This operation is used to change the decimal value of a word being monitored
as unsigned decimal data, within a range of 0 to 65,535. A change into hexa-
decimal data is made automatically.
Words SR 253 to SR 255 cannot be changed.

cause equipment to operate unexpectedly or dangerously. In particular, take
care when changing the status of output bits. The PLC continues to refresh I/
O bits even if the PLC is in PROGRAM mode, so devices connected to output
points on the CPU Board or Expansion I/O Boards may operate unexpectedly.
1. Monitor (unsigned decimal) the status of the word for which the present
value is to be changed.
(Unsigned decimal monitor)
2. Press the CHG Key to begin decimal data modification.
3. Input the new PV and press the WRITE Key to change the PV. The opera-
tion will end and the decimal-without-sign monitoring display will return
when the WRITE Key is pressed.
The PV can be set within a range of 0 to 65,535.

useful when debugging the program or checking output wiring. It is possible in
MONITOR or PROGRAM mode only.

1. Monitor the status of the desired bit according to the procedure described
in 7-2-14 Bit, Digit, Word Monitor. If two or more words are being moni-
tored, the desired bit should be leftmost on the display.
