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

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.

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

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
