Dear all,
I'd an issue related to Siemens S7-300 with a 315 CPU. The CPU has a ProfiBus cable connected and I attached my MPI cable to the socket to CPU and successfully downloaded the Ladder logic diagram to my laptop, but the problem appeared when I tried to monitoring ONLINE with CPU, a message of "Unable to reach the module CPU 315-2 PN/DP via the online interface".
So, what could be the reason ? and how to fix this ?
Thanks.
