ROUT
ROUT
(OP)
Is it very common to use the ROUT of a controller?
I just ran across this in a plant. The engineer said he could not tune the controller (in a DCS) to behave how it needed, so he developed three different equations to determine valve position and sends it to the ROUT of the controller.
My concern is that once this engineer leaves, nobody will understand where these equations came from or why a controller is in ROUT (since it doesn't seem that common).
The plant does not have a process controls departmemt or group or anything to support the DCS.

RE: ROUT
What kind of loop is he trying to tune and what DCS are you using?
I wouldnt let him go to far without a detailed explanation.
Just post a little more info. My search is not coming up with much.
Thanks
Good Luck!
