watlow ez-zone-RM

[Jonnynumber5]

I am a beginner to this, and need help! I have an ez-zone-rm (actually a lot of them) hooked up to heater tape, and I need to control them all simultaneously. I have an example program for them, but it only controls one zone and one instance at a time. Is there a way to program some kind of loop to change parameters of more than one instance and zone all at once?

THANKS!

I forgot to include the example program...here it is!

Yes.

Was that it? 

Essentially you need to change the controls on the front panel to arrays so you can set the parameters on a zone/instance basis. I'd suggest using a table that has 3 columns: zone, instance, parameter. If the "write" value is supposed to be different then you can make it a 4th column. In the "Write" state you can autoindex the table to peel off each row, and then get the individual values. Same thing for the read.

To learn more about LabVIEW it is recommended that you go through the tutorial(s) and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.

Thanks for the advice! I made a very sloppy program out of the example, but it works!

 

Now I have a new problem at hand. I want to get live-time data from my temperature sensors. I tried to make some sort of loop with the que system that already exists, but it would only que a few times. Is there a better system that you could suggest for that?

I have attached the program that I have edited.

Thanks
