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 ?
