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

Inputs
Each input channel has one input terminal, VIN. 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.
V
threshold = 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

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.
Note You must use the same ground for all of the input
and output channels on the [c]FP-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: Successfulor 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

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.

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.
Note Read Reset mode is not intended to be used with
FieldPoint Ethernet network modules.

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.

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.

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.

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.

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:
fsrc
fpre = ----------------------------
termpre + 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.
Note If you are not using a prescaler counter, set the
Count Source to the clock on which you want to base
your pulse train.
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

To determine the frequency of the output from the pulse counter,
use the following formula:
fpre
fpulse = --------------------------------
termpulse + 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 =
termpulse + 1
For Off Pulse mode, use
d = 1 –
1
--------------------------------
termpulse + 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.

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.
Upgrading the FieldPoint Firmware
You may need to upgrade the FieldPoint firmware when you add
new I/O modules to the FieldPoint system. For more information
on determining which firmware you need and how to upgrade the
firmware, go to ni.com/info and enter fpmatrix.
Isolation and Safety Guidelines
Caution Read the following information before
attempting to connect the [c]FP-CTR-502 to any circuits
that may contain hazardous voltages.
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

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.
