Overview of Configuration Devices

The overview of each configuration device is as follows:
EtherCAT Master Unit
Administers the EtherCAT network, monitors the state of Slave Units, exchanges I/O data with Slave
Units.
EtherCAT Slave Unit
Outputs data received from the EtherCAT Master Unit through the EtherCAT network, or sends input
data to the EtherCAT Slave Unit through the EtherCAT network.
There are Digital I/O Slave Unit and Analog I/O Slave Unit.
Configuration Tool
It is a PC software for making setting of the EtherCAT network and each Slave Unit.
It can be used either by connecting to the EtherCAT Master Unit or as a substitute of the EtherCAT
Master Unit.
Communications cable
Uses cables of Ethernet category 5 (100BASE-TX) or higher, with double-shield (aluminum tape and
braided shielding), which are connected straight.
Refer to "4-2 Connecting to EtherCAT Network" on page 4-4.
ESI (EtherCAT Slave Information) file
Describes information specific to EtherCAT Sensor Communication Units in XML format.
You can load an ESI file into the Configuration Tool to easily allocate slave process data and make
other settings.
Refer to "5-2 EtherCAT Slave Information File (ESI File)" on page 5-3.
Unit power supply
Provides power for communications of each Slave Unit and internal operations.
Separate them from the I/O power supply when wiring.
Refer to "4-3 Connecting to Unit Power Supply and I/O Power Supply" on page 4-8.
I/O power supply
Provides power for input/output operations of external devices connected to Slave Units.
Separate from Unit power supply when wiring.
The E3NW-ECT does not require an I/O power supply.
