I am a new user to OPTO22, and I am having trouble programming. I can set up the flowchart. At this point I am having trouble making a counter work. I am using a digital input as a counter. I first clear the counter, then start the counter, and after a period of time I stop the counter and look at the counts, but I am not getting any counts. I watch the counter and see the XVAL is counting but the IVAL is not, what am I doing wrong?
