Re: [foxboro] Resetting graphics optimization for FoxView?

I have worked at sites with generic overlays & custom (individual)
overlays.
I believe the benefits of using custom overlays exceeds the info you can
present using generic overlays.
The custom overlays are bulk generated (or created as needed using
d_edit scripts/templates) but are then individually modified as
necessary to show detailed info that is unique to the mtr/loop.
Examples of customised info - motor auto start/stop logic, start only
permits, interlocks. If a mtr auto starts on low pressure then the mtr
overlay would have a live connection to the block low alarm limit to
show the actual value.
Custom overlays do require a bit more effort but the Operators are more
informed & it helps Maint staff.
Fox View needs an improved display optimisation process.

Is there a reason why you are not using generic overlays with either
the "ov_conn" command or substitution scripts?
=20
This would require reconfiguring the primary graphics but would
eliminate all but one generic and few non-standard overlays per overlay
type (i.e motor, control.etc.).  Does not solve the problem of
optimizing the displays, however it will reduce the overall number of
graphics.

On two of our three sites we have implemented the "ov_conn" command to
call generic overlays. On the third site we use scripts which will be
replaced with the "ov_conn" command when we move from Display Manager to
FoxView.

Welcome to our paper machine! <grin>

I just checked one of the FoxView workstations and it has 4818 .fdf
files under
the operator graphic directory.  The breakdown is something like this:
~400 primary graphics
~1000 motor overlays
~1800 control overlays
~600 hand controls overlays
~300 misc overlays
~700 graphics and overlays that are obsolete, redundant, work in
progress,
backup or have no readily obvious purpose to me.

I could get this information through OAJ.  Many of the graphics are not
needed
or used on a day-to-day basis, however that doesn't make them any less
important
when they need to be used. =20

Unfortunately not practical.  When an operator needs to take rapid
action, the
30 second delay only to call up a smurfed out graphic is unacceptable.
