Right, you will only need rack optimization if you are remotely controlling I/O modules I think.
Now I am adding the PLC #1 CPU into the PLC #2 I/O config. I was able to add the ENBT just fine but I cannot add the CPU at major revision 21. It only lets me go as high as 20. I suspect this is because of the low firmware version on the ENBT. I think I will probably have to flash it in order to get 21 available. Is this correct?
