Features and System Configuration
Overview
The Communication Unit (E3X-DRT21-S) is a communication slave that performs the ON/
OFF output for sensors, monitoring the detection level, writing parameters, and an
operation between Digital Type Sensors and PLCs via DeviceNet communication.
(Supported sensors are: Fiber Sensors E3X-DA-S/MDA series, Separate Amplifier Laser
Sensors E3X-LDA series, and Separate Amplifier Proximity Sensor E2C-EDA series.)
The ON/OFF output and monitoring the detection level can be performed using remote I/O
communications without any programming. Moreover, reading and writing any parameters
using Explicit messages, and batch-transfer and monitoring any parameters using a
configurator are possible.
If the Sensor is connected using a connector with a cable, external noise may prevent correct
communication of ON/OFF signals to the Communication Unit. If a high level of reliability is required,
use a cordless connector (E3X-CN02).
