This operation can be used to increment and decrement an SV constant. It is
possible only when the SV has been entered as a constant.
1. Press the CLR Key to bring up the initial display.
2. Display the desired timer or counter.
TIM
3. Press the Down Arrow, CHG, and then the EXT Key.

The constant on the left is the old SV and the constant on the right will be-
come the new SV constant in step 5.
4. Press the Up and Down Arrow Keys to increment and decrement the con-
stant on the right. (In this case the SV is incremented once.)
5. Press the CLR Key twice to change the timer's SV to the new value.
CLR
This operation is used to change the BCD or hexadecimal value of a word
being monitored using the procedure described in 4-2-14 Bit, Digit, Word
Monitor. It is possible in MONITOR or PROGRAM mode only.
RUN
No OK
Words SR 253 to SR 255 cannot be changed.
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 unex-
pectedly.
1. Monitor the status of the desired word according to the procedure described
in 4-2-14 Bit, Digit, Word Monitor. If two or more words are being monitored,
the desired word should be leftmost on the display.
(Word monitor)
2. Press the CHG Key to begin hexadecimal, BCD data modification.
3. Input the new PV and press the WRITE Key to change the PV.
The operation will end and the normal monitoring display will return when
the WRITE Key is pressed.
