LabView application for Watlow RMC Temp Controller

Hello,

I'm trying to program the labview to control RMC Watlow ez-zone, through the USB/RS-485 adapter.

in its example (driver downloaded from https://www.watlow.com/products/controllers/software/labview-driver-software ) it can initialize controller, Read and write input parameters. My application have 4 zones, so the controller also have 4 inputs, I want to have a program to read at the same time the input parameters, How can I read 4 thermocouples values from the four analog inputs? Also if I want to change 4 temperature set point how I can do that.

 

I appreciate your comments or help you can provide me.

Hi CoronaReynosa!

Once you have installed the driver, you can read the 4 inputs using 4 controllers in your LabVIEW code.

Here is an example i just downloaded from Watlow, about how to configure the LabVIEW interface in order to read one input. Now you just have to modify it in order to read the 4 inputs.

Hi Limas

Thanks for your answer and VI you uploaded, unfortunately I have LabView 2015 and I couldn't open the VI. Can you help me saving the file to previous version?

Hi CoronaReynosa. I attached the folder with the VIs you need.

Im not really sure but I think that if you have installed the driver, there will be some files in you hard drive in C:\Program Files (x86)\National Instruments\LabVIEW 2015\instr.lib\Watlow Std Bus\Public

Those files are the same that i am attaching here. I'm telling you this because maybe when you open the file called "Standard Bus LabVIEW Example" a browser will be launched and you will have to select those files in order to open the VI.
