We have an S7 313C CPU that was gathering dust on the shelf, so
I decided to put it to good use as a training/demo PLC. I powered it up, installed a new mmc card and....... nothing. I cannot get
connected through the MPI port.
There are no error lights only the power and 5volt lights are on, and they are both green. I have performed a memory reset per
the manual, checked baud rates, checked MPI addresses.
I can change the processor from RUN to STOP by the switch on the front panel, but that is about all that I can do. The error
message that Simatic manager shows is:
" 33:16944 Online: Cannot find active partner. "
Or something very similar to the above phrase. I am sure the
numeric error code is correct.
Anyone have any ideas as to what I can try next??
