SYSMAC CP1L Getting Started Guide
Analog values can be digitized according to the external analog settings input (0 to
10V, resolution: 256). Converted values are sent to the auxiliary area (A643CH).
This function is useful for changing settings based on inputs such as change in
outside temperature or feedback from a variable resistor.
An example using input from a variable resistor is shown below.
A photoelectric sensor is placed in front of a gate. When the sensor detects a car,
the gate is opened.
When the car passes the gate, the sensor is turned OFF.

When a set amount of time passes after the sensor is turned OFF, the gate is closed.

The time until the gate closure will be adjusted with by a variable resistor connected
to CP1L.
