[Dsg-hallc_controls] Upgrading HMS controls

[Brian Eng]

Those are the firmware versions that run on the respective modules. They don't need to be the same number.

20.058 is for the controller and 20.009 is for the redundancy module. They just happen to start with 20, the ethernet module is running 11.001 and the controlnet 25.005 for example.

The controller must start with a 20 to support RSLogix v20 and the 058 part is the latest firmware that supports redundancy.

Basically to support the redundancy functionality Rockwell has a list of firmwares that are compatible and 20.009 was listed for the RM2 so we downgraded that which allowed it to work (previously it had an error about needing to upgrade application software).

Since the PLC system is running fine, it does not seem like the second fiber cable is required to run. You mentioned that you would look into submitting a PR in for a second fiber cable to be able to clear the LED indicator on the modules.
