SLC multiple racks into 1756 (DH)RIO
BourneToRide posted a topic in Allen Bradley / Rockwell Automation
I am converting a multple rack SLC project to CLX and as a fist step I have to keep the SLC racks while converting to CLX processor. There is an existing CLX rack with 1756-DHRIO card talking to other SLC over DH+ and i thought it would be fairly simple to connect all the 8 SLC racks via the RIO channel. Except the first rack has 2 extensions with zero spare slots, where i was considering 3 x 1747-ASB, now can I use single ASB in slot 0 where SLC resided to connect to all 3? Same with another rack already on RIO, the first rack has ASB installed but the extension has no spare slots. The documentation I have suggests I can only address 8x 16 bit cards on each rack, or have i got that wrong, most of my cards are IB16 or OB16, just the very first rack has analogs. Is the 1756-RIO card any better at addressing 25x 16 way cards as 1 rack
