Hi guys, new to the forum due to having problems on a new system of course. Looks like a lot of good info on here, but can't find the elementary stuff I'm looking for so here goes. My company just transitioned from an old Honeywell LM 620 to the RSL5K. Our program was built and installed for us by a third party so my knowledge of building I/O is limited. We have just installed two new valves and I am needing to build outputs to open/close them and inputs from the valve limit switches. I am trying to build this logic offline and it is not letting me assign the field I/O addresses. Does this have to be online, and if so, can I only assign card points as I am building or can I build the points first, add logic and then insert into rungs? I had some basic level 1 training,ControlLogix Fundamentals and Troubleshooting, but there was nothing regarding building/assigning I/O. Any help is much appreciated.
