PRODUCT DESCRIPTION
The ROC364 I/O (Input/Output) Card, shown in Figure Section: 6-1, provides 32 fixed inputs and
outputs for monitoring and control applications. It is used in conjunction with a ROC364 Master
Controller Unit (MCU) that has a FlashPAC (version 2.10C or later) installed.
The card can be used in place of the I/O modules and module racks that are normally used with the
ROC364 MCU. Only one I/O card can be used with an MCU, and an I/O module rack should not be
used between the I/O card and the MCU.

ROC364 Instruction Manual
The ROC364 I/O Card provides these I/O channels:
♦ 12 Discrete Inputs – DIs.
♦ 4 Pulse Inputs – PIs.
♦ 8 Analog Inputs – AIs.
♦ 6 Discrete Relay Outputs – DOs.
♦ 2 Analog Outputs – AOs.
The characteristics (called parameters) of the I/O channels are configured using the ROCLINK
Configuration Software, which is documented in user manual A6051.
Light-emitting diodes (LEDs) provide a visual indication as to the state of the discrete inputs, pulse
inputs, and discrete outputs. A Status LED blinks slowly to indicate normal communications with the
MCU.
The I/O card uses a microprocessor to handle the transfer of data and information between external
devices connected to the I/O channels, and the MCU. Each I/O channel has a removable plug-in
terminal block for field wiring connections. Optional Lighting Protection Modules can be used with
any or all of the I/O channels.
Power for the I/O card, and source power for I/O devices such as transmitters, is provided by the MCU.
Refer to Section 2 of the ROC364 instruction manual for additional information about the MCU.

INITIAL INSTALLATION AND SETUP
If the I/O Card is not already installed onto a ROC364 MCU, use may use the following procedure.
Note that this procedure is for a ROC that is not in service. For an in-service ROC, refer to Section
6.6.2 on Page 6-14.
CAUTION
Failure to exercise proper electrostatic discharge precautions (such as wearing a
grounded wrist strap) may reset the processor or damage electronic components,
resulting in interrupted operations.
CAUTION
When preparing a unit for installation into a hazardous area, change components in
an area known to be non-hazardous.
1. Make sure the MCU has a FlashPAC version 2.10C or later installed.
2. If one or more I/O Module Racks are currently installed, remove them. Each I/O Module
Rack is removed by taking out the four screws securing it to the backplane, and then pulling
it down to unplug the connector at the top of the rack.
3. Install the I/O Card by aligning the connector at the top of the card with the connector on the
bottom of the MCU and push firmly in an upward direction.
4. Insert and tighten the four screws through the card to secure it to the backplane. Extra rack
positions (if any) on the backplane may be left unused.
5. If a Lightning Protection Module is to be installed for certain I/O channels, refer to
Appendix A of the ROC364 instruction manual.
6.3.1 Configuration and Calibration
After an I/O Card is installed, configure and calibrate the I/O channels as needed by using the
ROCLINK Configuration Software. As labelled on the I/O Card itself, the I/O channels are identified
in the ROCLINK software as the following points:
Discrete Inputs (DIs) 1 through 12 ..... Points A1 through A12
Pulse Inputs (PIs) 1 through 4.............. Points A13 through A16
Analog Inputs (AIs) 1 through 8 .......... Points B1 through B8
Analog Outputs (AOs) 1 and 2 ............ Points B9 and B10
Discrete Outputs (DOs) 1 through 6 .... Points B11 through B16

CONNECTING THE I/O CHANNELS TO WIRING
Each I/O channel on the I/O Card is electrically connected to field wiring by a separate plug-in terminal
block. In addition, the ROC enclosures provide a ground bus bar for terminating the sheath on shielded
wiring. The following paragraphs provide information on wiring field devices to each type of I/O
channel.
CAUTION
The sheath surrounding shielded wiring should never be connected to a signal
ground terminal or to the common terminal of an I/O channel. Doing so makes the
I/O channel susceptible to static discharge, which can permanently damage the
channel. Connect the shielded wiring sheath to a suitable earth ground only.
6.4.1 Analog Input Channels
Analog inputs (AIs) monitor current loop and voltage input devices. Each of the I/O Card analog inputs
supply source voltage for powering a transmitter, typically in a current loop installation. The signal
input range is from 1 to 5 volts. Current inputs of 4 to 20 milliamps can be used with the addition of a
250-ohm resistor across the input terminals.
The analog inputs provided on the ROC364 I/O Card are designated Point Number B1 through Point
Number B8. The terminals for connecting wiring are as follows:
T
+
-
Current-limited positive battery voltage for transmitter power
Positive Input
Negative Input (Common)
The analog inputs have three field terminals per channel. If an I/O Conveter Card is installed in the
ROC364 MCU, the “T” terminal provides power for loop-powered devices at 24 volts; otherwise, the
source power at the “T” terminal is the same as the 12 or 24 Vdc power supplied to the MCU. A 250ohm scaling resistor is supplied for use between the “+” and “-” analog input terminals.
The “+” terminal is the positive signal input and the “-” terminal is the signal common. These terminals
accept a voltage signal in the 1 to 5 volt range. Since the “-” terminal is internally connected to
common, the analog input channels function as single-ended inputs only. Note, however, that terminal
“-” is connected to an isolated analog signal common.
When wiring for a 4 to 20 milliamp current signal, leave the 250-ohm resistor installed between the “+”
and “-” terminals. Wire the current loop device “+” lead to the “T” terminal and the device “-” lead to
the AI “+” terminal. Figure Section: 6-2 shows the wiring for a typical current signal.

6.4.2 Analog Output Channels
Analog outputs (AOs) provide a current output for powering analog devices. The ROC364 I/O Card
analog output is a 4-20 mA loop signal.
Two analog outputs are provided on the I/O Card. They are designated Point Numbers B9 and B10.
The second and third terminal positions are connected as follows:

Positive load
Negative load
A schematic representation of the field wiring connections to the analog output channel is shown in
Figure Section: 6-5. The AO provides loop current (4- to 20 mA) from the “+” terminal to nonpowered field devices. If an I/O Conveter Card is installed in the ROC364 MCU, the “+” terminal
provides power for loop-powered devices at 24 volts; otherwise, the source power at the “+” terminal is
the same as the 12 or 24 Vdc power supplied to the MCU. Note that terminal “-” is connected to an
isolated analog signal common.

6.4.3 Discrete Input Channels
Discrete inputs (DIs) monitor the status of relays, solid-state switches, an intrusion switch, or other twostate devices. DI functions support discrete latched inputs and discrete status inputs.
The I/O Card discrete inputs acquire power from the ROC power supply. An LED indicator is included
for each channel. The signal from the field is coupled through an optical isolator providing isolation
from the main circuit board.
6-6
Rev 5/00
ROC364 Instruction Manual
The discrete inputs provided on the I/O Card are configured as Point Number A1 to Point Number A12.
They are connected using the second and third terminal positions as follows:
+
-
Positive Discrete Input
Common
The discrete input operates by providing a voltage across terminals “+” and “-” (see Figure Section: 66), which is derived from internal voltage source Vs. When a field device, such as a relay contact, is
connected across “+” and “-”, the closing of the contacts completes the circuit, which causes a flow of
current between Vs and ground at terminal “-”. This current flow activates the LED and is sensed in
the DI circuitry which, in turn, signals the MCU electronics that the relay contacts have closed. When
the contacts open, current flow is interrupted and the DI circuit signals this to the electronics.
CAUTION
The discrete input is designed to operate only with non-powered discrete devices
such as “dry” relay contacts or isolated solid state switches. Use of the DI channel
with powered devices may cause improper operation or damage to occur.

6.4.4 Discrete Output Channels
The discrete output channels are normally-open, single-pole, single-throw (SPST) relays. The relay
contacts have a 5 amp rating. An LED lights next to the terminal block when the relay coil is
energized. The channels are configured as Point Number B11 to Point Number B16. They can be
software-configured as latched outputs, toggled outputs, or momentary timed outputs.
Use the first and second terminal position for wiring; the third position has no conection. Figure
Section: 6-7 shows a typical discrete output wiring diagram.
NOTE
The Discrete Output channels are designed to operate only with discrete
devices having their own power source. The channels will be inoperative with
non-powered devices.

6.4.5 Pulse Input Channels
Pulse input (PI) channels are used for counting pulses from pulse-generating devices. Each pulse input
is optically isolated from the board electronics and sources power from the +T line of the MCU. LED
indicators monitor the status of each channel.
The I/O Card pulse input circuits are similar to the discrete inputs. The difference is that the pulse input
signal is routed to a pulse accumulator, where the pulses are counted and accumulated.
The pulse inputs provided on the ROC364 I/O Card are configured as Point Numbers A13 through A16.
The pulse inputs can operate at up to 10 kHz.
Each PI channel uses two field terminals, located at the second and third positions of the terminal block.
One terminal is a positive source voltage; the other is the signal return. The terminals are designated as
follows:

Positive Pulse Input (Sourced)
Common
To wire a pulse input channel (shown in Figure Section: 6-8), connect the “+” and “-” field wires to
terminals “+” and “-” on the I/O Card pulse input channel. When the field device completes the circuit
between the “+” and “-” terminals, an LED indicator next to the terminal block lights to show activity,
and the optical circuitry is triggered, producing a signal to the ROC accumulator.
CAUTION
The Pulse Input Source channel is designed to operate only with non-powered
discrete devices such as “dry” relay contacts or isolated solid-state switches. Use of
the channel with powered devices may cause improper operation or damage.

TROUBLESHOOTING AND REPAIR
If multiple I/O channels do not appear to be working, check the STATUS LED on the ROC364 I/O
Card. This LED should be blinking slowly (cycles about 2 seconds long) to indicate normal
communications with the MCU. If it stays off, check for power to the I/O Card. If power is okay, then
the I/O communications is bad due to a problem with the connection to the card, the card itself, or the
MCU. If the MCU appears to be normal, unplug the I/O Card, check the connector, and plug it in
again. If the STATUS is still bad, replace the I/O Card.
In general, to troubleshoot an I/O channel, first check to see how the channel is configured using the
ROCLINK Configuration Software. If the configuration looks correct, then simulate an input (within
the range of the input) or force an output to be produced by using ROCLINK. If an input channel is in
question, you may be able to use one of the outputs on the I/O Card (known to be in working order) to
simulate the needed input. Likewise, if an output channel is in question, you may able to connect it to a
working input channel and check the results.
There are no field repair or replacement parts available for the I/O Card. If the card appears to be
faulty, return it to your Fisher Representative for repair or replacement.
If an I/O point does not function correctly, first determine if the problem is with the field device or the
I/O Card as follows:
CAUTION
Failure to exercise proper electrostatic discharge precautions (such as wearing a
grounded wrist strap) may reset the processor or damage electronic components,
resulting in interrupted operations.
1. Isolate the field device from the ROC by disconnecting it at the I/O terminal block.
2. Connect the ROC to a computer running the ROCLINK configuration software.
3. Perform the appropriate test procedure described in the following paragraphs.
A channel suspected of being faulty should be checked for a short circuit between its input or output
terminals and the ground screw on the termination card. If a terminal not directly connected to ground
reads zero (0) when measured with an ohmmeter, the channel is defective and must be replaced.
NOTE
In the following procedures, references to Terminal B mean the second (middle)
position of the terminal wiring block and references to Terminal C mean the third
(counting left to right) position.

Value read by AI channel
When the value of Filtered Engineering Units (EU) is -25% of span as configured above, it is an
indication of no current flow (0 mA), which can result from open field wiring or a faulty field device.
When the value of Filtered EUs is in excess of 100% of span as configured above, it is an indication of
maximum current flow, which can result from shorted field wiring or a faulty field device.
When the value of Filtered EUs is between the low and high readings, you can verify the accuracy of
the reading by measuring the voltage across scaling resistor Rs (Vrs) with the multimeter. To convert
this reading to the Filtered EUs value, perform the following:
Filtered EUs = [((Vrs - 1)/4) × Span] + Low Reading EU,
where Span = High Reading EU - Low Reading EU
This calculated value should be within one-tenth of one percent of the Filtered EUs value measured by
the ROC. To verify an accuracy of 0.1 percent, read the loop current with a multimeter connected in
series with current loop. Be sure to take into account that input values can change rapidly, which can
cause a greater error between the measured value and the calculated value.
If the calculated value and the measured value are the same, the AI channel is operating correctly.

6.5.2 Analog Output Channels
The Analog Output channel is used for current loop devices. Use the following procedure to check
current loop installations.
Equipment Required:
Multimeter
Personal Computer running ROCLINK Software
1. Taking appropriate precautions, disconnect the field wiring going to the AO channel terminations.
2. Connect a multimeter between the B and C terminals of the channel and set the multimeter to
measure current in milliamps.
3. Using the ROCLINK software, put the AO point associated with the channel under test in Manual
mode (scanning disabled).
4. Set the output to the high EU value.
5. Verify a 20-milliamp reading on the multimeter.
6. Calibrate the analog output high EU value as needed by increasing or decreasing the “Adj D/A
100% Units”.
7. Set the output to the low EU value.
8. Verify a 4-milliamp reading on the multimeter.
9. Calibrate the analog output low EU value by increasing or decreasing the “Adj D/A 0% Units” as
needed.
10. Enable scanning for the AO point, remove the test equipment, and reconnect the field device.
11. If possible, verify the correct operation of the AO channel by setting the high and low EU values as
before (scanning disabled) and observing the field device.
6.5.3 Discrete Input Channels
Equipment Required:
Jumper wire
Place a jumper across terminals B and C. The LED associated with the channel (located on top left of
I/O Card) should light and the status as read by the ROCLINK software should change to “1”. With no
jumper on terminals B and C, the LED should not be lit and the status should be “0”.

Rev 5/00
ROC364 Instruction Manual
6.5.4 Discrete Output Channels
Equipment Required:
Multimeter
Personal Computer running ROCLINK Software
Place the Discrete Output in manual mode using the ROCLINK configuration software. Set the output
status to “0” and measure the resistance across terminals B and C. A reading of 0 ohms should be
obtained. Set the output status to “1” and measure the resistance across terminals B and C. No
continuity should be indicated.
6.5.5 Pulse Input Channels
Equipment Required:
Pulse Generator
Voltage Generator
Frequency Counter
Jumper wire
For both types of channels, there are two methods of testing. One method tests high-speed operation,
and the other method tests low-speed operation.
NOTE
When checking the operation of the Pulse Input channels, ensure the scan rate for
the pulse input is once every 6.5 seconds or less as set by the ROCLINK software.
To verify high-speed operation, connect a pulse generator having sufficient output to drive the channel
to terminals B and C. Connect a frequency counter across terminals B and C. Set the pulse generator
to a value equal to, or less than 10 KHz, and set the frequency counter to count pulses. Verify the count
read by the counter and the count read by the ROC are the same using the ROCLINK software.
To verify low-speed operation, alternately jumper across terminals B and C. The channel LED should
cycle on and off, and the accumulated count should increase.

REPLACEMENT PROCEDURE
6.6.1 Impact on I/O Point Configuration
When an I/O Card is replaced with another I/O Card, it is not necessary to reconfigure the ROC.
If any points or their parameters need to be changed, you can use the ROCLINK configuration software
to make the changes off-line or on-line. If you want to minimize “down time,” before you replace the
card, you can make the needed changes (except for ROC display and FST changes) off-line by first
saving the ROC configuration to disk. Modify the disk configuration, replace the card, and then load
the configuration file into the ROC.
To make changes on-line, replace the card, proceed directly to the configuration display for the affected
points, and modify parameters as needed.
CAUTION
If one or more FSTs, or higher-level points such as a PID loop or AGA Flow, are
configured in the ROC, be sure to reconfigure them according to the changes in I/O
points. Operational problems will occur if you do not reconfigure the ROC.
6.6.2 Replacing the I/O Card
Use the following procedure to replace the I/O Card. The procedure requires using the ROCLINK
Configuration Software.
CAUTION
There is a possibility of losing the configuration and historical data held in RAM
while performing the following procedure. As a precaution, save the current
configuration and historical data to permanent memory as instructed in Section
2.5.2.
CAUTION
When working on units labeled for service in hazardous areas, ensure that the
working environment is currently non-hazardous.
6-14
Rev 5/00
ROC364 Instruction Manual
CAUTION
Failure to exercise proper electrostatic discharge precautions (such as wearing a
grounded wrist strap) may reset the processor or damage electronic components,
resulting in interrupted operations.
CAUTION
During this procedure all power will be removed from the ROC and devices
powered by the ROC. Ensure that all connected input devices, output devices, and
processes remain in a safe state when power is removed from the ROC and when
power is restored.
1. Refer to Section 2.5.2 concerning RAM backup procedures.
2. Disconnect the input power, such as by unplugging the 5-terminal power connector.
3. To remove an existing I/O Card, take out the four screws securing the card to the backplane
and the remove the card by pulling it straight down.
4. To install a new or replacement I/O Card, insert the top-edge connector into the MCU
socket. Push the card upward, seating it firmly. Insert and tighten the four screws.
5. After the card is installed, reconnect the input power.
6. Check the configuration data (including ROC displays) and FSTs, and load or modify them
as required. Load and start any user programs as needed.
7. Verify that the ROC performs as required.
8. If you changed the configuration, save the configuration data to permanent memory.
9. If you changed the configuration, including the history database, FSTs, and ROC displays,
save them to disk. See Section 2.5.2 for more information on saving files.
