We are using 2 Nos. FM 350-2 (6ES7 350-2AH00-0AE0) in one of our project where we have toprovide channel redundancy. We are getting two inputs from a single speed sensor which we have connected to2 FM's module i.e.1st input to1st FM & 2nd input to 2nd FM. Now, we have to create the redundancy in such a way that if 1st input fails then we have toread the 2nd input.

For this, we need to read the hardware diagnosticsof FM module. we trieddoing this using themanual but no success.

Can anybody help me ?

Do anyone have sample program?

Thanx in advance ..........


sm

The function DIAG_RD can only be called in the interrupt OB82.

The FC DIAG_RD executes the following actions:

Reads 16 bytes of diagnostic data from the FM 350-2 Enters these data in the counter DB in

the data area DIAGNOSTIC_IN_INFO. These data contain the diagnostic status of the whole

module (covering all counters).
