Hi all, Currently we have a setup with groov epic as main controller and groov rio as remote io. We have pid loop running for temperature and humidity in groov rio.
What if the groov rio lost its communication from groov epic? (Ethernet cable disconnected) When I disconnect the groov rio the pac control stops running stating no response. The only way to control the groov rio is using groov manage? or nodered?
And the PID will keep running with the Ethernet cable disconnected.
No need to control the RIO as such when the network is down, but it depends on what else you have going on in the EPIC driving the RIO outputs… But in short, the PID loop will keep running no problem.
Your question has been well answered in this thread. I think you and your co-workers would get a lot of out reviewing it:
The RIO has a two port switch, put a fixed IP in a laptop or PC and plug into the second RIO port, watch the PID and I/O when the Ethernet is plugged in, then pull the main feed into the RIO and you will see exactly what happens on the laptop when the main Ethernet is unplugged.
