The cursor in the lower left corner of the display indicates that the force set/

reset is in progress. Bit status will remain ON or OFF only as long as the key

is held down; the original status will return one cycle after the key is re-

leased.

3. Press the SHIFT+SET or SHIFT+RESET Keys to maintain the status of the

bit after the key is released. In this case, the force-set status is indicated by

an “S” and the force-reset status is indicated by an “R.”

To return the bit to its original status, press the NOT Key or perform the Clear

Force Set/Reset operation. Refer to 4-2-26 Clear Force Set/Reset for de-

tails.

Forced status will also be cleared when the PC’s operating mode is changed

(unless SR 25211 is ON, in which case forced status will not be cleared

when changing from PROGRAM to MONITOR mode) or when operation

stops as the result of a fatal error or power interruption.
