I have Siemens S7 200 CN micro plc and connected to SIMATIC OP77B hmi through MPI/DP . The communication shows error , and all the values in the HMI shows ####. I checked all the cables of the communication between HMI and PLC and shows healthy. They are connected acress in the DE 9 connector at the pin no. 3, 5 & 8 on either side without cross connection. The baud rate selected is 187.5 kb and the address is "1" and there are no other devices connected in the system except these two devices.
Please help me to get the things resolved. ------------------------------------------------------------------------------------------ |
