JOGGING output

[Danfossegypt]

hello everyone

i am working at a power station , and we have some jogging motorized valves(i.e motor is running as the command is available)
our DCS package is FOXBORO backage, my question is how can i have this type of output and how this application is implementeed in other systems, our engineers say that they cannot do it so they will send a 5 sec pulse for every mouse click)

if anyone have an idea so you are kindly requested to tell me

This is difficult to do with the DCS system I am working with. I just did a search of "JOG" in the help files for ours and it returned nothing. I don't know about Foxboro's package.

You might have to do a start/stop button on the package. The operator would have to start and stop it manually if the time that the valve opens is not too short.

They could also have the operator enter the length of time (in a parameter) they want the valve to move, and then hit a "Jog" button. Then your engineers could program the output to last the same amount of time that was entered.
