Moran Posted August 28, 2012 Report Share Posted August 28, 2012 Hello, I am new in plc and visilogic and i need some help, I need to measure the frequency of a square wave , I tried to use HSC Frequency Measurement FB , but it does not work. ( my square wave freq is slow... about 2Hz) I connected my signal to I0 of a V200. Can someone please tell me what should I do to measure the freq of that signal? Do you have any example? I am using V570 and V200-18-E2b By the way: My square wave should be 24v? Thanks, Moran. Quote Link to comment Share on other sites More sharing options...
