ktp700 basic with profibus dp +S71241 CPU+CM1243-5

2 posts in this topic


I'm new to Siemens and now working on a project for my client. I have a S7 1241 cpu,  CM1243-5 com module, a KTP700 hmi prifibus dp.

The hmi is connected to the CM1243-5 via profibus cable.

My problem: I'm not able to detect the hmi. My plc is connected to my router and I'm able to get online with it. 

I've attached some diagrams..just in case.

Appreciate any help.

Please check the properties of your CPU.

Go to tab 'Communication'

Check if there are free resources. Perhaps there are resources reserved for S7 Basic communication.

Try to lower these, download hardware to CPU and check if KTP700 HMI will communicate.

Best regards,
