Controlling Interlock Status from a Programming Device
An interlock can be engaged or released manually by force-resetting or force-
setting the Interlock Status Bit (specified with operand D of MILH(517) and
MILR(518)) from a Programming Device. The forced status of the Interlock
Status Bit has priority and overrides the interlock status calculated by program
execution.
Force-set: Releases the interlock.
OFF

controlled by interlock
Force-reset: Engages the interlock.
ON
Program section
controlled by interlock
Note Program operation can be switched more efficiently by using interlocks with
MILH(517) or MILR(518).
Instead of switching processing with compound conditions, insert an
MILH(517) or MILR(518) instruction before each process and an MILC(519)
instruction after each process.
