How to understand COUNT UP in DCS program?
Thread Content
In the SEQUENCE FLOW CHART program of DCS, a washing counter (CT01=1 COUNT) appears during the discharging and washing process of the polymerization kettle, and in the following program, CT01=NOT COUNT UP. When CT01=NOT COUNT UP is N and Y, two situations occur in the program. I don’t understand what COUNT or COUNT UP means! ! ? I hope the experts can give me some guidance! !
Take a look at the variable table. This is a variable, not a function.
Know it is a variable! I just don’t know how to understand this variable! For example, in the subroutine of discharging materials from the polymerization kettle mentioned above, CT01 is the added value of the washing counter, which is CT01=1 COUNT, and the data in the data table of CT01 is 2 or 3. This data does not have a unit and is determined according to the formula! I don't understand what the attached value of 1 COUNT means! At the end of this subroutine, you need to check the cavitation of the pump. CT02 is the added value of CAVITATION COUNTER. It is CT02=1 COUNT and is set to SP=10TIMES. Immediately after, there is CT02=COUNT UP. Can you explain what it means! ?
