Good night,

I'm using the AI 1231 TC card with a S7-1200 Safety CPU.

The 6ES7231-5QD32-0XB0 card is faulty and does not allow the PLC to start.

We changed the card power to directly from the source.

Unsuccessfully..

 Hello kleberfalcao;

There are participants on the Siemens forum from many countries, many do not speak Portuguese.

We gave chosen English as a common language, plese respect that and write to us in English on your next visit.

Hope this helps,

Daniel Chartier 

hi kleberfalcao,

did you look online what the CPU is complaining about?

Did you check the correct connection between the modules?

Please also explain exactly how the station is wired.

regards,
