1756-RM

I am starting to set up a redundant PLC system. I have read the manual for the 1756-RM module but can't see the answer to my question. When i config the controlnet network do I put the two racks on the network layout or not. My guess is not but I thought I would Ask.

The primary and secondary chassis should be identical based on the Safety Reference Manual - Using Control Logix in SIL2 Applications. Publication 1756-RM001F-EN-P - June 2009. My point of reference is Chapter 1 page 20. I have two on tap to program, I have been advised this is the way to go if you are SIL2 rated or not. I'm no expert, but you get what I've experienced so far! I do believe the RM module does all of the configuration for the secondary CLX. good luck Edited 21 Jul 2010 by semilogical
