Special care must be taken when defining the files for the side-connect interface.
Because the module directly interacts with the PLC processor and its memory,
any errors in the configuration may cause the processor to fault and it may even
lose its configuration program. After defining the files and populating them with
the correct data, download the program to the processor, and place the
processor in Run mode. If everything is configured properly, the module should
start its normal operation.
If all the configuration parameters are set correct ly, the module’s application LED
(OK LED) should remain off and the backplane activity LED (BP ACT) should
blink rapidly. Refer to the Diagnostics and Troubleshooting of this manual if you
encounter errors. Attach a terminal to Port 1 on the module and look at the status
of the module using the Configuration/Debug Menu in the module.
