Control and Simulation Software for G (GSIM)

[DonTan]

I am currently programming a PID controller using a Siemens PLC. I have installed LabVIEW DataLogging and Supervisory Control Module which allows LabVIEW to interface with my PLC.

Would appreciate if you could advise if it is possible for the PLC PID controller to control a first order process model created using LabVIEW GSIM through LabVIEW DSC? Please email me at pwdt2002@yahoo.com if you could offer me any advice or assistance.

Merry Christmas and a Happy New Year.

Best regards

I haven't really played with the GSIM toolkit but you should be able to use it with DSC just fine.

The PID Controller inputs and outputs (set point, process variable, error, and the P, I, and D terms) could now be Tags in DSC (they don't have to be). So, what you need to keep in mind when any of these values is a Tag is to use the Read Tag VI and get the value before using it as an input in the PID Controller. And you would use the Write Tag VI to write the Outputs from the PID Controller to the DSC Engine for it to be processed for the rest of the system.

Hope this helps.
