For reference with an external data system that will be temporarily installed at a customer's site, they have asked that I tie into their data network to record data from their control system. They apparently use a reflective memory network for data sharing. I have no prior experience with reflective memory, but all references to it involve real time systems. I do not need absolute determinism to acquire this data, I can be late by several milliseconds with no problem. Do I still need to use LabVIEW Real Time to interface with the PXI reflective memory node?

Hi AEI_JR,
What PXI system are you using in your application? Also, what software are you currently using?

Jordan,
Thanks for the reply. The only module I have researched is the GE cPCI-5565PIORC. I have no prior experience with reflective memory, and the system has not yet been built; I am trying to design one to meet my customer's need. I plan to write custom software in LabVIEW that will simultaneously collect dynamic data and poll the customer's reflective memory network.

Hi AEI,
I have worked with that card briefly before. It has a Visa based driver and RT isn't required. However, I haven't worked with the card on a non-rt system and am not sure if there any issues to be aware of.
A lot of work has gone into integrating support for the card into Veristand, it may save you enough development time to use at an RT-Veristand system to be worth the extra cost.

Thanks. I have sent an email to my local NI technical rep asking for help with this application. Being that I would be trying to distribute a system with three unfamiliar pieces and no way to simulate locally, I'm going to have to work closely with someone that knows what they're doing.
