SMS Control in WAGO PLC 750-8207

Hello everyone,

I’m working on a project using a WAGO PLC (model 750-8207), and I need help implementing SMS control for memory bits.
Goal:
I want to be able to send an SMS to a SIM module connected to the PLC, and based on the message content:

  • If the SMS says ONM0, it should turn ON memory bit M0.
  • If the SMS says OFFM0, it should turn OFF memory bit M0.

If anyone has:

  • An example program/code for this,
  • Experience integrating SMS communication with this PLC,
  • Or any guidance on how to parse SMS and control memory bits,

I would be very grateful for your support.
Thank you in advance!

Best regards

Are you using Codesys 2.3 or e!Cockpit ?

I am using e!cockpit

I have this old sample program but unfortunately I don’t have any information about it:
SMS_8207_Simple_SMS.zip (215.6 KB)
Inside the library you have good information about the used function block.

Thank you very much for sharing the sample program. I’ll check it out and see how things go. If I get stuck or need help, I’ll definitely reach out.
