force in labview the variables of a PLC

[Maiki]

Hi,

I want to make a simulation in labview. I have a PLC connected to labview through OPC. I have a lamp and a switch in the front panel in labview and I want to click the switch to force the input in the PLC and the PLC, due to the program that it have inside, will activate the output that will turn on the lamp, in Labview again. This first simulation is very simple but then I want to make a more complex simulation. I have the simulation on the computer but the PLC as a hardware. I know that I can force the variable with the Step 7 MicroWin but I would like to know if I can force the variables in the PLC through Labview.

Thanks,

Maiki

I think you ve to use the Shared variables to send the PLV variables to LV, using the Shared Variable Engine & I/O Server communication meant for OPC in LV.

Do you have the LV DSC module?

Actually I'm evaluating the program, I don't have Labview DSC. I'm using OPC through Data Biding, not through I/O Servers. Can I do what you say with the evaluation software? or I need to use the module DSC? The point is that I want to be sure that it works before buying the program.

Thanx

I think you will have only the OPC client in the LV Evaluation version.

Please contact someone at your local NI office to get a clear picture.
