[foxboro] Supervisory control

All,

I have a question on the Supervisory Control. I'm using Foxboro v7.1.1 &
wants to implement advanced controls which will require an external
controller to write to the existing PIDE controllers.  I know you can
set the SUPOPT = 1 and this enables writing SPT from external (in this
case, via OPC), but I heard this way is fraught with problems.

Can someone confirm this?
 
Best regards,
