Old Fieldpoint controllers not talking to our 2023 Q3 front end software through TCP-IP

[ScottSanville]

Hello all of you Fieldpoint people out there!

We have run into a Fieldpoint communication issue while migrating our front end software from 2015 to 2023Q3 for a windows 11 site upgrade.

We have two sets of fieldpoint controllers. The 2200s are running a 2015 software version and we are having no communication issues with these. Then we have about 6 older units (2110s and 20s) running a version called 8.5. On these older controllers, we can see the controller in max, but we can't see any of the temperatures, flows or reservoir level that those controllers monitor.

I was wondering if anything changed in the IP protocols/communication between 2015 and 2023Q3 that could be responsible for bricking our stands?

Thanks in advance for your thoughts and consideration.

-Scott

According to this overview you should be able to run LabVIEW 2015 on the cFP-21xx controller too.

However support for NI Fieldpoint in newer LabVIEW versions than 2015 SP1 is not documented to be available.

So the question is then if you have your own TCP/IP protocol implementation to communicate from your LabVIEW 2023 application to the LabVIEW RT application on the (c)FP controller. NI Fieldpoint itself is not supposed to work in anything newer than LabVIEW 2015 SP1.

If you use your own TCP protocol using native LabVIEW nodes, you will have to do some source code debugging I'm afraid.
