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 operation
will end and the signed-decimal monitoring display will return when the
WRITE Key is pressed.
The PV can be set within a range of --32,768 and 32,767. Use the SET Key to
input a positive number, and use the RESET Key to input a negative number.

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.
This operation is used to change the decimal value of a word being moni-
tored as unsigned decimal data, within a range of 0 to 65,535. A change into
hexadecimal data is made automatically.
Words SR 253 to SR 255 cannot be changed.
RUN MONITOR
No OK
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 or Expansion I/O Units may operate unexpectedly.
1. Monitor (unsigned decimal) the status of the word for which the present
value is to be changed.

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 operation
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.
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.
