ENWA Posted September 25, 2013 Report Share Posted September 25, 2013 Dear All, I want to setup the "High speed Counter Input" for frequency measurement. (In my case input I2). And then I use the "Linear" FB to scale Freq. to Flow. I have been told that I do not need to use "Frequency Measurement based on HSC" FB, is that correct? Can some one pleas help me?

Michael_P Posted September 25, 2013 Report Share Posted September 25, 2013 HI Jonas, The freq measurement will give you the HZ of the pulses incoming to the PLC at a 1000msec sample rate. You do not have to use this input but if you are measuring frequency it performs the work for you, you can the just input the frequency directly into a linearization FB and scale it accordingly. If you were to use the count you will need to generate your own method or calculation for the frequency measurement. You should end up with the same HZ value as the value stored into MI600 automatically. Mike Quote Link to comment Share on other sites More sharing options...
