When there is network traffic on the TCP/IP layer, the ping command response time
varies and may cross the specified limits as the priority is in the I/O and GOOSE
functionality.

Troubleshooting inactive I/O modules

If a valid configuration has been downloaded in RIO600 but the Ready LED of the I/
O modules remains off, check the connections between the physical modules. The
Ready LED on the binary modules remains off until the configuration is applied.
In the newer modules, the Ready LED flashes indicating that the module has been
powered up but the configuration is missing.
1. Separate the modules from each other.
If the modules are loosely connected with each other or the back plane pins on
the modules do not connect exactly between the two modules, the I/O modules
are not detected by the communication module. Thus, the configuration is not
applied.
2. Reconnect the modules.
The configuration file is applied after the LECM module verifies the type of the
modules and its position which is downloaded in the configuration file along
with the physically connected modules and their positions. The lit Ready LED
(green) indicates that the configuration is applied.
