am trying really hard to find information on how to control a relay. I am quite new to the development of LabView programs and have sort of an issue. I have a system that requires the control of solenoid valves. i have three relay outputs to drive solenoids to select one of the three pressure levels.Is there anyone out there who could give me some hints on where to start? i have fpga and real time module.i am using crio ,ni 9477,9425 modules.
