4 Configuring System

4.1 Obtaining Device Files

The device files for EDATEC EtherCAT coupler and EtherCAT I/O modules are integrated. Both the EtherCAT coupler and EtherCAT I/O modules use the same device file, which can be downloaded at: ED-EIOBRG-EC Device Fileopen in new window.

  • In an actual network configuration where both the EtherCAT coupler and EtherCAT I/O modules are used, you only need to install the device file once when connecting the EtherCAT coupler.
  • If the EtherCAT I/O modules are used independently in the network, the device file must be installed separately.

4.2 Configuration Example

An example of building an EtherCAT coupler configuration environment with CODESYS Soft PLC as the master.

Preparation:

  • A PC with CODESYS V3.5.19.0 or later installed.
  • A number of network cables have been acquired.
  • The available EtherCAT couplers (ED-EIOBRG-EC) have been acquired.
  • The device description file (e.g. “ED-EIOBRG-EC-xxxxxx.xml”) for the EtherCAT coupler ED-EIOBRG-EC has been obtained.
  • The connection of the EtherCAT analog module to the EtherCAT coupler has been completed.

Steps:

  1. Double-click the CODESYS icon on the PC desktop to open the CODESYS software. Select “Tools” → “Device Repository” in the menu bar.
