I have a machine that is running a SLC 5/03 with medar/wtc welding cards in it. I need to upgrade it to CLX for motion control reasons. It is currently using ultra3000i drives, but I am out of index positions on a couple of axes. Do any of you have any experience with using medar cards in a remote SLC rack that is slaved to a CLX? I plan to use a 1756-DHRIO and a 1746-ASB for the COMMS. Any advice/comments appreciated.
