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 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.
