Dear experts,
Recently we installed a new control which is using Allen Bradley PLC5/40 (1785-L40B) (redundant processor & IOs).
During the project phase, the logic inside the PLC (downloaded by someone else) was accidentally wiped out.
I tried to use our pramming terminal but failed to communicate. RSLinx did not detect any PLC. We are using PCMK card. I've tried to access other existing PLCs with the same PCMK card and OK.
I noticed that there were two DIP switches at the back of the PLC. SW1 & SW2. Was it because of this DIP switch configurations? It (sw1) was set at MSD = 0, LSD = 0, Baud Rate 57.6Kbd. What configuration should I set for PCMK? Thanks.
