Read I/O values from an entire C Series module from Ethernet Rio

[Dhomfray]

With a single CompactRIO I read all the thermocouples from a module by doing this

I have added a Etherent RIO full of thermocouples as follows:

In my untitled1.vi I would like to do a similar thing as the top picture but pointing at a module on the NI 9148. I would imagine it is a PSP thing but have tried for a day with no luck. Anyone got a clue?

cheers

Hey Dhomfray,

Have you tried using Network Streams? 

In this configuration you are trying to read I/O which in on another RIO. To do this you need to:

1. Read the value on the Ethernet RIO.

2. Put it on a Network Stream (Write).

3. Read from the Network Stream on the cRIO.

Check out here how to use Network Streams: https://www.ni.com/en/shop/labview/lossless-communication-with-network-streams--components--archite....

I won't take you more than 30 minutes to make it run 🙂

Good luck and keep us updated! 

Cheers,
Bozhidar

Did have a look at that method but it was a problem of knowing when the data set was created. I would like a method of collecting data from both the primary compactRio and the EthernetRio at the same time. Its a shame there is not an easy method of just collecting the whole module using a similar method already used

Hello Dhomfray,

The goal of the application is to read data on different modules on different devices away from each other. However, simplified, it is usually not a simple process. 

Have you checked this one: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x4LaCAI&l=en-US

Check the last figure how the VI is configured and give it a try.

Best,
