Operation/Description
Key sequence
Modes*
SV Change, 
SV Reset
There are three ways of modifying
the SVs for timers and counters.
One method is to enter a new value.
The second is to increment or
decrement the existing SV. In
MONITOR mode the SV can be
changed while the program is being
executed. Incrementing and
decrementing can only be carried
out if the SV has been entered as a
constant.
The third method is to change the
value properties from that of a
constant to a word address, or vice
versa. Note that the display clears
after pressing the CHG key and the
subsequent keystrokes determine
whether the new data will be
entered as a word address
(pressing SHIFT CH/* plus Word
address) or a constant (entering
data only).
