Hello All,

As i am new in PLC programming, i was simulating plc programming. There was the error, which says "Module is in operation STOP MODE". When i have run the PLC hardware diagnostic, i have found the CPU order number is differ, which i assigned in HW configuration  i.e 6es7841-0cc05-0ya5 is showing in order number, instead of 6ES7 313-5BG04-0AB0. 

Also there is 3 event which was showing in diagnostic buffer i.e 16#530D, 16#430E & 16#4309.

Previously, it was working fine.

Can you please help me out on this?

Closed cause question posted twice.

The second thread with the subject 6es7841-0cc05-0ya5 is showing in order number is published within the conference STEP 7 Additional Software.

Best regards,
