I have the problem of creating an RFID login to my system.

Equipment I am using:
- CPU S7-1200
- Communication unit RF120C
- Read only RF1070R
- reading cards
The purpose would be to create a system where the user logs in by using RFID card.

Is there an example project available that I could use? Now I do not have clear idea how I should start. I am using TIA portal v.19.

Thanks for the help

Hello Kokeilija

Yes, there is an example: 

Logging User Data by means of RFID with the SIMATIC S7-1200 (Set 13)

Also, you may find useful the next manual:

SIMATIC Ident RFID systems Communications module RF120C with application blocks for S7-1200 and S7-150

Hope it helps 

Thanks. I will check those out.

I forgot to mention that I am using MTP400 HMI as my user panel.
