When I increase the ReadData or WriteData array sizes in my program, all of the configuration parameter values go to 0.

Article Number: 33 | Rating: Unrated | Last Updated: Wed, Jul 9, 2014 at 9:41 PM

When controller tag array sizes are changed in the ControlLogix platform, RSLogix5000 re-initializes all of the tags within that data type. This sets all values to 0 in all tags within that group. Before changing any controller tag array sizes, the user should record all configuration parameter values, and re-enter those values after the array size has been changed.

I was not using both Modbus ports on my MVI56-MCM module, so I set all the port parameters for the unused port to zeros to disable the port and now my module is faulted and will not restart. Why?
