I want to implement an HMI on a TPC-2230 that will be connected to a CompactRIO-9030.
I've been reading in the forums that the proper way to do this is through Shared Variables.
Naturally, before implementing the complete HMI with all the n variables I intend to control from the TPC-2230 to the CompactRIO, I want to make sure that the basic operation of the Shared Variables is carried out successfully with a very simple example.
This is what I have done so far:
1- I installed the Run-time Engine 2017 SP1 (32-bit) in the TPC-2230 and LabVIEW RemoteDevelpment 2017. (I'm using LabVIEW 2017 (32-bit) on my Computer and cRIO)
2- I created a new project
3- I created a library with the variable "control" that I am going to share between the two devices.
4- I create two VI within the project:
- Main_Computer.vi: Contains a while loop where a waveform chart receives the value of the Shared Variable "control".- Main_TPC.vi: Contains a while loop where you have a numeric control that sends the value to the Shared Variable "control".
5 - I executed both VIs, effectively, the variable is shared among them and the changes in the waveform chart are reflected.
6- Then, under Build Specifications -> New -> Application (EXE), select the VI Main_TPC.vi source. And in the "Shared Variable Deployment" tab, I check the "Deploy Shared Variables at application execution" option.
7- Once compiled, I send the folder containing the executable to a directory of my TPC-2230.
8- I run the executable in the TPC-2230 (here I get a deployment dialog, which is carried out successfully).
9- I run the VI Main_Computer.vi from my PC.
Unfortunately, when making changes in the Shared Variable in the TPC-2230, you don't see the changes reflected in the Vi that runs in the computer.
I already did the following verifications:
1- The two computers are in the same network
2- I can ping between them from the Command Prompt
3- I already verified that the "NI Variable Engine" service is running in both teams.
And well, that's all I've done. I thank you in advance for all the help you can give me.
Pablo.
