8-2-25 Unsigned Decimal Data Modification
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.
!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 CPU Unit, Expansion Units, or Expansion I/O Units may operate
unexpectedly.

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.
If an erroneous input has been made, press the CLR Key to restore the sta-
tus prior to the input. Then enter the correct input.
The buzzer will sound if a value outside the specified range is input, allow-
ing no writing.

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.
