7.6 Object description and parameterization
EtherCAT XML Device Description
The display matches that of the CoE objects from the EtherCAT XML Device Description. We rec-
ommend downloading the latest XML file from the download area of the Beckhoff website and in-
stalling it according to installation instructions.
Parameterization via the CoE list (CAN over EtherCAT)
The EtherCAT device is parameterized via the CoE-Online tab [ } 92] (double-click on the respective
object) or via the Process Data tab [ } 89] (allocation of PDOs). Please note the following general CoE
notes [ } 26] 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 (Index 0x6000-0xFFFF)
◦ Configuration data (vendor-specific) index 0x80nF
◦ Input data index 0x60n0
◦ Information and diagnostic data index 0x80nE, 0xF000, 0xF008, 0xF010
• Standard objects (Index 0x1000-0x1FFF)
The following section first describes the objects required for normal operation, followed by a complete
overview of missing objects.
