Is there an equivalent to the Fieldpoint Publish VIs for cRIO?

[russellb]

I am migrating an existing system using Compact FieldPoint to CompactRIO. The current code takes advantage of the green Fieldpoint Publish VIs.  Is there an equivalent technology for cRIO or does anyone have a suggestion for a replacement technology?

Hey Russell,

You could use NI-Publish Subscribe Protocol (NI-PSP) variables. You host them on the 'server' (which could be either a cRIO or a PC) and can read/write to them (acting like a client) on either. This publication gives a wealth of knowledge on PSP variables: https://www.ni.com/en/support/documentation/supplemental/22/buffered-network-published-shared-variab...

Have a nice fall weekend,

Thank you. We are trying not to use shared variables because we had reliability issues with them on this same system in the past.

Hi Russell,

I'd recommend looking at Using the Right Networking Protocol to help match a protocol to your application. Based on what you've posted so far, it sounds like the application might match to UDP or TCP. Here are two resources on deciding between UDP and TCP, if you decide to go that route.
