I have 18 Ethernet/IP VSD's configured as generic ethernet modules. I had a situation today, where the VSD 'dropped' off the network, we replaced the ethernet cabling, and it came right.
We are thinking it could of been a couple of things:
What I want to know, is how can I determine if any particular node is offline?
I could code some sort of heartbeat I guess, but I would of thought that the node present status could be read via the software somewhere???

- The cable was faulty/damaged, long patch leads have been used.
- The RPI was too high (20mS), but when I changed this to 250mS, the problem was still present
