HiNavnag,

I'm faceing the same issue. Did you find any solution for this?

Hello friends

We are using S7-300 ( CPU 315-2 PN/DP ) in a networked system. ALl the CPUs are receiving time synchronisation signals from a NTP CLock server.

We have configured the NTP Server IP address in the Hardware configuration of the CPUs and update time interval of 10min. The Clock is getting synchronised normally.

However the customer wants us to generate an alarm in S7-300 if the Time synchronisation has failed since a certain duration. e.g. if the NTP clock has failed or due to network failure, if the clock is not getting synchronised ( For say 1 hour ) , then an alarm should be generated .

Is there any way of generating such an alarm ?( Any Error OB , SFC or SFB that can be used )

Thanks
