Separate communication loops for each device?

[David99999]

Just wanted to see if I'm on the right track. I have about 4 separate devices that I speak to via ModbusTCP with a compactrio. 

I'm assuming each device needs it own loop, because if they were all in the same loop and communication dropped out on one, I would cease to be reading any data from any device until the comm timeout finished. Yes?

No, you can read all channels from one reentrant VI. Don‘t have to wait for timeout, just read data if there is some.
