Hello Everyone,
I need assistance in developing a LabVIEW program to operate an OP3 Relay Module of an EPC3004 for automatic heating/cooling changeover applications.
I have an experimental room fitted with a glycol system with a heating and cooling circuit. The EPC is supposed to control a valve that feeds the glycol system with heat/cool water depending on the test demand. iTools works fine, I just change the value of the output from 1.00 to 0.00, and the valve opens. But I am a bit confused about controlling the output OP3 in LabVIEW.
Can someone help? Thank you!
Valerie
