encountered, an error code will be displayed on the
sevenĆsegment LED.
If the green status light is off and no sevenĆsegment error
code is displayed, a local watchdog failure has occurred.
If diagnostic fault codes 0 through 9 or b are displayed,
the Remote I/O module must be replaced. Refer to
Appendix D for a description of the error codes.
If the thumbwheel switches are set to an invalid drop
number, the A" fault code will be displayed on the
sevenĆsegment LED on the module faceplate after
powerĆup. To clear the invalid drop number fault code,
refer to chapter 6.
Step 8. If you are connecting the module to a fiberĆoptic network,
go to step 10. If you are connecting the module to a
coaxial cable network, continue to step 9.
Step 9. To connect the module to a coaxial cable network,
connect the drop cable to the Communications Passive
Tap (M/N 57C380). Note that the end of the cable which
connects to the passive tap is labeled TAP."
Figure 3.1 shows the Remote I/O module connected to the
network. Continue to step 11.
Step 10. To connect the module to a fiberĆoptic network, refer to
figure K2.2 in Appendix K, and connect the drop cable to
the transceiver. Continue to step 11.
Step 11. Monitor status registers 15 to 18 of the drop 0 area in each
module using the Status command described in chapter
5. If the values in these registers increase consistently over
a short period of time, there is a communication problem.
Refer to chapter 6 for instructions on troubleshooting a
communication problem.
Step 12. Verify the installation by connecting the programming
terminal to the system and running the AutoMax
Programming Executive software.
Stop all programs that may be running.
Use the I/O MONITOR function. If the module is in the
local (master) rack, enter the Remote I/O module slot
number. Enter 4 (status register) for the register to be
monitored. The value displayed should be 1 in every bit
that represents a drop that is communicating with the
master (1Ć7).
If the module you want to monitor is in a remote (slave)
rack, enter the slot number of the master Remote I/O
module, the Remote I/O drop number (1Ć7), and the slot
number of the Remote I/O module in the remote rack.
(also called the remote slot). Enter the data register to be
monitored. The value displayed should reflect the status of
the register. Toggle an input or output and verify that its
status is reflected correctly in the register.
