Will flip the state of a tag. Intended for use with digital tags, but will work with analog tags. Used with SETVAL. If digital state is 0 and is a two state digital, %REVERSE will flip state from 0 to 1. If analog tag, %REVERSE will flip it based on percent of span. If current value is 25% of span, %REVERSE will make it 75% of SPAN.
Examples:
# Tcl - will reverse the state of PumpStart
# from On to OFF or from OFF to on
SETVAL PumpStart=%REVERSE
// JScript
SETVAL("PumpStart=%REVERSE");
Rem VB Script
SETVAL "PumpStart=%REVERSE"
