EJ30xx - Object description and parameterization

EtherCAT XML Device Description

The display matches that of the CoE objects from the EtherCAT XML Device Description. We recommend downloading the latest XML file from the download area of the Beckhoff website and installing it according to installation instructions.

Parameterization via the CoE list (CAN over EtherCAT)

The EtherCAT device is parameterized via the CoE - Online tab (with a double click on the respective object) or via the Process Data tab (assignment of PDOs). A detailed description can be found in the EtherCAT System-Documentation in chapter “EtherCAT subscriber configuration”
Please note the general CoE notes in the EtherCAT System Documentation in chapter “CoE-interface” when using/manipulating the CoE parameters:
- Keep a startup list if components have to be replaced
- Differentiation between online/offline dictionary, existence of current XML description
- use "CoE reload" for resetting changes

Introduction

The CoE overview contains objects for different intended applications:

Objects required for parameterization during commissioning:

Restore object index 0x1011
Configuration data index 0x80n0

Objects intended for regular operation, e.g. through ADS access.
Profile-specific objects:

Configuration data (vendor-specific) index 0x80nF
Input data index 0x60n0
Information and diagnostic data
ADC Value (Index 0x80nE),
Modular device profile (Index 0xF000),
Code word (Index 0xF008),
Module list (Index 0xF010)

Standard objects (Index 0x1000-0xFFFF)

The following section first describes the objects required for normal operation, followed by a complete overview of missing objects.
