7-3-24 Force Set, Reset
This operation is used to force bits ON (force set) or OFF (force reset) and is
useful when debugging the program or checking output wiring. It is possible in
MONITOR or PROGRAM mode only.
!Caution Before changing the contents of I/O memory, be sure that the changes will not
cause equipment to operate unexpectedly or dangerously. In particular, take
care when changing the status of output bits. The PC continues to refresh I/O
bits even if the PC is in PROGRAM mode, so devices connected to output
points on the Output Units may operate unexpectedly.
1,2,3... 1. Monitor the status of the desired bit according to the procedure described
in 7-3-12 Bit, Digit, Word Monitor. If two or more words are being moni-
tored, the desired bit should be leftmost on the display.
(Multiple address monitor)
2. Press the SET Key to force the bit ON or press the RESET Key to force the
bit OFF.
