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.
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 index 0x80nE, 0xF000, 0xF008, 0xF010
• Standard objects
The following section first describes the objects required for normal operation, followed by a complete
overview of missing objects.
The parameterization of the terminal can be set in the CoE (CAN over EtherCAT) folder.
Parameterization via the CoE list (CAN over EtherCAT)
The terminal is parameterized via the CoE - Online tab [} 105] (double-click on the respective
object) or via the Process Data tab [} 102](allocation of PDOs). Please note the following general
CoE information when using/manipulating the CoE parameters:
- Keep a startup list if components have to be replaced
- Differentiate between online/offline dictionary, ensure existence of current XML description
- use "CoE reload [} 184]" for resetting changes
The following CoE settings are possible from object 0x8000 [} 155] and are shown below in their default
settings:
