CoE object description 1:

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.

Notice

CoE object description 2:

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:

CoE object description 3:

CoE is generated depending on the module/slot assignment

The names and contents of the CoE directory are generated depending on the module/slot assignments.

  • In the following description of the CoE objects, some objects therefore have different names and contents, depending on the configuration of the modules, with the same index.
    Example:
    Module: …_DI => 0x80n0:0 “DI Settings”
    Module: …_ENC => 0x80n0:0 “ENC Settings 1”
  • The descriptions of the process data and settings objects are given below for each ModuleGroup.
  • The placeholder “n” describes the assignment of index labels corresponding to the respective configuration of the individual SlotGroups.
    Example:
    SlotGroup1 is assigned to ModuleGroup: PWM_OUT_REAL32_DI
    => 0x8000 “PWM Settings”, 0x8010 “DI Settings”
    SlotGroup2 is assigned to ModuleGroup: PWM_OUT_REAL32_DI
    => 0x8020 “PWM Settings”, 0x8030 “DI Settings”
