[foxboro] AW: Control Loops.

Hi,

that is one of greatest question in plant automation.=20
I searched at information but didn't find any specific.

You won't find friends in the event that you try to migrate knowledge
from other sources (scientific institutes, military, institutes who
research the human behavior by driving a car (in germany www.bast.de))
to you specific needs.

The scientists didn't like non-scientists and your plant leader isn't
interested limiting the operator work load. That's my experience.

Regards,
Andreas

Betreff: [foxboro] Control Loops.



Hello,

I am trying to find out if there is any standard as to how many control
loops a console operator can reasonably handle. I recall an old rule of
thumb that defined "equivalent control loops": 1 valve or 4 indications
=3D
or 8
contacts can be considered an "equivalent control loop" and an operator
=3D
was
supposed to be able to handle up to 250 of these. Any insight on the =
=3D
matter
will be very wellcomed.
Thank you.
