Help: Specific usage of the PTC block in Yokogawa CS3000
Pulse counter function block, which is intended to be used in conjunction with the AAP135 pulse count input module. When the number of pulses arriving at the site reaches the PH set value, a CTUP flag is output. For example, if a catalyst is added to a reaction vessel and the flow rate is measured using the pulse signals from a vortex flow meter, then once the cumulative flow rate corresponding to those pulses reaches a certain value, CTUP is used to control the valve to close.
