How do you let your app know the LAN's down?

[Niel Craig]

I am developing a distributed control system using FP-1600. I have set up the watchdog timer to put the FP modules into a safe state in the event of the LAN going down. That works fine. My question is - what is the best way to enable my app to discern that the LAN has gone down? I would like to stop it trying to run tests over the LAN if comms have been lost and flag the user that there is a problem.

Thanks,

Niel.

When using the FieldPoint VI's with a FP-1600, you will receive error code 33163, "The connection to the module has been broken" whenever the FP-1600 is offline (due to network failure, wrong IP address or the power to the FP-1600 being removed). You can look at your FP Read.vi, FP Advise.vi or FP Write.vi and check the error cluster for that particular error code.

Thanks Aaron. That's just what I needed.
