1. Introduction
The EC2-DIO series are industrial EtherCAT slave remote I/O modules supporting EtherCAT protocol
and installed by daisy chain connection which permits the flexibility in devices installation and
reduces infrastructure and operation costs. All the modules can be deployed in the network
topologies such as star, line or ring. The isolated input and output design protects the EC2-DIO
series against the harmful interference and environment.
The EC2-DIO series has passed and verified by the conformance test tool, therefore eligible
EtherCAT Master or configurator can manipulate it simply and implement your various applications
easily. Fig 1.1 is shown a typical EtherCAT application.

2. Hardware Information
2.1 Appearance
The front panel and top panel of the EC2-DIO series module contain the I/O connector, LEDs,
Ethernet Port and power connector.
1.
DC Power Input Connector
The “24V”and “GND” pins are used for the power supply applies to all types of EC2-DIO series
module. The valid power voltage range is from +10 to +30 VDC.
The definition of “F.G.”(Frame Ground):
Electronic circuits are constantly vulnerable to
Electrostatic Discharge (ESD), which becomes worse in a continental climate area. EC2-DIO series
module feature a new design for the frame ground, which provides a path that bypasses ESD,
resulting in an enhanced ESD protection capability and ensuring that the module is more reliable.
2.
EtherCAT Interface
EC2-DIO series modules are equipped with two RJ-45 EtherCAT Interface ports.
IN
is EtherCAT
signal input port that connect EtherCAT Master or EtherCAT signal output of previous EtherCAT
slave module，OUT
is EtherCAT signal output that connect the next EtherCAT signal input of
EtherCAT slave module.

3. Getting Started
This chapter provides a basic overview of how to configure and operate your EC2-DIO series
module.
3.1 Connecting the Power and the Host PC
Step 1
Connect both the IN port of EC2-DIO module and RJ-45 Ethernet port of Host PC.
Ensure that the network settings on the Host PC have been correctly configured and are functioning
normally. Ensure that the Windows firewall or any Anti-Virus firewall is properly configured to allow
incoming connections, or temporarily disable these functions.
Step 2
Apply power to the EC2-DIO module

Connect the Host device to the
IN Port on EC2-DIO module.

Connect the 24V pin to positive
terminal on a +10 ~ +30 VDC power
supply, and connect the GND pin to
the negative terminal.
NOTE: Attaching an ESC (EtherCAT Slave Controller) directly to an office network will result in
network flooding, since the ESC will reflect any frame – especially broadcast frames – back into
the network (broadcast storm).

3.2 Configuration and Operation
Beckhoff TwinCAT 2.X is most commonly used EtherCAT Master software to operate ECAT-2000
module.
Inserting into the EtherCAT network
NOTE
Installation of the latest XML device description(ESI)
Please ensure that you have installed the latest XML device description in TwinCAT.
This can be downloaded and unzip file from the ICP DAS website
(https://www.icpdas.com/tw/download/file.php?num=18279) and installed according
to the installation instructions.
Step 1
Automatic Scanning
The EtherCAT system must be in a safe, de-energized state before the module connected to
EtherCAT network!
Switch on the operating voltage, open the TwinCAT System Manager (Config mode), and scan
in the devices (below the picture). Acknowledge all dialogs with “OK”, so that the configuration
is in “FreeRun”mode.
