I do need CIP safety as I have a bunch of robots in the line. My SL5500 (Customer Spec) is directly connected to the NX102. So you are saying the safety IO cards attached to the EIC202 would not work? I was thinking of putting a mix of standard and safety IO together on the EIC202 so that I could save up on space and modules. But if the SL5500 would not acknowledge the safety IO cards via the EIC202, then maybe I need to get the GI-S series safety modules instead, to wire up field safety.
