The status of displayed bits can be changed at this point. Refer to
3-3-19 Binary Data Modification for details.
b) The Up or Down Cursor Key can be pressed to display the status
of the previous or next word’s bits.
3. Press the CLR Key to end binary monitoring and return to the normal moni
toring display.
Press the SHIFT+CLR Keys to end monitoring altogether.
3-3-18 Hexadecimal, BCD Data Modification
This operation is used to change the BCD or hexadecimal value of a word
being monitored using the procedure described in 3-3-12 Bit, Digit, Word
Monitor. It is possible in MONITOR or PROGRAM mode only.
RUN MONITOR PROGRAM
No
OK
Words SR 253 to SR 255 cannot be changed.
1. 2. 3…
OK
1. Monitor the status of the desired word according to the procedure described
in 3-3-12 Bit, Digit, Word Monitor. If two or more words are being monitored,
the desired word should be leftmost on the display.
2. Press the CHG Key to begin hexadecimal, BCD data modification.

If a timer or counter is leftmost on the display, its PV will be displayed and will
be the value changed.
In MONITOR mode, the timer’s PV will be counting down if the timer is on.
3. Input the new PV and press the WRITE Key to change the PV. Be sure to
input timer or counter PVs in BCD only.
The operation will end and the normal monitoring display will return when
the WRITE Key is pressed.

The timer’s PV will continue counting down from the new PV if the timer is
on.
3-3-19 Binary Data Modification
This operation is used to change the status of a word’s bits when the word is
monitored using the procedure described in 3-3-17 Binary Monitor. It is pos
sible in MONITOR or PROGRAM mode only.
RUN MONITOR PROGRAM

Bits SR 25300 to SR 25507 cannot be changed.
1. 2. 3…
OK
1. Monitor the status of the desired word according to the procedure described
3-3-17 Binary Monitor.
2. Press the CHG Key to begin binary data modification.
A flashing cursor will appear over bit 15. The cursor indicates which bit can
be changed.
3. Three sets of keys are used to move the cursor and change bit status:
a) Use the Up and Down Cursor Keys to move the cursor to the left and
right
Use the 1 and 0 keys to change a bit’s status to on or off. The cursor will
move one bit to the right after one of these keys is pressed.
c) Use the SHIFT+SET and SHIFT+RESET Keys to force-set or force-re
set a bit’s status. The cursor will move one bit to the right after one of
these keys is pressed. The NOT Key will clear force-set or force-reset
status.
