I’m trying to read a magnetic pickup (flow meter) with an IDC5-FAST-A module. The flow meter has 2 test modes that output 10Hz and 250Hz. With both I can see in the software that the inputs are turning on and off, and I do have the input configured for frequency, but GetFrequency() always returns 0. When I view the module in debug, the textbox also shows the frequency as 0, but I can watch the state go on/off. Does anybody know what might be going on?
