About This Manual - Omron E3X-DRT21 Operation Manual

About this Manual:

This manual describes the installation and operation of the E3X-DRT21 (DeviceNet), E3X-SRT21
(CompoBus/S), and E3X-CIF11 (RS-422) Fiber Amplifier Sensor Communication Units. These Units
enable optical fiber communications for OMRON E3X-DA-N Digital Fiber Amplifiers and E39-TM1 Ter-
minal Block Units.
Please read this manual carefully and be sure you understand the information provided before
attempting to install or operate a Fiber Amplifier Sensor Communication Unit. Be sure to read the pre-
cautions provided in the following section.
Precautions provides general precautions for using a Fiber Amplifier Sensor Communication Unit and
related devices.
Section 1 provides an overview of the Fiber Amplifier Sensor Communication Units for DeviceNet,
CompoBus/S, and RS-422 communications, including their features, system configurations, specifica-
tions, and connection methods. This section also covers the differences between different models.
Section 2 provides details on the Fiber Amplifier Sensor Communication Unit for DeviceNet communi-
cations, including procedures and application examples for remote I/O communications and explicit
messages used by the Unit, part names and functions, operation procedures, wiring, and applications
available from the DeviceNet Configurator.
Section 3 provides details on the Fiber Amplifier Sensor Communication Unit for CompoBus/S com-
munications, including procedures and application examples for CompoBus/S remote I/O communica-
tions used by the Unit, part names and functions, operation procedures, and wiring.
Section 4 provides details on the Fiber Amplifier Sensor Communication Unit for RS-422 communica-
tions, including information on the models, procedures, settings, and application examples of Compo-
Way/F message communications used by the Unit, part names and functions, operation procedures,
and wiring.
Section 5 describes the procedure used to mount the Fiber Amplifier Sensor Communication Unit to
DIN Track and provides the dimensions of the Units.
Section 6 provides information for each Communication Unit on the types of errors that may occur,
including details on the indicator status, probable causes, and remedies.
The Appendices provide information on communications timing, monitoring incident light levels of
E3X-DA6-P Sensors, DeviceNet connection settings, and the device protocol for DeviceNet.
