[foxboro] Red background of PIDA block .MEAS

List,
 

Does anyone know what status bit is set in a PIDA block when the AIN
that is connected to the .MEAS goes bad that makes the .MEAS background
turn red?  We want that to not only turn red, but to display a line of
dashes, similar to what Honeywell points do when they go bad.  We
figured we could just put a red rectangle with dashes in it that has its
visibility set to whatever status bit is causing the red background, but
I've been looking through the block descriptions, and I can't locate it.
Our new graphic works great for AIN blocks, because AIN's have a BAD bit
in their .BLKSTA (and a .BAD parameter), but PIDA's do not, at least not
one that changes when you flip the incoming .MEAS from good to bad.

 

Thanks,
