Hi

Need to know if there is any way to send out a watchdog signal from Bently Nevada communication card /92.

Background

In our normal setup we connect the BN/92 card direct to our plant bus (with Modbus TCP/IP).
Our Modbus block in pcs7 will then send out diagnostic error.

In this project we were not allowed to connect the BN/92 to the PB (Large Multi proj).

So we solve it with an Any bus converter: Modbus TCP/IP to profibus.
Problem now will be that we can’t verify if the bus goes down. Trying to solve it with process logic like turbine running and 0 in vibration will activate diagnostic bus alarm.

Its work but it will not handle situation with keep last good value.

Is there any function from BN3500/92 to send out a watchdog signal to PCS7?
