3. Press the CLR Key or the SHIFT and TR Keys to end the unsigned decimal
display and return to normal monitoring.
This operation is used to change the contents of one or more of the 3 con-
secutive words displayed in the Three-word Monitor operation. It is possible
in MONITOR or PROGRAM mode only.
RUN
No
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 the status of the desired words according to the procedure
described 4-3-16 Three-word Monitor.
(Three-word monitor)
2. Press the CHG Key to begin 3-word data modification. The cursor will
appear next to the contents of the leftmost word.
3. Input the new value for the leftmost word on the display and press the CHG
Key if more changes will be made.
(Input the new value and press the WRITE Key to write the changes in
memory if no more changes will be made.)
4. Input the new value for the middle word on the display and press the CHG
Key if the rightmost word will be changed. Input the new value and press the
WRITE Key to write the changes in memory if the rightmost word will not be
changed. (In this case, it will not.)

Note If the CLR Key is pressed before the WRITE Key, the operation will be cancelled
and the 3-word monitor display will return without any changes in data memory.
There are two operations that can be used to change the SV of a timer or
counter. They are possible in MONITOR or PROGRAM mode only. In MON-
ITOR mode, the SV can be changed while the program is being executed.
RUN
No
The timer or counter SV can be changed either by inputting a new value or
by incrementing or decrementing the current SV.
