Hi All,

I am looking for system bits indicating if a digital input board located in an ET200 gets external power supply.

I found a description of SFC52 where they talk about "diagnostic bit 5: no sensor power supply" but very little explainations on how to work with that diagnostic buffer.

Did anybody ever found a technote or sample code about that ?

Regards

Antoine
