Hi,  
I have a robot with 1125-2 SafeMove PRO option but I don’t have the 841-1 Ehternet/IP option as I used to in the past. Instead I have the Anybus option 840-1, would I still be able to use the safety over CIP or do I need to get the 841-1?

Just in case anyone is looking for the same thing, yes you need 841-1. 840-1 Doesn’t support safe IN/OUT’s
