I have an old PLC5 program with block transfers for many A/I cards. The "setup screens" won't come up because the modules were never added to the IOC. I believe it was set up long ago by entering the scaling and other values in the N7 registers. I can't find documentation on those BTW registers. I want to adjust scaling. BTR - R2/G6/M0 Control N7:10 Data N7:40 Len 20. BTW - R2/G6/M0 Control N7:15 Data N7:80 Len 37. Also, the BTR and BTW execute at the same time...which seems odd. Shouldn't the BTW be on 1st scan, or when I trigger it somehow? Thanks!!
