Hello everybody,

Currently, I'm working with a CP 313-2DP (6ES7313-6CE01-0AB0), and I want to add RFID read, write functionality, using an RF166C (6GT2002-0EE20).

I tried using the ident profile for S7 v5.5 and the standard libraries from TIA, but the size of the FB1900 Ident_profile is too large. The CP has approx. 32kb of work memory, and that FB alone takes up to 20kb.

I tried to use the FB45 Wizard also, but the component RF166C was not available.

I'm thinking of using the functions X_PUT and X_GET as a replacement, but I'm not sure how to configure the 'Operation Mode' or if this would be the right approach.

Do you have any suggestions or alternatives?

Thank you in advance for any response!

Have a great week!
