How to connect more than two SM1281 to an S7-1200 PLC?

Hello everyone,

I have successfully connected and loaded the vibration data into the SM1281 and S7-1200 based on the Siemens demo program.

However, I am now facing an issue. I need to connect nine vibration sensors, which means multiple SM1281 modules need to be connected.

I followed the SM1281 manual and modified the demo program, but the manual is too brief that I was unable to connect successfully.

Is there any program or more detailed resources available regarding how to connect multiple SM1281 modules?

Thanks.
