Installing the cFP-CTR-502 Wiring the [c]FP-CTR-502 The FP-TB-x terminal base has connections for each FP-CTR-502 channel and for an external power supply to power the input channels and field devices. The cFP-CB-x connector block provides the same connections for the cFP-CTR-502. The V and VSUP terminals are all internally connected, as are the C and COM terminals. © National Instruments Corp. 3 FP-CTR-502 and cFP-CTR-502 Use a 5–30 VDC external power supply for the input channels. The power supply must provide enough current to power all of the input channels and all of the field devices on the output channels. Connect the external power supply to multiple V and VSUP terminals and to multiple C and COM terminals as needed to ensure that the maximum current through any terminal is 2 A or less. Install a 2 A maximum, fast-acting fuse between the external power supply and the V or VSUP terminal on each channel. Install a 1 A maximum, fast-acting fuse suitable for the load at the VOUT terminal. The detailed wiring diagrams in this document show fuses where appropriate. Table 1 lists the terminal assignments for the signals of each channel. Terminal assignments are also listed on the side panel of the cFP-CTR-502 and under the slide-in card on the front of the FP-CTR-502. Table 1.

Each channel also has VSUP and COM terminals that can supply power to field devices or provide additional connections to the external power supply. You can connect the eight count-input channels and four gate-input channels to devices with sinking outputs. The [c]FP-CTR-502 has sourcing inputs, which means that the VIN terminal provides a path to a voltage supply. The [c]FP-CTR-502 input channels are optically isolated from the rest of the FieldPoint bank and have current-limiting circuitry. All the input channels are referenced to the V and VSUP terminals. In the ON state, an optoisolator is turned on between the positive external supply voltage (V and VSUP) and the input (VIN). When choosing your external devices and power supply, keep in mind that the input-logic thresholds are defined by the power supply as detailed in the Specifications section. Vthreshold = VSUP – VK where Vthreshold is the threshold voltage for the channel VSUP is the supply voltage, measured across VSUP and COM VK has a value of 2–3 V When VIN, the voltage across VIN and COM, is lower than Vthreshold , the channel is ON. Therefore, if you connect a 24 V power supply to the [c]FP-CTR-502, an input channel registers an ON state when © National Instruments Corp. 5 FP-CTR-502 and cFP-CTR-502 VIN is 21 V or lower, and an OFF state when VIN is 22 V or higher. The channel state is indeterminate when VIN is between 21 V and 22 V. Ensure that the sinking-output devices have OFF state leakage currents of less than 0.3 mA so they do not send false ON state readings to the [c]FP-CTR-502. You must use the same ground for all of the input and output channels on the [c]FP-CTR-502.

Wiring a Count-Input or Gate-Input Channel to a Sinking-Output Device Outputs Each output channel has one output terminal, VOUT. Each channel also has VSUP and COM terminals that can supply power to field devices. The [c]FP-CTR-502 has sinking outputs, which means that VOUT provides a path to ground. You can connect the [c]FP-CTR-502 outputs to sourcing-input devices. In the ON state, a transistor is turned on between the output (VOUT) and common (C and COM). In the OFF state, this transistor is turned off, allowing only a small leakage current to flow. Ensure that the load on any output channel does not draw more than 1 A.

Wiring an Output to an Externally Powered Sourcing-Input Device © National Instruments Corp. 7 FP-CTR-502 and cFP-CTR-502 Configuring Count-Input Channels Channels 0–7 are count-input channels. In FieldPoint software, you can configure each count-input channel to operate with attributes and commands. In the Channel Configuration dialog box, select attributes for each channel from the Attributes menu and commands from the Commands menu. The following sections describe the different attributes and commands you can select when you are configuring the count-input channels. For more information about using FieldPoint software, refer to the FieldPoint software help file. Terminal Count To set the terminal count, enter a value from 0 to 65,535 in the Value field. The default value is 65,535. When the count-input channel exceeds its terminal count, the count resets to 0 and triggers any outputs associated with it. For more information about associating outputs with a count-input channel, refer to the Configuring Output Channels section. The count-input channel also sends a count trigger to the next count-input channel if that channel is set to use the previous channel as the count source. Channel Status In FieldPoint software, the [c]FP-CTR-502 reports one of the following statuses: Successful or Overflow since last read. The default channel status is Successful. If a count-input channel exceeds the terminal count, the channel resets to 0 and starts counting again, and the channel status changes to Overflow since last read. Count Source Select one of the following count sources from the Value menu: External Count Input, Previous Channel, 1 kHz Reference, or 32 kHz Reference. Select External Count Input, 1 kHz Reference, or 32 kHz Reference to configure the channel so that it counts low-to-high (off-to-on or rising-edge) transitions of the count source. Select Previous Channel if you want the channel to count the number of times that the previous count-input channel reaches its terminal value and resets to 0. You can configure multiple counters to operate as one large counter. You can slave Channel 1 FP-CTR-502 and cFP-CTR-502 8 ni.com to Channel 0, Channel 0 to Channel 7, Channel 7 to Channel 6, and so on. If you select this option for all of the channels, no counting occurs. Gate Source Select Gate Input 0–3 from the Value menu to associate a gate-input channel with a count-input channel. If the count-input channel uses one of the external gate inputs, counting is enabled when the gate-input signal is high and is disabled when the signal is low, as shown in Figure 6. The gate-input signal is high when the channel is ON. The external device determines the high and low intervals of the gate-input signal. If you do not associate a gate-input channel with the count-input channel, select Always Disabled or Always Enabled. Select Always Enabled if you want the count-input channel to count at all times, even if there is nothing wired to the gate input. Always Enabled is the default value. Gate Input Count Input 0 0 1 2 3 3 3 3 4 5 6 6 Figure 6. Gate Source Set to External Gate Input Read Reset Mode You can configure each count-input channel to reset each time the FieldPoint network module reads it by selecting Reset on Read from the Value menu. A read-initiated reset also resets any outputs associated with the target channel. The default is Don’t Reset On Read. Read Reset mode is not intended to be used with FieldPoint Ethernet network modules. Note © National Instruments Corp. 9 FP-CTR-502 and cFP-CTR-502 Noise Rejection Each count-input channel has a software-enabled lowpass filter that you can set to reject frequencies above 200 Hz or 50 kHz. Select 200 Hz or 50 kHz from the Value menu to configure noise rejection. The default is 50 kHz. Control You can set the Control command to increment or reset by selecting Increment or Reset from the Action menu. The increment-control command increases the count-input channel in value by one. The reset-control command resets the count-input channel. The control commands ignore the gate-source setting and gate-input state. Configuring Gate-Input Channels Channels 8–11 are gate-input channels. The only difference between the input circuits of the gate-input channels and those of the count-input channels is that the gate-input channels do not have a programmable lowpass filter. The states of the gate inputs can always be read as simple digital inputs on Channels 8–11. You do not need to configure anything in software for the gate-input channels. Configuring Output Channels Channels 12–15 are digital output channels. In the Channel Configuration dialog box of FieldPoint software, you can select attributes for each output channel from the Attributes menu. The following sections describe the different attributes you can select for output channels. Output Source You can configure each output channel to operate either as an associated output for one of the eight count-input channels or as a generic digital output. Select Counter Channel 0–7 from the Value menu if you want the digital output channel to operate as an output for a corresponding count-input channel. Select Discrete Data from the Value menu if you want to use this channel as a generic digital output. When you write data to an output channel, you affect the output state only if you configure the Output Source as Discrete Data. FP-CTR-502 and cFP-CTR-502 10 ni.com Output Mode For each output channel select one of the following output modes from the Value menu: Toggle, Reset Off; Toggle, Reset On; On Pulse; or Off Pulse. The output modes work only if you select Counter Channel 0–7 for the Output Source. The following sections describe the different output modes. Toggle, Reset Off In Toggle, Reset Off mode, the output channel starts low and goes high when the terminal count is exceeded. The output channel returns to low the next time the terminal count is exceeded or when you send a reset command to the associated count-input channel. In Figure 7, the terminal count is 4. Count Input 0 1 2 3 4 0 1 2 3 4 0 1 Output Figure 7. Output of a Channel Set to Toggle, Reset Off Mode Toggle, Reset On In Toggle, Reset On mode, the output channel starts high and goes low when the terminal count is exceeded.

Output of a Channel Set to Off Pulse Mode FP-CTR-502 and cFP-CTR-502 12 ni.com Application Note: Generating a Continuous Pulse Train You can use two [c]FP-CTR-502 count-input channels and one output channel to generate a continuous pulse train with a controllable duty cycle and period. The first count-input channel serves as a clock prescaler and divides the input clock by a fixed value. This generates a slower clock for the second count-input channel, which serves as the pulse counter. The pulse counter is the output source for the output channel. Figure 11 shows the components of a continuous pulse train. Clock Input Prescaler Counter n Internal Connection Pulse Counter n+1 Internal Connection Output [c]FP-CTR-502 Pulse Output Terminal Figure 11. Continuous Pulse Train Step 1. Set Up the Prescaler Counter To set up the prescaler counter, complete the following steps: 1. If you do not need to scale the frequency of your clock input, you can configure the pulse counter to use the clock input directly instead of the prescaler counter. To set up the pulse counter, skip to Step 2. Set Up the Pulse Counter. 2. Select two count-input channels and an output channel to use. Select count-input channels that are numbered sequentially (for example, Channels 1 and 2, 5 and 6, or 7 and 0). The count-input channel with the lower number is the prescaler counter and the count-input channel with the higher number is the pulse counter. 3. Set the Gate Source attribute of the prescaler counter to Always Enabled, and set Read Reset Mode to Don’t Reset On Read. © National Instruments Corp. 13 FP-CTR-502 and cFP-CTR-502 4. Set the Count Source of the prescaler counter to the clock on which you want to base your pulse train. This can be the external counter input or one of the [c]FP-CTR-502 internal references. 5. Subtract 1 from the value that you want to divide the input clock by, and set the terminal count of the prescaler counter to the result. For example, a terminal count of 4 divides the input clock by 5. If you use the 1 kHz reference as the prescaler count source, this setting generates a 200 Hz clock for the pulse counter. To determine the frequency of the prescaler output, use the following formula: f src f pre = --------------------------term pre + 1 where fpre is the frequency of the prescaler counter output fsrc is the count-input frequency for the prescaler counter termpre is the terminal count value for the prescaler counter Step 2. Set Up the Pulse Counter To set up the pulse counter, complete the following steps: 1. Set the Count Source of the pulse counter (the count-input channel with the higher number) to Previous Channel so that it uses the output from the prescaler counter. If you are not using a prescaler counter, set the Count Source to the clock on which you want to base your pulse train. Note 2. Set the Read Reset Mode of the pulse counter to Don’t Reset On Read and set the Gate Source to Always Enabled. 3. Subtract 1 from the value that you want to divide the count input by and set the Terminal Count of the pulse counter to the result. The internal output from the pulse counter triggers the output channel that you selected for the pulse train output. FP-CTR-502 and cFP-CTR-502 14 ni.com To determine the frequency of the output from the pulse counter, use the following formula: f pre f pulse = -------------------------------term pulse + 1 where fpulse is the pulse counter output frequency fpre is the prescaler counter output frequency termpulse is the terminal count value for the pulse counter Step 3. Configure the Pulse Train Output Channel To configure the pulse train output channel, complete the following steps: 1. For the output channel that you selected, set the Output Source to the pulse-counter channel. 2. Set the Output Mode of the output channel. To generate a pulse train with variable duty cycle, use one of the pulse modes—On Pulse or Off Pulse. To generate a 50% duty-cycle pulse train, use one of the toggle modes. To determine the duty cycle, use the following formulas: For On Pulse mode, use 1 d = -------------------------------term pulse + 1 For Off Pulse mode, use 1 d = 1 – -------------------------------- term pulse + 1 where d is the duty cycle of the pulse train termpulse is the terminal count value of the pulse counter When you set the output to one of the pulse modes, the frequency of the pulse train (fpulse) is the same as that shown in Step 2. Set Up the Pulse Counter , but the output frequency is half that value when you set the output channel to one of the toggle modes. © National Instruments Corp. 15 FP-CTR-502 and cFP-CTR-502 Status Indicators Figure 12 shows the status indicator LEDs on the [c]FP-CTR-502. Figure 12. Status Indicators The [c]FP-CTR-502 has two green status LEDs, POWER and READY. After you install the [c]FP-CTR-502 onto a terminal base or backplane and apply power to the connected network module, the green POWER indicator lights and the [c]FP-CTR-502 informs the network module of its presence. When the network module recognizes the [c]FP-CTR-502, it sends initial configuration information to the [c]FP-CTR-502. After the [c]FP-CTR-502 receives this initial information, the green READY indicator lights and the module is in normal operating mode. In addition to the green POWER and READY indicators, each channel has a numbered, green status indicator that lights when the channel is in the ON state.

Isolation and Safety Guidelines Read the following information before attempting to connect the [c]FP-CTR-502 to any circuits that may contain hazardous voltages. Caution This section describes the isolation of the [c]FP-CTR-502 and its compliance with international safety standards. The field wiring connections are isolated from the backplane and the inter-module communication bus. The isolation is provided by the module, which has optical and galvanic isolation barriers designed and tested to protect against transient fault voltages of up to 2,300 Vrms. FP-CTR-502 and cFP-CTR-502 16 ni.com Follow these guidelines to ensure a safe total system. • The [c]FP-CTR-502 has a safety isolation barrier between the I/O channels and the inter-module communication bus. There is no isolation between channels unless otherwise noted. If any of the channels on a module are wired at a hazardous potential, make sure that all other devices or circuits connected to that module are properly insulated from human contact. • Do not share the external supply voltages (the V and C terminals) with other devices (including other FieldPoint devices), unless those devices are isolated from human contact. • For Compact FieldPoint, you must connect the protective earth (PE) ground terminal on the cFP-BP-x backplane to the system safety ground. The backplane PE ground terminal has the following symbol stamped beside it: . Connect the backplane PE ground terminal to the system safety ground using 14 AWG (1.6 mm) wire with a ring lug. Use the 5/16 in. panhead screw shipped with the backplane to secure the ring lug to the backplane PE ground terminal. • As with any hazardous voltage wiring, make sure that all wiring and connections meet applicable electrical codes and commonsense practices. Mount terminal bases and backplanes in an area, position, or cabinet that prevents accidental or unauthorized access to wiring that carries hazardous voltages. • Operate the [c]FP-CTR-502 only at or below Pollution Degree 2. Pollution Degree 2 means that only nonconductive pollution occurs in most cases. Occasionally, however, a temporary conductivity caused by condensation must be expected. • Refer to the FieldPoint product label for regulatory certification under hazardous location standards. If the FieldPoint product is not certified for operation in hazardous locations, do not operate it in an explosive atmosphere or where there may be flammable gases or fumes. © National Instruments Corp. 17 FP-CTR-502 and cFP-CTR-502 Specifications The following specifications are typical for a range of –40 to 70 °C unless otherwise noted.1 Input Characteristics Number of channels.......................... 12 (8 count, 4 gate) Input type .......................................... 5–30 VDC sourcing, compatible with TTL devices and other 5, 12, or 24 VDC devices Maximum input voltage.................... 30 VDC Input threshold level (VSUP is the external supply voltage) Typical ........................................
