[foxboro] Control of Switchgear

Hello everyone.
 

We currently have an issue on site with the control of our HV breakers.

 

The existing configuration uses a GDEV and CALC block combination for
operating the switches, but this has limitations. In particular, we need the
breakers to be controlled from...

 

a)                   a sequence

b)                   an Operator (from the Control Room when the breaker is
selected to "Remote")

c)                   an Operator (from the switch itself when it is selected
to "Local")

 

Just now the GDEV is held in manual, which results in a State Alarm every
time we switch locally - not ideal.

 

My main question is how do you guys control switchgear? How do you manage to
switch from any of the 3 locations mentioned above?
