jason Posted July 20, 2011 Report Share Posted July 20, 2011 I've implemented some hydraulic press controls using an M91 and a linear potentiometer. It works well, but there is room for improvement. On our next machine, I'm considering the vision series PLC but can't find a spec for m90 or vision that talks about sample rate of analog inputs. Can anyone point me to these specs? Thanks Quote Link to comment Share on other sites More sharing options...
MVP 2014 Simon Posted July 20, 2011 MVP 2014 Report Share Posted July 20, 2011 Hello Jason, Go to the Tech Library section of the Unitronics website http://www.unitronic...chnical_Library there are specification documents for each model, and usually in the section on analogue inputs there will be a conversion time. The final sample rate is a function of the conversion time and PLC scan time. If the conversion time is longer than the PLC scan, then it will determine the sample rate. Otherwise the PLC scan time will determine the sample rate. Quote Link to comment Share on other sites More sharing options...
