The contents of the specified word are converted automatically to signed hexadecimal (two’s complement format).119SectionProgramming Console Operations4-4Words SR 253 to SR 255 cannot be changed.RUNMONITORNoPROGRAMOKOK! CautionBefore changing the contents of I/O memory, be sure that the changes will notcause equipment to operate unexpectedly or dangerously.
In particular, takecare when changing the status of output bits. The PC continues to refresh I/Obits even if the PC is in PROGRAM mode, so devices connected to output pointson the CPU Unit, Expansion Units, or Expansion I/O Units may operate unexpectedly.1, 2, 3...1.

Monitor the status of the desired bit according to the procedure described in4-4-12 Bit, Digit, Word Monitor. If two or more words are being monitored,the desired bit should be leftmost on the display.0000020000^ OFF^ON(Multiple address monitor)2. Press the SET Key to force the bit ON or press the RESET Key to force thebit OFF.SET0000020000ON^ONThe 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 keyis held down; the original status will return one cycle after the key is released.3. Press the SHIFT and SET Keys or SHIFT and RESET Keys to maintain thestatus of the bit after the key is released. In this case, the force-set status isindicated 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 ClearForce Set/Reset operation. Refer to 4-4-25 Clear Force Set/Reset for details.Forced status will also be cleared in the following cases:a) When the PC’s operating mode is changed (although the forced statuswill not be cleared when the mode is changed from PROGRAM to MONITOR if SR 25211 is ON)b) When the PC stops because a fatal error occurred121SectionProgramming Console Operations4-4c) When the PC stops because of a power interruptiond) When the Clear Force Set/Reset Operation is performed4-4-25 Clear Force Set/ResetThis operation is used to restore the status of all bits which have been forceset or reset.
