System Configuration

4-2 System configuration examples

This section outlines the system configurations for measurement using an external trigger, such as mea-
surement using a photo sensor, measurement using CCD trigger, and measurement triggered by a com-
mand from a personal computer.
See Chapter 11 "Setting the Input/Output Conditions" for the details about the settings.
[1] System configuration example for measurement triggered by an external trigger, such as a
photo sensor
(1) When IV-S20 is used in a stand-alone mode
- Purpose/application
Measurement is started by an external trigger (a photo sensor or proximity sensor), and the
measurement result is output externally (warning lamp). The object type number is selected by
an external switch.

(2) When a programmable controller is connected
- Purpose/application
Measurement is started by an external trigger (a photo sensor or proximity sensor), and the
measurement data is output to a programmable controller. The object type number is selected
by the programmable controller.
