Communication error in multiEtherCat system

[erevan]

Hello all

I have a system, which hardware consists of NI cRIO 9025 and four NI 9144 expansion chassis, which are connected in serial by Ethernet.
If communication error exists between items( between controller and expansion chassis or between expansion chassis and expansion chassis)
our software returns error but doesn't give information where exactly communication error exists. How I can know where exactly communication error exists?

It depends on what the error actually is. If you remove a cable or power from a 9144 you should see a error number in your variable error output.
