Features and Main Functions
Section 1-1
Note
For each input, a PLC Setup parameter determines whether it is to be used as
a normal input, interrupt input, quick-response input, or high-speed counter.
Analog Settings
Changing Settings Using
Analog Adjustment
By adjusting the analog adjuster with a Phillips screwdriver, the value in the
Auxiliary Area can be changed to any value between 0 and 255. This makes it
easy to change set values such as timers and counters without Programming
Devices.
Changing Settings Using
External Analog Setting
Inputs
External analog values of 0 to 10 V (resolution: 256) are converted to digital
values and stored in a word in the AR Area. This enables applications that
require on-site adjustment of settings that do not demand a particularly high
degree of accuracy, such as for example, a setting based on changes in out-
door temperatures or potentiometer inputs.
Phillips screwdriver
Analog adjuster
Ladder program
Example: The production quantity could be changed by
changing the counter set value from 100 to 150.
Turning the control on the CP1H changes the
PV in A642 between 0000 and 0255 (00 and
FF hex).
CNTX
A642
External analog setting
input connector
Ladder program
Example: The production quantity could be changed by changing
the timer set value from 100 to 150.
When a voltage (0 to 10 V) is input from a
device such as a potentiometer to the
external analog setting input, the PV in A643
is refreshed between 0000 and 0100 hex (0
to 256).
