to the set input range span
(electromotive force converted value). For the internal range, a larger number is selected when both the minimum and maximum values of the
range fall within that next range.
For example, suppose that the thermocouple type is K and the set input range is 0 to 800°C. The electromotive force for K 0 to 800°C is 0 to 33.277
mV. Since both the minimum and maximum values fall within the limits for internal range No. 1 (−40 to 40 mV), that range will be selected.
The following table shows the set input ranges corresponding to the internal range numbers 0 to 4.

Note: With Thermocouple Input Units, process values can be scaled in industrial units for the set input range. It is possible to set the process value
scaling higher than the resolution, but it will cause the values to be unstable.

Note: 1. Cold junction sensors are installed between A2 and A3, and between A8 and A9 when the product is shipped. Do not remove them when
using the Unit. If they are removed, temperatures cannot be measured correctly because there will be no compensation.
2. Use the same cold junction sensors that come with the Unit, and leave them just as they are. They are provided specifically for this Unit
and its circuitry, and temperatures cannot be measured correctly if they are switched around or if another Unit's sensors are used in their
place.
3. For unused input terminals, short-circuit the positive and negative sides (e.g., terminals A4 and B4 for input No. 1) of the thermocouple
inputs with the lead wire.
4. When connecting input No. 4, remove the cold junction sensor between CJ2+ and CJ2−, and then reconnect it after the input is
connected. Attempting to connect the input without removing the cold junction sensor may result in damage to the sensor.

The sensor type, input range, and scaling can be set individually for each of 4 inputs, which are each selectable from
B, E, J, K, L, N, R, S, T, U, WRe5-26, PL II, and mV.
Scaling
Data to be stored in the allocated words in the CIO area must be scaled (individually for each of the 4 inputs, with the
minimum and maximum values set). Data can be stored at 0% to 100%.
Data storage in the CIO Area
The value derived from carrying out the following processing in order of the actual process data in the input range is
stored in four digits hexadecimal (binary values) in the allocated words in the CIO Area.
1) Mean value processing → 2) Scaling → 3) Zero/span adjustment → 4) Output limits

Note: The method for calculating the error in temperature measurements, including the temperature coefficient, is given below. The "full scale of
electromotive force" is the difference between the high limit and low limit converted to electromotive force for each thermocouple.
Example
Ambient temperature: 30 °C
Temperature Sensor: K thermocouple (−270 to 1,372 °C)
Measured temperature:500 °C
From electromotive force table
−270 °C:
−6.458 mV
1,372 °C:
54.86 mV
Full scale: 61.344
Electromotive conversion of temperature coefficient:
61.344 mV × ±0.01%/°C = ±6.13 μV/°C
Error in electromotive force at 30°C:
±6.13 μV/°C × (30°C − 25°C) = 30.65 μV/°C
Temperature difference between measurement point and terminals on Unit (ambient temperature) (based on ambient temperature of 30 °C and
Measured temperature of 500 °C):
470 °C
Electromotive force per °C at a measured temperature of 470 °C (from the electromotive force tables for a K thermocouple):
43 μV/°C
Error in temperature coefficient: ±30.65 μV ÷ 43 μV/°C = ±0.7°C
Error in measured temperature = Accuracy ± Error from temperature coefficient + Error in cold junction compensation = ±0.8°C + ±0.7°C +
±1.0°C = ±2.5°C
Sensor Type and Input Range
The Temperature Sensor type and input range are set in the allocated words in the DM Area for every four inputs. The input range can be set
anywhere within the measurable input ranges shown in the following table. Accuracy and resolution, however, are not determined from the set
input range, but rather from the measurable input range shown in the following table. Therefore, accuracy and resolution do not change even when
a narrow input range is set.

Note: 1. If the indication range is exceeded, a sensor error will occur and the sensor error bit will turn ON. The process value will be clamped at
the lower or upper limit of the indication range, depending on the setting for data direction at sensor error.
2. The lower limit for B thermocouples is 0°C/°F.
3. The indicator range for BCD display will be clamped at the lower (or upper) limit in the region between the lower (or upper) limit of the
setting range and the point where a sensor error occurs.
For 0.1°C/0.1°F indication with minus sign indicated by leftmost 4 bits (bits 12 to 15): Lower limit = −99.9, Upper limit = 999.9.
For 0.1°C/0.1°F indication with minus sign indicated by leftmost bit (bit 15): Lower limit = −799.9, Upper limit = 799.9.

Note: Action for Unused Input Terminals
• Short-circuit the positive (+) and negative (−) sides of the thermocouple input section using a lead wire. For example, short terminals A3
and A2 for No. 1 thermocouple input.
• Cold junction sensors are mounted before shipment. If one of the cold junction sensors is disconnected, cold junction compensation will
stop and correct measurement of temperatures cannot be made. Always make sure the cold junction sensors are connected when using
the Units.
• Cold junction sensors are calibrated separately for each Unit and connected circuit, so correct temperatures will not be measured if a cold
junction sensor from another Unit is used or if the two cold junction sensors in a Unit are swapped. Use the cold junction sensors as they
are provided, without making any changes.
• Do not connect anything to NC terminals. Do not use NC terminals as relay terminals.
• Always ground the GR terminal on the Power Supply Unit of the PLC.
• If the input device uses a voltage generator, temperature compensator, or similar device, then ground the input device if it has a ground
terminal.

Input ranges
The input range can be set within any of the measurable
input ranges shown in Table 1 (below).
Note: Internally, inputs are processed in five ranges
(refer to Table 2 below), so accuracy and
resolution accord with these internal ranges.
Scaling in industrial units
Data to be stored in the allocated words in the CIO area
must be scaled (individually for each of 4 inputs, with the
minimum and maximum values set). Data can be stored
at 0% to 100%.
Data storage in the CIO Area
The value derived from carrying out the following processing in order of the actual process data in the input range is
stored in four digits hexadecimal (binary values) in the allocated words in the CIO Area.
1) Mean value processing → 2) Scaling → 3) Zero/span adjustment → 4) Output limits
Sensor type, input range, and scaling to industrial units
are separate for each of the 4 inputs.
Note: Sensor type, input range, and scaling to industrial
units are set in the DM Area.
Example:
Sensor type: Pt100; input range: 0 to 500°C; industrial
unit scaling: 0.0 to 500°C. DM Area settings are as
follows:
Sensor type: 0 (0000 hex)

Sensor Type and Input Range
The resistance thermometer type and input range are set in the allocated words in the DM Area for every four inputs. The input range can be set
anywhere within the measurable input ranges shown in Table 1.

Therefore, the accuracy and resolution are determined by the ratio of the selected internal range (0 to 4) span to the set input range span. For the
internal range, a larger number is selected when both the minimum and maximum values of the range fall within that next range.
For example, suppose that the sensor type is Pt100 and the set input range is −100 to 400°C. Since both the minimum and maximum values fall
within the limits for internal range No. 1 (−200 to 438°C), that range will be selected.
Note: With Resistance Thermometer Input Units, process values can be scaled (e.g., 0% to 100%) in industrial units for the set input range. It is
possible to set the process value scaling higher than the resolution, but it will cause the values to be unstable.

Input ranges
The input range can be set within a range of –50 to 150°C
(variable setting).
Note: Internally, inputs are processed in the above
range (refer to Table 2 below), so accuracy and
resolution accord with this internal range.
Scaling in industrial units
Data to be stored in the allocated words in the CIO area
must be scaled (with the minimum and maximum values
set). Data can be stored at 0% to 100%.
Data storage in the CIO Area
The value derived from carrying out the following processing in order of the actual process data in the input range is
stored in four digits hexadecimal (binary values) in the allocated words in the CIO Area.
1) Mean value processing → 2) Scaling → 3) Zero/span adjustment → 4) Output limits
Input range and scaling to industrial units are separate for
each of the 4 inputs.
Note: Sensor type, input range, and scaling to industrial
units are set in the DM Area.
Example:
Input range: −50 to 100°C; industrial unit scaling: −50.0 to
100.0°C. DM Area settings are as follows:

Note: • Wire the same length to A, B, and b, so that the impedance will be the same. In particular, do not short circuit between B and b at the
terminal block.
• For unused input terminals, connect approximately 100 Ω between the platinum-resistance thermometer input terminals A and B and short
terminals B and b with a lead wire. If resistance is not connected between terminals A and B and terminals B and b are shorted or if
terminals A and B and terminals B and b are left open, the alarm output will turn ON and the ALM indicator will light.
• Do not connect anything to NC terminals. Do not use NC terminals as relay terminals.
• Always ground the GR terminal on the Power Supply Unit of the PLC.
• If the input device uses a voltage generator, temperature compensator, or similar device, then ground the input device if it has a ground
terminal.

CS1W-PTS/PDC/PTW/PTR/PPS/PMV
Accuracy and Resolution for ±10 V User-set Range
With the ±10-V user-set range, the input signal zero and span can be set anywhere within the range −10.000 to 10.000 V. Internally, however,
inputs are processed in five progressive ranges (numbers 0 to 4), as shown in the following table.
Table 1: Internal Ranges
Internal range number
Measurable voltage
Internal range span
0
−10.000 to 10.000 V
20.000 V
1
−5.000 to 5.000 V
10.000 V
2

3
−1.250 to 1.250 V
2.500 V
4
−0.625 to 0.625 V
1.250 V
Therefore, the accuracy and resolution of the set range span are determined by the ratio of the internal range (0 to 4) span to the set input range
span. For the internal range, a larger number is selected when both the minimum and maximum values of the range fall within that next range.
For example, suppose that the set input range is 0.000 to 3.000 V. Since both the minimum and maximum values fall within the limits for internal
range No. 1 (−5.000 to 5.000 V), that range will be selected.

Accuracy and Resolution in ±10-V User-set Range
The ±10-V user-set range allows the input signal's input range to be set to any range within −10.000 V to 10.000 V. Accuracy and resolution,
however, are not determined by the input range, but rather by the measurable input range (−10.000 V to 10.000 V). Therefore, accuracy and
resolution do not change even if a narrow input range is set.

to instantaneous values (pulses x pulse weight / time unit). Any of the following can be selected
as the time unit: 1 s, 3 s, 10 s, 30 s, or 60 s. (The time unit is set in the DM Area.)
Note: 1. Errors and fluctuations will increase when the input signal pulse rate is low, so specify
a longer time unit.
2. The instantaneous value is only refreshed at intervals of the time unit set. Therefore,
when the Unit is restarted, the instantaneous value will be 0000 until the time set as
the time unit has elapsed.
3. When pulse weight conversion is used for accumulated values, the number of pulses
obtained by multiplying the actual number of input pulses by the pulse weight (0.1000
to 3.2000) for one time unit is used.
Instantaneous value
scaling
This function can be used for scaling
instantaneous values (pulses × pulse weight/time
unit), i.e., setting data with respect to a maximum
value, and storing them in the allocated words of
the CIO Area.
• When instantaneous value (pulses × pulse
weight/time unit) is 100% input:
Can be set from 0.001 pulses/time unit to
32,000 pulses/time unit.
• Maximum value for Instantaneous value scaling
(industrial units):
Scaling of the above instantaneous value
(100% input) is possible from
−32,000 to 32,000 (8300 to FFFF, 0000 to 7D00
hex).
Note: When pulse weight conversion is used for
accumulated values, scaling is already
performed for each pulse, so an exponent
of 10 of the industrial unit is set in the
instantaneous value (pulses × pulse
weight per time unit) for a 100% input.
Data storage in the
CIO Area
The value derived from carrying out the following
processing in order of the instantaneous value
(pulses x pulse weight/time unit) is stored in four
digits hexadecimal (binary values) in the allocated
words in the CIO Area.
1) Mean value processing → 2) Instantaneous
value scaling → 3) Scaling → 4) Zero/span
adjustment → 5) Output limits
Example 1:
To obtain a pulse input of 0 to 2,000 pulses/
s for a flow of 0 to 300.0 ml/s:
Time unit: 1 s
Instantaneous value 100% input: 2,000
Maximum value for instantaneous value
scaling (industrial units): 3,000
Example 2:
When pulse inputs at 0 to 2,000 pulses/s are
obtained for a flowrate of 0 to 300.0 ml/s,
and the pulse weight function is used for
totaling:
There are 0.15 ml per pulse, so the pulse
weight = 0.15.
For a flowrate of 0 to 300.0 ml/s, 0 to 2,000
× 0.15 = 300 pulses/s. Therefore,
Time unit: 1 s
Instantaneous value 100% input: 300
Maximum value for instantaneous value
scaling (industrial units): 3,000
Mean value
Calculates the moving average for the specified number of past instantaneous values (1 to 16),
processing (input filter) and stores that value in the CIO Area as the instantaneous value.
Function
Instantaneous value
alarm
Instantaneous value 4-point alarm (HH, H, L, LL), hysteresis, and ON-delay timer (0 to 60 s) are
available.
Pulse weight
conversion
Performs scaling for a single pulse.
Use for the accumulated value when the pulse weight (weight/pulse) is a fraction (not an
exponent of 10). (See note.)
The pulse weight (0.1 to 3.2) is multiplied by the actual number of pulses input. This number of
pulses is used as the input for conversion to instantaneous values (pulses × pulse weight per
time unit) and the input for totaling prior to stepdown.
Example: When the pulse weight from the flowmeter is 0.26 ml/pulse, the pulse weight is set to
0.26. When one pulse (0.26 ml) is input, it is treated as a 0.26 pulse, and when two pulses (0.52
ml) are input, they are treated as a 0.52 pulse.
The weight per pulse becomes 1 ml, so to calculate in the CPU Unit the simple (unscaled) value
in industrial units (ml) based on the accumulated value from the Pulse Input Unit (value in words
n+5 to n+8), the value can be calculated simply using 1 ml/pulse.
Note: When the accumulated value from the Pulse Input Unit in the CPU Unit is not used (i.e.,
when only the instantaneous value is used), pulse weight conversion is not required. Use
instantaneousness value scaling to convert to industrial units.
Accumulated value
The accumulated number of pulses (0 to 9,999 pulses) for each input is stored in the allocated
words of the CIO Area. When 9,999 is exceeded, the value returns to 0 and starts counting
again.
Note: When pulse weight conversion is used, the accumulated value for the number of pulses
obtained by multiplying the actual number of input pulses by the pulse weight (0.1000 to
3.2000) is used.
Stepdown
When the accumulated value is used, this function prevents accumulated value overflow by
reducing the number of input pulses. The actual number of input pulses is multiplied by one of
four factors (×1, ×0.1, ×0.01, or ×0.001), and the number of input pulses accumulated is then
based on that value.
Note: This stepdown function operates only for accumulated values, and not for instantaneous
values. When the pulse weight conversion function is used, it uses for the number of
pulses obtained by multiplying the actual number of input pulses by the pulse weight
(0.1000 to 3.2000).

Outputs can be refreshed by means of IORF(097) in the ladder diagram program.
Note: Regardless of the CPU Unit's operation mode (including Program Mode), the analog output value in the allocated words of the CIO Area is
always output refreshed. As shown in the above table, however, when the operation mode is changed to Program Mode, the analog output
value in the CIO Area is either cleared or held depending on the status of the CPU Unit's I/O Memory Hold Flag (A500.12). In particular, be
careful when this flag is ON, because the value prior to the mode change will be held and that value will be output refreshed.

The output value in the CIO Area is held at the value prior
to the operation mode change, and that is output
refreshed.
Fatal error or CPU standby after
turning ON the power supply
0 V is output.
Special I/O Unit cyclic refresh
disabled
Outputs can be refreshed by means of IORF(097) in the ladder diagram program.
Note: Regardless of the CPU Unit's operation mode (including Program Mode), the analog output value in the allocated words of the CIO Area is
always output refreshed. As shown in the above table, however, when the operation mode is changed to Program Mode, the analog output
value in the CIO Area is either cleared or held depending on the status of the I/O Memory Hold Flag (A500.12). In particular, be careful when
this flag is ON, because the value prior to the mode change will be held and that value will be output refreshed.

Unit Number Switches
The CPU Unit and Analog Input Unit exchange data via words allocated to the Analog Input Unit as a Special I/O Unit. Words are allocated to
Special I/O Units in both the CIO Area and the DM Area.
The words that each Analog I/O Unit uses are determined by the setting of the unit number switches on the front panel of the Unit.
