KEEP B
KEEP(011) is used to maintain the status of the designated bit based on two
execution conditions. These execution conditions are labeled S and R. S is the
set input; R, the reset input. KEEP(011) operates like a latching relay that is set
by S and reset by R.
When S turns ON, the designated bit will go ON and stay ON until reset, regard-
less of whether S stays ON or goes OFF. When R turns ON, the designated bit
will go OFF and stay OFF until reset, regardless of whether R stays ON or goes
OFF. The relationship between execution conditions and KEEP(011) bit status is
shown below.
