Several questions regarding the CS3000 function block
Thread Content
Recently, while reading the manual for the CS3000 function block, I encountered several common parameters that I don’t understand. I’d like to ask everyone for help. As shown in Figures 1 and 2 below, what are the functions of switches such as CSW, RSW, and BSW within this function block? Where is the operation marker OPMK used again? I see that many functions already have these parameters. Also, I know that RLV1/2 are used to prevent integral saturation, but I don’t understand how they work Under what circumstances are the SW33 and SW91 function blocks used in Figure 3? Her image is everywhere in the instructions too! Thank you~!
Why does it keep showing “server (IO) error” when uploading pictures? !
The SW module is a selector switch module; for specific values of 33 and 91, please refer to the Yokogawa CS3000 operation manual.
OPMK should be a marker; to give an example from our actual use: when opening a control group (CG) panel at the operation station, it is possible to choose to use OPMk on that panel. We have defined values such as “Under maintenance” and “MV limit”
Thank you to friend sunny upstairs for their helpful answer!
