Hi Everyone,

I have a problem with several safety cards F-DI on  an ET200SP. The light on the card change when i push the emergency stop button , but  the input don't change in the PLC. This problem happens on several FDI card.

The ET200SP have a special configuration: DI-DQ-FDQ-FDI-DI-DQ-FDQ-FDI

If someone met already the same problem or have any idea to resolve it.

(On the attached image, the ET200SP is in fault because the next PN module is not reachable.)

Thanks

Finally i find the solution: It is because the input didnt not used in the program

F-DI inputs not showing on program - 156508 - Industry Support Siemens

Hi,

and the direct link to the FAQ:

Why does the status of fail-safe inputs and outputs not change in the watch (monitoring) table?

regards
