Hi All
I have a problem with my Siemens S7 PLC
I can't seem to go online to it. The message given is 'no other active partner found'.
Background:
There's a pro-face HMI connected to the PLC via its MPI port. There was an error on the CPU: The EXTF & BUS1F LEDs were lit.
In order to make these LED's ok I restarted the PLC, and the LEDs were ok then.
But then I could no longer go online with my laptop even though I have not made any changes to the configuration!
any suggestions?
