Thanks alot! I encountered 1 more question regarding FDI-signals if you got time to answer that. I assigned the signals and tried using the Failsafe safety function ""EV1oo2DI" and got the following error. I had the channels assigned as 1oo2 in the card configuration and changing the configuration to 1oo1, the error is now gone and can be compiled. The signals i try program are from a emergency stop button, where 2 signals from the same button are used to cause a shutdown (ES01A and ES01B). The goal is that if either of these signals is 0, the evaluation should change from TRUE -> FALSE. Should the channels be configured as 1oo1 or 1oo2?

Hi Aleksi, You can use the external sensor-supply. have a look into the S7-1200 manual. In chapter 4.1 you see the digital input applications. SIMATIC S7 S7-1200 Functional Safety Manual hope this helps, regards, |
