1-1 Features and System Configuration
1-1-1 Overview
The Fiber Amplifier Sensor Communication Units are Communication Units
for E3X-DA-N-series Digital Fiber Amplifi er 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 S ensor Communication Un its can be connected to Fiber
Amplifier Units with Connectors. Connecting a Fiber Am plifier Sensor Communication Unit to the l eft side of one or more Fiber Amplifi er Units allows
data to be exchanged with the Fiber A mplifier Sensor Units via optical communications.
Note When using a Fibe r Amplifier Sensor Communicatio n 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.

various teaching operations. (DeviceNet models u se explicit messages, and
RS-422 Communication Units use CompoWay/F commands.)
With DeviceNet models, the DeviceNet Configurator (Ver. 2. 10 or higher) ca n
be used to set Fiber A mplifi er Sens or Co mmunicat ion Uni t pa rame ters (C ommunication Unit settings and Sensor settings) and download them to the
Communication Unit and Fiber Amplifier Unit as a batch.
The E3X-MC11 Mobile C onsole for Fiber Ampl ifier Units ca n be co nnecte d to
the Communication Unit. Th e head for connecting to the Mobile Console is
not required when it is connected to a Communication Unit.

1-3-6 Regi stering the Number of Sensors
To detect wh ether communica tions with F iber Amplifi er Units are n ormal, th e
number of Fiber Amplifier Units connected must be registered. When the
number of Fiber Amplifier Units connected is registered, errors can be
detected when there is no optical communications response from Sensors
due to malfunctions in Fiber Amplifier Units. The errors can be detected by the
difference between the number of Fiber Am plifier Units communicating and
the number registered as connected.
A difference between the number of Fiber Amplifier Units connected and th e
number of registered Units is indicated as follows:
• The SS indicator lights red.
• The Sensor Communications Error Flag turns ON.
The following table shows the method used to set the number of Sensors connected to the Unit

2-1 Overview of DeviceNet Communications Model
2-1-1 Introduction
The E3X-DRT21 for DeviceNet communications is a Communication Unit that
uses the DeviceNet to communicat e with one or more Fi ber Optical Senso rs
through Fiber Amplifier Units, including monitoring ON/OFF output signals
and incident light levels, writing parameters, and controlling operation.
Remote I/O communications can be use d to monitor ON/OFF output signals
and incident light levels without special programming. Explicit m essages can
be used to read and write parameters and the DeviceNet Configurator
enables transferring and monitoring parameters as a batch.
Note When DeviceNet Communication Units are used, however, Fiber Amplifier
Units can output ON/OF F signals via communi cations only. (Fiber A mplifier
Units can be connecte d to Cordless Slave Connectors only. They cannot be
connected to Slave Connectors with Cords.)
Refer to the following manuals when using a DeviceNet Communication Unit:
DeviceNet Operation Manual (Cat. No. W267) and DeviceNet Slave Manual
(Cat. No. W347).

Note Fiber Amplifier Units (E3X-DA6TW and E3X-DA8TW) that are allocated two
unit numbers must be counted as two Units when counting the number of connected Sensors.
■ Pin 3: Controlling the Setting of the Number of Connected Sensors
The number of Sensors connected is registered by using either a rotary switch
or the Configurator.
When pin 3 is ON, r egi stering the number of Se ns ors i s ena bled from Configurator or by using explicit messages enabled, and the value for the number of
Sensors enabled for communications that is stored i n the inter nal memor y of
the Fiber Amplifie r Sensor Communic ation Unit is us ed. The default value in
the internal memor y is 16. This value can be changed from the DeviceNet
Configurator. The setting methods are shown in the following table.
Pin 3 Method for setting the number of Sensors
OFF Use rotary switch to register number of Sensors.
ON Use Configurator or e xp lic it mes sa ge s to regi ste r n um be r of Se ns ors.
Note When DIP switch pin 3 is ON (register ing from Configurator or using explicit
messages), pin 1 is OF F, a nd pin 2 is ON (remote I/O communi cations twoword mode with incident light level monitor ing) , the value in the i nternal memory of the F i ber A mp li fie r Se nso r Com mu nicati on Uni t for the number o f Un its
being monitored for incident light levels is used. The d efault value in the i nternal memory is 16. This value can be se t to a different value from t he number
of Sensors connected. When pin 3 is OFF (registering from rotary switch), pin
1 is OFF, and pin 2 is ON, the rotary switch setting applies to both the number
of Sensors connected and the number of Units monitoring incident light level.
■ Pin 4: Reserved for System Use
This pin must always be OFF.
Sensor Reset Switch Press this switch to reset the connected Sensors by executing power interrup-
tion processing. This switch is used in the following case.
If the number of Sensors with co mmunications enabled does not match the
number of Sensors connected , one or more Sensors may have become disconnected. The power res et switch is require d to enable the Sensors to be
reconnected properly and for communications to be reestablished between
Sensors. Tur ning OFF th e power supply would disc onnect the F iber Amplifi er
Sensor Communication Un it f ro m D eviceNet, whic h may effect the enti re s y stem. The Sensor reset switch is thus used to reestablish communications with
the Sensors.
Note The E3X-DRT21 automaticall y uses the DeviceNet baud rate of the master.
Therefore, the DIP switch is not required to set the baud rate.

level data for the Sensors not communicating will be 7FFF.
4. The incident light level data for the E39-TM1 Te rmin al Block Units will be
7FFF. Monitoring incident light levels for Terminal Block Units causes a delay in the data refresh cycle. To speed up the refresh cycle, mount the Terminal Block Unit to the farthe st position from the Fiber Amplif ier Sensor
Communication Unit, and use th e Devi ceNet Configurator or an explicit
message to set the number of devices to be monitored for incident light level requirement so that the Terminal Block Unit is not monitored.
5. The refresh timing of Sen sor ON/OF F data and i ncide nt light level data is
not synchronized. Even if incident light level data is read whi le monitoring
the ON/OFF status, the incident light level data may not be indicated for the
ON and OFF status. To re ad inciden t light level data at ON and OFF, use
the E3X-DA6-P Sensor. For details on this Sensor, refer to Appendix B

Note 1. The un it number specified by the in stance ID must be set bet ween 0001
Hex and 0010 Hex.
2. An error will occur if the unit number of an E39-TM1 Terminal Block Unit is
specified.
3. When WRITE commands a re executed, the settings are w ritten to the internal memory . The number of times that data can be written to the internal
memory is limited. The internal memory may be corrupted if more than one
million (1,000,000) write operations are performed for each Sensor and parameter. Therefore, when using WRITE comman ds, be sure to create a
communications program th at prevents the number of writing operations
from exceeding one million (1,000,000) for each Sensor and parameter.
4. Do not send commands for attribute ID that are not specified. Accidentally
sending such commands may overwrite internal parameters. If the internal
parameters of a con nected Sensor are overwrit ten, execute the Initialize
Sensor Settings ope ration command . If the inter na l parameters of the Fiber Amplifier Sensor Communication Unit are overwritten, write 0000 Hex
for the following attribute ID settings to clear them.

Note 1. The Write Threshold Setting command cannot be executed when the Zero
Reset setting is enabled. Disable Zero Reset to execute the Write Threshold Setting command.
2. The setting range of Write Threshold Setting command changes when the
Write Hysteresis Width command is executed. An error will occur if the value written is outside the setting range.

3-1-1 Introduction
The E3X-SRT21 for CompoBus/S communicatio ns is a Communication Unit
that uses the CompoB us/S to monitor the ON/ OFF output signals of o ne or
more Fibe r Optical Sen sors through Fiber Amplif ier Units. Remot e I/O communications can be us ed to moni tor ON/OFF output signal s without any special programming.
Note When using CompoBus/S Communication Units, do not read ON/OFF signals
via the Fiber Amplifie r Unit cable. (Fiber Amplifi er Units can be con nected to
Cordless Slave Connectors only. They cannot be connected to Slave Connectors with Cords.)

F message used is the Wri te to Parameter Area comm and for Write Num ber
of Sensors Connected (MRC = “02”, SRC = “02”, parameter type 4005).
When pin 3 is ON (registration u sing CompoWay/F messages), the value for
the number of Sensors able to communicate that is stored in the internal
memory of the Fiber Amplifier Sensor Communication Unit is enabled. The
default value in the internal memory is 16 Sensors. This value can be
changed using CompoWay/F message communications. The setting methods
are shown in the following table.
Pin 3 Method for setting number of Sensors

Sensor Reset Switch Press this switch to reset the connected Sensors by executing power interrup-
tion processing. This switch is used in the following case.
If the number of Sensors with co mmunications enabled does not match the
number of Sensors connected , one or more Sensors may have become disconnected. The power res et switch is require d to enable the Sensors to be
reconnected properly and for communications to be reestablished between
Sensors. Tur ning OF F the power supply would result in no response to CompoWay/F, which may effect the entire system. The Sens or reset switch is thus
used to reestablish communications with the Sensors.

Number of Elements
Specifies as hexadecimal AS CII the number of Units star ting from the sp ecified unit number that are to be read fr om. The leftmost bit is set to 1. Therefore, the number of elements is set to “8001” to read one Unit. Unless
executing Read Threshold Setting, the number of elements can be set to
“8001” only .
Read Data
Gives the data read in hexadecimal ASCII.
The following information describes the data format for each item.
Read Number of Sensors
Connected
15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00
Number of Sensors connected
Reads as a 4-digit hexadecimal value the number of Sensors connected.
When DIP switch pin 3 is ON, the value is read from the internal memory, and
when pin 3 is OFF, it is read from the rotar y switch setting. The data range is
0001 Hex to 0010 Hex (1 to 16 Units).
Read Response Delay
Time
Reads as a 4-digit hexadecimal value the Communication Unit’s response
delay time (time for a CompoWay/F response to be retur n ed). T he un it is ms.
Some CompoWay/F masters, such as CQM1H Serial Communications
Boards, cannot read responses that are return ed too quickly. For such masters, the Communication Un it response delay time can be set by using th e
Write Response Delay Time command. The default setting is 0 ms.
Read Threshold Setting Reads as a b atch the thr eshold settings for the number of S ensors speci fied
in the number of elements after the unit number specified in read start
address. The data is g iven as a 2-byte (4-digit) hexadecimal value for each
Unit, and negative data is expressed as its two’s complement.

Note 1. When W RITE com mands are executed, the settings are wr itten to the in-
ternal memory . The number of times that data can be written to the internal
memory is limited. The internal memory may be corrupted if more than one
million (1,000,000) write operations are performed for each Sensor and parameter. Therefore, when using the Write to Parameter Area, be sure to
create a communications program that prevents the number of writing operations from exceeding one million (1 ,000,000) for each S ensor and parameter
