Hi there and Season's Greetings to all.
It's been a few years since I connected to a slc/pv combination via rs232 and it's all gone with the wind. My setup is: slc 5/03 and a pv550. So, the slc has 232 and 485 conns, and the pv has the same. Comms to the slc ok via usb/serial, using 1747-cp3 cable. The slc/pv connection is via an AB moulded DH485 lead. I'm sure I remember a pass-thru option in the comms setup for one of them, but maybe I'm confusing it with omron (which does have that option). I used auto-config in rslinx with the slc connected and got the "AB_DF1-1, DH485" driver, which runs ok. When the pv didn't show up as a connected node in the pb download screen, I tried an rslinx auto-config with the cp3 plugged into the pv, but no go. So... Which bits have I forgotten? Thanks for looking at a dumb question.
