Hello all. I am purchasing a CompactLogix to use as a server which will host 4 other PLC's (2 ControLogix, 2 Beckhoff) and a Fanuc RC. The current system has safety mats with individual Sick Safety Modules. This server PLC is going to be controlling the robot using inputs from each of the PLC's in this network. Finally at my question, when does one need to use a Safety PLC as opposed to a non-safety rated PLC? I am thinking because all I am doing is adding a robot to this system, and the system already has machines with machine safety in place, a standard (if that's the correct word) PLC should be fine, right? Also, I don't really need any I/O points for this PLC since it will all be E-net IP. I think I would like some embedded discrete I/O just for gits and shiggles. I know I need a hot rod processor with horsepower but not a lot of memory. I am hoping someone who has integrated a robot with existing PLC's might be able to recommend controller for me. Thanks in advance.
