Re: [foxboro] AIN Block Invert


I would set KSCALE -1.0 and BSCALE 100.  I have used the settings before
for an inverse level indication.

I have an AIN point that is inversely proportional to a level.  Does anyone
know if I can invert the reading to the .PNT within the block, maybe using
KSCALE and BSCALE?  I thought BSCALE of -100 and KSCALE of -1.0 should work
but I just get BAD I/O readings when I do it.  I want the scale to be 0 -
100%.  When I get 4 mA, I want to show 100% and when I get 20 mA I want to
show 0%.  Thanks for any help.
