Hello We have a Siemens S7 - 300 with 2 Profibus Ports with 4 Remote IO (Wago) and OP 270. The CPU and all remote IOs have Bus Fault and also SF on the CPU. The 4 remote IOs are connected to Port Interface 1 and Operator Interface to Port Interface 2. The OP has a two sided profibus connector. I need to connect PC to the system for diagnostic but both Port 1 and 2 are occupied. I tried to connect the PC to the 2 sided connector on the OP but it detect 1 node and request to provide rack and slot number but can't access the PLC. Can I connect the PC to the 2 sided profibus connector on the OP. If yes, what PG/PC address should be configured (usually 0). Theprofibus termination should be set to ON or OFF. I'm confused. Any guidance would be most welcome regarding the connection to the PLC of the PC for the diagnosis. Thanking you in advance. ------------------------------------------------------------------------------------------ |
