I need to to update an old (2012) monitoring system which is based on a legacy cRIO-9073 (https://www.ni.com/en-us/support/model.crio-9073.html). This component will not be replaced.
The original system reads 25 4-20 mA signals (plus a few more channels in either analog or counter mode). Each of the 25 sensors needs to be replaced with a serially connected device (RS-485). To interface them, I plan to buy an Ethernet Serial Server. The cRIO is supposed to poll the 25 measurement values at 1 Hz using TCP or UDP.
Does anybody is experienced in networking with cRIO devices? Should I expect poor performance or other communication troubles?

Hi Paolo,
I used the cRIO907x line for some time and usually they were quite ok.
You need to care about available RAM (it only has 64MB RAM!), I usually installed only the NI software components really needed for the job and nothing else/more.
Handling 25 sensors, connected via one Ethernet device should be ok.
