The Fiber Amplifier Sensor Communication Units are Communication Units
for E3X-DA-N-series Digital Fiber Amplifier Units or E39-TM1 Terminal Block
Units. (See note.) The following three models are available.
• E3X-DRT21 for DeviceNet (functions as a DeviceNet slave)
• E3X-SRT21 for CompoBus/S (functions as a CompoBus/S slave)
• E3X-CIF11 for RS-422 (functions as a CompoWay/F slave)
Note In this manual, Digital Fiber Amplifier Units and Terminal Block Units are
referred to collectively as Fiber Amplifier Units.
The Fiber Amplifier Sensor Communication Units can be connected to Fiber
Amplifier Units with Connectors. Connecting a Fiber Amplifier Sensor Com-
munication Unit to the left side of one or more Fiber Amplifier Units allows
data to be exchanged with the Fiber Amplifier Sensor Units via optical com-
munications.
Note When using a Fiber Amplifier Sensor Communication Unit for DeviceNet or
CompoBus/S communications, however, a Slave Connector with Cord cannot
be connected to a Fiber Amplifier Unit with a Connector. Use a Cordless
Slave Connector instead.
The E3X-MC11 Mobile Console for Fiber Amplifier Units can also be con-
nected to a Fiber Amplifier Sensor Communication Unit.
The Fiber Amplifier Sensor Communication Unit enables communications
between optical sensors and a host, such as an OMRON PLC (CS-series, CJ-
series, C200HX/HG/HE, or other OMRON PLC), other manufacturer's PLCs
that support DeviceNet, and personal computers.
Information on the Fiber Amplifier Unit's ON/OFF output signals and incident
light levels can be sent to the host PLC (master) using remote I/O communi-
cations without any special programming (supported only for Fiber Amplifier
Units for DeviceNet and CompoBus/S communications).
Sending commands from the PLC allows reading parameters (such as those
for incident light levels), writing parameters (such as those for thresholds), and
various teaching operations. (DeviceNet models use explicit messages, and
RS-422 Communication Units use CompoWay/F commands.)
With DeviceNet models, the DeviceNet Configurator (Ver. 2.10 or higher) can
be used to set Fiber Amplifier Sensor Communication Unit parameters (Com-
munication Unit settings and Sensor settings) and download them to the
Communication Unit and Fiber Amplifier Unit as a batch.
The E3X-MC11 Mobile Console for Fiber Amplifier Units can be connected to
the Communication Unit. The head for connecting to the Mobile Console is
not required when it is connected to a Communication Unit.
Note The Mobile Console can be used in conjunction with monitoring ON/OFF out-
put signals through remote I/O communications. The Mobile Console cannot
be used, however, in conjunction with remote I/O communications for monitor-
ing incident light levels, message communications, and using the Configurator
for transferring device parameters.
