Status of C
KEEP(011) has an immediate refreshing variation (!KEEP(011)). When an
external output bit has been specified for B in a !KEEP(011) instruction, any
changes to B will be refreshed when !KEEP(011) is executed and reflected
immediately in the output bit for the CPU Unit built-in output.
KEEP(011) operates like the self-maintaining bit, but a self-maintaining bit
programmed with KEEP(011) requires one less instruction.

Self-maintaining bits programmed with KEEP(011) will maintain status even in
an interlock program section, unlike the self-maintaining bit programmed with-
out KEEP(011).
Output bit C will maintain its
previous status in an interlock.
100.00
Output bit C will be turned
OFF in an interlock.
