Controlling Interlock Status from the CX-Programmer
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 the CX-Programmer. The forced status of the Interlock Sta-
tus Bit has priority and overrides the interlock status calculated by program
execution.
Force-set: Releases the interlock.
Force-reset: Engages the interlock.
Note Program operation can be switched more efficiently by using interlocks with
MILH(517) or MILR(518).
