The products described in this instruction manual are manufactured
by Reliance Electric Industrial Company.
The 4 Input 0Ć10 Volt Analog Rail module allows you to connect four
input 0Ć10V analog signals to AutoMater, AutoMaxr and DCS 5000
systems. Typically, the Analog Rail module is used with
potentiometers, valve actuators, pressure or flow transducers, and
meters in both drive control systems and process control systems.
The Analog Rail module is hardwareĆconfigurable by means of a
faceplate switch to emulate one of two types of devices, AutoMate
Rails or AutoMate Local Heads. In some hardware configurations, the
type of interface device available for the Analog Rail module will
determine the mode of operation that can be selected (see
figure 1.1).
The Analog Rail module operates in Local Head mode when it is
connected directly to one of the processor's four I/O ports in
AutoMate systems, to an AutoMate Local I/O Processor, or to one of
the four I/O ports of the DCS 5000/AutoMax Remote I/O Head in DCS
5000/AutoMax systems. The Analog Rail data will take up four
registers in the host when operating in Local Head mode.
The module operates in Rail mode when it is connected to one I/O
port of a Local I/O Head, which in turn is connected to one I/O port of
an AutoMate processor. The Analog Rail module will occupy one
register of the host in Rail mode. The Rail mode is used to expand
the I/O address space available through the front I/O port of the
processor by multiplexing each group of four analog points through
one register. Note that the Analog Rail module cannot be used with
the Local I/O Head in DCS 5000/AutoMax systems.
The Analog Rail module operates in Rail mode when it is connected
to one I/O port of the Power Module Interface (PMI) Processor
(B/M 60000), which is in turn connected to a Universal Drive
Controller (UDC) module (M/N 57552) which resides in an AutoMax
rack.
The remainder of this manual describes the functions and
specifications of the module. It also includes a detailed overview of
installation and troubleshooting procedures, as well as examples of
configuration and programming.

The faceplate of the module contains three electrical connectors
labeled Input", Analog I/O", and Input Power" (reading top to
bottom). The top connector is used for connection to the I/O port. A
cable (M/N 45C5) is provided for this purpose. The second
connector, labeled Analog I/O", is a numbered, 12Ćpoint removable
plug connector with screwĆtype terminal points. Three successive
terminal points are reserved for each channel's connection to
external hardware. The Analog Inputs" terminals are designed for
14Ć22 AWG wire.
The third connector on the faceplate, also a removable plug
connector with screwĆtype terminal points, is used for input power.
The terminal points are labeled. The top two points are used if the
power source is 24 VDC. The bottom two points are used if the power
source is 120 VAC. The Input Power" terminals are designed to use
14 AWG wire. A terminal stud for connecting a grounding conductor
is provided on the bottom of the rightĆhand mounting flange.
The module faceplate also contains two LEDs, a mode switch, and a
fuse holder and fuse. The LED labeled PWR OK" indicates that the
I/O port, the external power source, and the internallyĆgenerated
voltages necessary for operation of the module are present. The
COM OK" LED indicates whether all four channels are successfully
communicating with the host.
The switch labeled Mode" is used to select between Local Head"
and Rail" mode. Note that the position of the switch is read only
once at the time power is turned on to the Reliance device that is
connected to the Analog Rail module. The mode will remain fixed as
long as this device is powered up.
As shipped from the factory, the fuse holder on the bottom of the
faceplate contains a .25A fuse for 120 VAC input power. If input
power will be 24 VDC, you need to replace the fuse with the .75A
fuse included along with the Analog Rail module.

2Ć3
      
The Analog Rail module contains four analog input channels that
convert 0Ć10V analog input signals to proportional values between 0
and 4095, equal to 12 bits of digital data. Input signals are filtered
through a second order lowĆpass filter.
The A/D conversions are triggered by the actual I/O update
sequences. The conversion rate is therefore dependent upon the
scan time of the application task. See figure 2.2 for a typical input
circuit.

Figure 2.2 ĆTypical Input Circuit

The Analog Rail module is factory calibrated and requires no

offset/gain adjustment. All four analog input channels are referenced
to the same common. This common is isolated from both the external
power supply and the I/O port connection.
The module incorporates extensive diagnostics. In Rail mode, check
bits are monitored for accuracy on every transfer of data between the
host and the module. In Local Head mode, parity bits are monitored
for accuracy on every transfer of data. A Rail fault LED on the
processor, Remote Head, or Local Head will be illuminated if the
check bits or parity bits are wrong and all transmission will stop after
n retries, where n is a value determined by the host's software
(average n = 4 for AutoMax; AutoMate n = 2).
In the event of a rail fault, the COM OK" LED on the module will go
off. If any power required by the module, i.e., the +5 Volts from the
I/O port required for communication, the external power supply, or
the power required by the Analog input section, is not within
specified limits, the PWR OK" LED will go off.

2Ć4
3.0 INSTALLATION
This section describes how to install and replace the Analog Rail
module. Note that analog signals are sensitive to variations in
temperature. The Analog Rail module is designed to perform
optimally at room temperature, approximately 25oC. In all cases, the
ambient temperature of the installation must be maintained in the
range specified in Appendix A to ensure the highest possible
accuracy.

DANGER
THE USER IS RESPONSIBLE FOR CONFORMING WITH THE NATIONAL
ELECTRICAL CODE AND ALL OTHER APPLICABLE LOCAL CODES. WIRING
PRACTICES, GROUNDING, DISCONNECTS, AND OVERĆCURRENT
PROTECTION ARE OF PARTICULAR IMPORTANCE. FAILURE TO OBSERVE
THIS PRECAUTION COULD RESULT IN SEVERE BODILY INJURY OR LOSS OF
LIFE.

DANGER
DO NOT TOUCH THE CONNECTORS ON THE FACEPLATE IF THERE IS
POWER ON THE WIRES ATTACHED TO THE PLUG CONNECTOR SCREW
TERMINALS. ALWAYS TURN OFF POWER BEFORE HANDLING A
CONNECTOR THAT IS WIRED. FAILURE TO OBSERVE THIS PRECAUTION
COULD RESULT IN SEVERE BODILY INJURY OR LOSS OF LIFE.

CAUTION
THE ANALOG RAIL MODULE IS DESIGNED TO BE POWERED BY EITHER 24
VDC OR 120 VAC. CONNECT THE PROPER POWER SOURCE TO THE
MODULE. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN
DAMAGE TO OR DESTRUCTION OF THE EQUIPMENT.

3.1 Wiring
To reduce the possibility of electrical noise interfering with the proper
operation of the control system, exercise care when installing the
wiring between the module and the external hardware.
Use shielded twisted pair for all wiring between the Analog Rail
module and the external hardware. Belden
8761 or an equivalent
cable type is recommended. Cable lengths should be limited to 50
feet maximum. For detailed recommendations refer to IEEE 518.

3Ć1
       
Use the following procedure to install the Analog Rail module.
Step 1. Using the mounting dimensions shown in figure 3.1,
prepare the necessary mounting provisions on the panel.
The module is designed to be mounted vertically using
four #10 or M5 bolts or studs. Multiple modules should be
mounted side by side. The flange width of two modules
side by side is sufficient to dissipate the heat produced by
the modules. The modules can also be mounted one
above the other, but since this hardware configuration
does not allow the most efficient heat dissipation, the
minimum clearance between the module chassis is 3".
See figure 3.1.

 Step 2. If the power supply you are using is 24 VDC, replace the
factoryĆinstalled .25A fuse with the .75A fuse that came in
the shipping box with the module. Use a screwdriver to
release the fuse holder located on the Analog Rail module
faceplate. Pull the fuse holder out of the module.
Take the .25A fuse out of the fuse holder and replace it
with the .75A fuse. ReĆinsert the fuse holder into the
module. Turn the screwdriver clockwise while pressing
down on the fuse holder. The fuse holder must be flush
against the faceplate.
Step 3. Mount the Analog Rail on the panel and attach it securely
with #10 (M5) studs or bolts.
Step 4. Make certain that no voltage is present on the wires that
will be used to provide 120 VAC or 24 VDC power to the
Analog Rail module. Use either a 120 VAC or 24 VDC
power supply, but not both.
Step 5. Using 14 AWG wire, connect input power to the screw
terminals on the Input Power" plug connector on the
faceplate as shown below. Strip off approximately 5/16" of
insulation from the wires.

THIS PRECAUTION COULD RESULT IN SEVERE BODILY INJURY OR LOSS OF
LIFE.

Step 7. Turn off all power to any external hardware that will
provide input signals to the module or be powered by the
module.
Step 8. Attach a retainer clip to the connector at each end of the
I/O Rail cable (M/N 45C5). Note that faceplate connectors
have slots that correspond to the part of the retainer clip
that protrudes away from the cable connector. The retainer
clip is used to assure a tight connection between the cable
and faceplate connectors.

3Ć3
 Step 9. Using 14Ć22AWG wire, connect external hardware to the
Analog Inputs" plug connector on the faceplate as shown
below. Strip off approximately 5/16" insulation from the
wires.

Step 11. Turn off power to the Reliance device that will be
connected to the Analog Rail module.
Step 12. Set the Mode" switch on the faceplate of the module to
the desired position.
Step 13. Connect the I/O Rail cable between the Analog Rail
connection labeled Input" and an I/O port on the
Reliance device that will communicate with the module.
Turn on power to the Reliance device that will
communicate with the module. Recall that the Mode
switch is read each time the Reliance device connected to
the Analog Rail module is powered up.
Step 14. The Analog Rail installation is now ready for testing.
Inspect all work to assure that the installation has been
performed properly.
Step 15. Turn on power to the Input Power" wiring. Turn on power
to the external hardware. See Appendix A for power
supply specifications.
Step 16. Verify that the hardware has been installed correctly.
Before testing, insure that the external hardware will not
respond to output signals from the Analog Rail module.

3Ć5
 For AutoMate systems, you must configure the AutoMate
processor using the AutoMate Programming Executive
(APX) before testing. See section 4.0 for more information.
After configuring the module, use the APX Point Monitor
function to test the module. You can test the Analog Rail
module input channels by verifying that the input signal in
the channel (0 to 10V) is proportional to a voltmeter
reading at the terminal points.
For DCS 5000, AutoMax, or Distributed Power DĆC Drive
systems, use the DCS 5000 or AutoMax Programming
Executive software I/O Monitor function, respectively. To
test the input channels, verify that the input signal in the
channel (0 to 10V) is proportional to a voltmeter reading at
the terminal points.

      
Use the following procedure to replace the module.
Step 1. Stop any application programs that are running.
Step 2. Turn off power to the external hardware connected to the
input channels on the faceplate of the module.
Step 3. Turn off power to the Analog Rail module (120 VAC or
24 VDC).
Step 4. Turn off power to the Reliance device connected to the
Analog Rail module.
Step 5. Disconnect the I/O Rail cable from the Analog Rail module.
Step 6. Without disconnecting the wiring, remove the 12Ćpoint
terminal from the faceplate and set aside.
Step 7. Without disconnecting the wiring, remove the 4Ćpoint
terminal from the faceplate and set aside. Disconnect the
ground wire from the bottom rightĆhand flange.
Step 8. Loosen the screws that hold the Analog Rail module to the
panel and remove the module.
Step 9. If the power supply you are using is 24 VDC, you need to
replace the factoryĆinstalled .25A fuse in the new module
with the .75A fuse that came in the shipping box with the
module. Use a screwdriver to release the fuse holder
located on the Analog Rail module faceplate. Pull the fuse
holder out of the module.
Take the .25A fuse out of the fuse holder and replace it
with the .75A fuse. ReĆinsert the fuse holder into the
module. Turn the screwdriver clockwise while pressing
down on the fuse holder at the same time. The fuse holder
must be flush against the faceplate.
Step 10. Remove the two plug connectors from the faceplate of the
new module by pulling them firmly away from the
faceplate.
Step 11. Place the new module over the pattern drilled and attach it
securely to the wall with #10 or M5 studs or bolts.
Step 12. Attach the original 12Ćpoint and 4Ćpoint connectors with
wiring to the faceplate of the module. Use the stud marked
GND" (ground) on the bottom right flange of the module
to connect a ground wire.

3Ć6
Step 13. Set the Mode" switch on the faceplate of the module to
the desired position.
Step 14. Connect the I/O Rail cable between the Analog Rail
connection labeled Input" and any rail connector on the
Reliance device that will communicate with the module.
Turn on power to the Reliance device connected to the
module. Recall that the Mode switch is read each time the
Reliance device connected to the Analog Rail module is
powered up. If applicable, reĆconnect the cable between
the Local I/O Head, or the DCS/AutoMax Remote I/O
Head, and the host.
Step 15. Turn on power to the Analog Rail module Input Power"
connections.
Step 16. Turn on power to the external hardware connected to the
Analog Rail module.
Step 17. Verify that the hardware has been installed correctly.
For AutoMate systems, use the APX Point Monitor function
to test the module. To test the input channels, verify that
the input signal in the channel (0 to 10V) is proportional to
a voltmeter reading at the terminal points.
For DCS 5000, AutoMax, or Distributed Power DĆC Power
systems, use the DCS 5000 or AutoMax Programming
Executive software I/O Monitor function, respectively. To
test the input channels, verify that the input signal in the
channel (0 to 10V) is proportional to a voltmeter reading at
the terminal points.

This section describes how the data is organized in the module and
provides examples of how the module is accessed by application
programs.
When creating application programs, the programmer should
estimate the magnitude of input signals because they must be in the
specified range of the Analog Rail module (0Ć10V). Input signals
greater than 10V will be clamped at 4095. Input signals greater than
approximately 11.3V will also cause the overĆrange bit (12 decimal;
14 octal) to be set to 1. Signals less than 0V are clamped at zero (0).
Signals less than approximately -1V will also cause the underĆrange
bit (13 decimal; 15 octal) to be set to 1. See figure 4.1.

4.1 Analog Rail Module in AutoMate Systems

This section describes how the Analog Rail is used with AutoMate
systems. Local Head mode allows all four channels on the module to
be updated at the end of the scan (normal I/O update rate in this
configuration), or during the scan using AIN blocks (see section
4.1.4). Rail mode allows only one channel to be updated at the end
of the scan (normal I/O update rate in this configuration), or all four
channels to be updated during the scan if AIN blocks are used.

4Ć1
        
       
Configuration is the process of describing in software how the
hardware and software in the system are related. The Analog Rail
module is configured using the AutoMate Programming Executive
(APX) software, M/N 45C130 or 45C131. Select CONFIGURE
SYSTEM from the main menu to create the configuration.
Note that the Analog Rail module can also be configured using the
AutoMate Programming System (APS) software, M/N 45C134,
45C141, 45C142, or 45C143. Refer to instruction manual J2Ć3041 for
additional information.
The Analog Rail module is configured depending upon the mode in
which it is being used. See figures 4.2, 4.3, 4.4, 4.5, and 4.6 for how
to configure the Analog Rail for use with AutoMate processors. The
sample configurations are shown as they appear on the APX screen.
Unless otherwise noted, all references to the AutoMate 20, 30, and 40
will also apply to the 20E, 30E and the 40E, respectively.

In Rail mode, the Analog Rail module is imaged in one I/O register of
the processor. Data from one of the four channels will occupy the
register as a function of the channel select bits. The active channel is
updated at the end of each scan. For input channels, the two channel
select bits in the register must be set to the appropriate input channel
number. After the I/O update, the register contains the data in the
format shown in figure 4.7.

Figure 4.7 Ć Rail Mode Register Image for Input Channels

The Analog Rail module data may also be accessed in the middle of
the scan (as opposed to the end of the scan, which is the normal
mode of operation for digital rail I/O) using the appropriate number of
Analog In (AIN) blocks. The AIN block will check whether the
overĆrange or underĆrange bits have been set by the module and the
error coil will be energized, if applicable. See section 4.1.4 for more
information about the AIN block.
Note that the AIN block is supported by the AutoMate 20E
M/N 45C224 and 45C225, but not the AutoMate 20 (M/N 45C20,
45C21, 45C220, 45C221) by APX Version 3.0 and later.
For processors that do not support the AIN block, you can use the
MOVE block to move data in and out of the registers assigned and to
determine the channel select bits. OverĆrange and underĆrange bits
should be used as inputs to error coils. The I/O update will occur
automatically at the end of each scan. See Appendix C for a sample
AutoMate program that reads from the Analog Rail module without
using AIN blocks.

4Ć7
 4.1.3 AutoMate Programming in Local Head Mode
In Local Head mode, the module is imaged in four I/O registers of the
processor. Data from all four channels is always available and will be
updated at the end of each scan. It is not necessary to select the
channel. After the I/O update, the register contains the data in the
format shown in figure 4.8.

The Analog Rail module data may also be accessed in the middle of
the scan (as opposed to the end of the scan) using the appropriate
number of Analog In (AIN) blocks. The AIN block will set the
overĆrange or underĆrange bits if applicable. See section 4.1.4 for
more information about the AIN block.
Note that the AIN block is supported by the AutoMate 20E
M/N 45C224 and 45C225, but not the AutoMate 20 (M/N 45C20,
45C21, 45C220, 45C221) by APX Version 3.0.
For processors that do not support the AIN block, you can use the
MOVE block to move data in and out of the registers assigned.
OverĆrange and underĆrange bits should be used as inputs to error
coils. The I/O update will occur automatically at the end of each scan.
See Appendix C for a sample AutoMate program that reads from the
Analog Rail module without using the AIN block.

4Ć8
         
The AIN block is used to read inputs from the Analog Rail module.
AIN is supported for the A20E. The AIN block makes it possible to
update the channels on the Analog Rail module during the scan
instead of at the end of the scan (the standard AutoMate I/O update).
The block also makes it possible to update all four channels during
the scan in Rail mode, a hardware configuration which would
otherwise allow only one channel on the module to be updated. The
format of the AIN block is shown in figure 4.9.

 4.2 Analog Rail Module in DCS 5000/AutoMax
Systems
This section describes how the Analog Rail module is used with
DCS 5000/AutoMax systems.

4.2.1 Configuring the Analog Rail Module with a

DCS 5000/AutoMax Remote I/O Head
The Analog Rail module is used in the Local Head mode when the
host is a DCS 5000/AutoMax Remote I/O Head. For AutoMax Version
3.0 and later, the Analog Rail module is configured using the
AutoMax Programming Executive. Refer to instruction manual JĆ3750
for more information. For DCS 5000 or AutoMax Version 2.1 or earlier,
the module is defined in the configuration task for the master rack
using the DCS 5000 or AutoMax Programming Executive software.
See instruction manual JĆ3649 for more information on the
configuration task.
For DCS 5000 or AutoMax Version 2.1 or earlier, use the RIODEF
statement to define each channel on the Analog Rail module as a
separate register. Note that in addition to defining each channel as a
register, you can also define the overĆrange and underĆrange bits for
each channel separately. These bits can also be defined using the
RIODEF statement. Use the following format for the RIODEF
statement:
nnnnn RIODEF name[MASTER_SLOT=m, DROP=d, SLOT=s, REGISTER=r, BIT=b]

where:
nnnnn Ć Configuration task line number; range 1Ć32767.
name Ć Symbolic name of channel, ending with % (integer) for
registers, @ (booleans) for bits.
m Ć Slot in rack containing DCS 5000/AutoMax master remote
I/O module; range 0Ć15.
d Ć Drop number of DCS 5000/AutoMax Remote I/O Head;
range 1Ć7.
s Ć Communication port on the DCS 5000/AutoMax Remote
I/O Head to which the Analog Rail module or Local I/O
Head is connected; range 0Ć3.
r Ć Register number; range 0Ć3.
b Ć Optional field defining the bit position within the register
number; range 0Ć15.

4.2.2 Configuring the Analog Rail Module with a Power

Module Interface Processor Host
The Analog Rail module is used in the Rail mode when the host is a
Power Module Interface (PMI) Processor. Beginning with AutoMax
Version 3.3, the Analog Rail module is configured using the AutoMax
Programming Executive. Refer to instruction manual J2Ć3045 for
more information.

4Ć10
4.2.3 DCS 5000/AutoMax Programming
When programming the Analog Rail module, it is recommended that
you monitor the state of the overĆrange and underĆrange bits for the
input channels. You can check the status of the appropriate bits
directly if they were defined in the configuration. You can also use the
BASIC expression AND with the variable name assigned to the input
channel to mask off the 12 bits of analog data and read the values in
the overĆrange and underĆrange bits. Any nonĆzero result means that
the value is out of range. See the following three statements for
examples of how to detect values out of range. Use the hexadecimal
values shown to mask off the analog data.
The value in the channel defined as CHANNEL_2 is either overĆrange
or underĆrange:
10000 RANGE_ERROR@ = CHANNEL_2 AND 3000H
The value in the channel defined as CHANNEL_2 is overĆrange:
11000 OVER_ERROR@ = CHANNEL_2 AND 1000H
The value in the channel defined as CHANNEL_2 is underĆrange:
12000 UNDER_ERROR@ = CHANNEL_2 AND 2000H

This section explains how to troubleshoot the Analog Rail module. If

you cannot correct the problem using the instructions below, the unit
is not userĆserviceable.

5.1 Both LEDs on the Faceplate are Off

Problem: The PWR OK" and COM OK" LEDs on the faceplate are
off. This problem can indicate that the unit is not receiving the +5V
from the processor or Local or Remote Head, the 120 VAC or 24 VDC
from the external power supply, or both within the specified ranges.
This problem can also indicate that the power supply fuse (.75A or
.25A) has blown or that the module is malfunctioning.
Step 1. Stop any application programs or tasks that are running.
Use a voltmeter to measure the input power (120 VAC or
24 VDC) to the module. Verify that the power source is
providing 120 VAC or 24 VDC, whichever is appropriate.

5Ć1
 DANGER
VOLTAGE IS PRESENT ON THE PLUG CONNECTOR TERMINALS. DISCONNECT
THE POWER AT THE SOURCE BEFORE TOUCHING THE PLUG CONNECTOR
TERMINALS. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN
SEVERE BODILY INJURY OR LOSS OF LIFE.

DANGER
DO NOT TOUCH THE CONNECTORS ON THE FACEPLATE IF THERE IS POWER
ON THE WIRES ATTACHED TO THE PLUG CONNECTOR SCREW TERMINALS.
ALWAYS TURN OFF POWER BEFORE HANDLING A CONNECTOR THAT IS
WIRED. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN SEVERE
BODILY INJURY OR LOSS OF LIFE.

Step 2. Turn off power to the module. Verify that the input power
connector is connected securely to the faceplate. Verify
that the I/O Rail cable connections are tight at both ends.
Step 3. Turn on power to the module. If the LEDs are still off, try
replacing the I/O Rail cable. Check that the input
connector pins are not bent.
Step 4. If the LEDs are still off, turn off power to the module and
replace the power supply fuse on the front panel following
the directions below.

CAUTION
MAKE CERTAIN THAT THE ANALOG RAIL MODULE CONTAINS THE PROPER
FUSE FOR THE POWER SUPPLY BEING USED. USE A .25 A FUSE FOR 120 VAC
POWER AND A .75A FUSE FOR 24 VDC POWER. FAILURE TO OBSERVE THIS
PRECAUTION COULD RESULT IN DAMAGE TO OR DESTRUCTION OF THE
EQUIPMENT.

a) Use a screwdriver to release the fuse holder located on

the Analog Rail module faceplate. Pull the fuse holder
out of the module.
b) Take the old fuse out of the fuse holder and replace it
with the new fuse. Use a .25A fuse for 120 VAC power
and a .75A fuse for 24 VDC power. See Appendix A for
the fuse type and rating.
c) ReĆinsert the fuse holder into the module. Turn the
screwdriver clockwise while pressing down on the fuse
holder. The fuse holder must be flush against the
faceplate.
Step 5. Turn on power to the module. If both LEDs still do not
light, replace the module.

5Ć2
5.2 The COM OK" LED is Off
Problem: The COM OK" LED on the faceplate is off. This LED
signifies whether there is communication between the Analog Rail
and the host. The LED should be on if communication is taking
place. The possible causes of this problem are incorrect
configuration, a disconnected or malfunctioning I/O Rail cable, a
malfunctioning host, or a malfunctioning Analog Rail module. After
verifying that the configuration of the Analog Rail is correct, follow the
steps below to isolate the problem.
Step 1. Stop any application programs or tasks that are running
and turn off power to the Analog Rail module.

DANGER
VOLTAGE IS PRESENT ON THE PLUG CONNECTOR TERMINALS. DISCONNECT
THE POWER AT THE SOURCE BEFORE TOUCHING THE PLUG CONNECTOR
TERMINALS. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN
SEVERE BODILY INJURY OR LOSS OF LIFE.

DANGER
DO NOT TOUCH THE CONNECTORS ON THE FACEPLATE IF THERE IS POWER
ON THE WIRES ATTACHED TO THE PLUG CONNECTOR SCREW TERMINALS.
ALWAYS TURN OFF POWER BEFORE HANDLING A CONNECTOR THAT IS
WIRED. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN SEVERE
BODILY INJURY OR LOSS OF LIFE.

Step 2. Verify that the connections on both ends of the I/O Rail
cable are tight. Check that the input connector pins are
not bent.
Step 3. Turn on power to the module. The COM OK" LED should
be illuminated if communication is taking place. If the LED
still does not illuminate, turn off power to the module and
replace the I/O Rail cable.
Step 4. If applicable, try to reset the condition by disconnecting
and then reĆconnecting the cable between the host and
the Local I/O Head, the AutoMate Remote I/O Head, or the
DCS 5000/AutoMax Remote I/O Head. Troubleshoot the
host if necessary. If the problem is still not corrected,
replace the Analog Rail module.

5.3 Incorrect Data

Problem: The data (signal) being read is always on, always off, or
different than expected. The possible causes of this problem are
incorrect configuration, a programming error, a disconnected or
malfunctioning I/O Rail cable, disconnected or malfunctioning wiring
to the external hardware, malfunctioning external hardware or a
malfunctioning Analog Rail module. After verifying that the
configuration of the module is correct, follow the steps below to
isolate the problem.

5Ć3
 Step 1. Verify that the application program(s) is correct. Check to
see that the program is referencing the correct registers
(AutoMate) or symbolic names (DCS 5000/AutoMax).
In DCS 5000/AutoMax applications, make certain that the
program is not attempting to write to the input channels.
Step 2. Stop any application tasks that are running. Turn off power
to the Analog Rail module.
Step 3. Try to clear the condition by disconnecting and then
reĆconnecting the I/O Rail cable. Make certain the
connections are tight. If applicable, check the connections
between the host and the Local I/O Head, the AutoMate
Remote I/O Head, or the DCS 5000/AutoMax Remote I/O
Head. Check that the input connector pins are not bent.
Step 4. Turn off power to the external hardware. Verify that the
wiring to the external hardware is tight and functioning
correctly.
Step 5. Turn on power to the external hardware.
Use the Executive software to read the value on the input
channels. Use a voltmeter to read the input signal and
compare the two. If the signal is being converted correctly,
there is a problem with the external hardware or wiring.
Step 6. Troubleshoot the external hardware, the wiring, and the
host.

     

Problem: the underĆrange bit (12 decimal) on an input channel
register is constantly set to 1. Assuming that the power supply for the
external hardware connected to the input channels is providing an
input signal within the specified limits (0-10V), the possible causes
of this problem are incorrect (reversed) input signal wiring on the
module faceplate, a loose connector on the analog section of the
faceplate, or loose or malfunctioning wiring. Follow the steps below
to isolate the problem.
Step 1. Stop any application tasks that are running. Turn off power
to the external hardware connected to the module. Turn
off input power (120 VAC or 24 VDC) to the module.
Step 2. Verify that the 12Ćpoint connector on the analog section of
the module faceplate is securely attached to its mating
half.
Step 3. Verify that the signal wiring on the module faceplate is
correct. See step 9 in section 3.2 for more information.
Verify that the wiring is tight and functioning properly.
