6-4-1
Analog Adjuster
By turning the analog adjuster on the CP1L CPU Unit with a Phillips screw-
driver, the PV in the Auxiliary Area (A642) can be changed to any value within
a range of 0 to 255.
Application Example
Setting the value for timer T100 in A642 makes it possible to use T100 as a
variable timer with a range of 0 to 25.5 s (0 to 255). A change in the set value
is reflected with the next scan.
Note
Set values from the analog adjuster may vary with changes in the ambient
temperature and the power supply voltage. Do not use it for applications that
require highly precise set values.
6-4-2
External Analog Setting Input
When a voltage of 0 to 10 V is applied to the CP1L CPU Unit's external analog
setting input terminal, the voltage is converted from analog to digital and the
PV in A643 can be changed to any value within a range of 0 to 256 (0000 to
0100 hex).
External Analog Setting

Use the 1-m lead wire (included) for wiring to the external analog setting input
connector on the CP1L CPU Unit.
