EDS/XDD Settings

CAN line-specific EDS/XDD settings are only used for the device descriptions in the EDS and XDD file. These settings do not enable the corresponding functionality in the device.

Dummy Mapping

Non-existing objects can be masked in the PDO mapping by dummy mapping entries. So it is possible to map objects from different devices into the same PDO. The dummy mapping entry includes the index of the basic data type, sub-index 0 and the size of the basic data type in bits.

Please note that dummy mapping entries must be enabled here before they can be used at the PDO mapping mask.

Example: The dummy mapping for an object of data type UNSIGNED32 is 0x00070020.

Other Settings

Dynamic Channels Support This setting specifies the facility of dynamic variable generation.
Group Messaging This setting specifies if the device supports the CANopen service MPDO.
"Group Messaging" = off: MPDOs are not supported
"Group Messaging" = on: MPDOs are supported
LSS Supported This setting specifies if the device supports the CANopen service LSS.
"LSS Supported" = off: LSS are not supported
"LSS Supported" = on: LSS are supported
Self-starting device (XDD) This setting specifies if the device is self-starting.
SDO Requesting Device (XDD) This setting specifies if the device is able to request a SDO connection from a SDO manager.
Granularity This setting specifies the minimum size in bytes of an object, which can be mapped into a PDO.
The Granularity has the data type UNSIGNED8.
"Granularity" = 0: dynamic PDO mapping is not allowed
"Granularity" = 1-64: dynamic PDO mapping is allowed with the minimal object size in bits

File Settings

File Name specifies the name of the EDS and XDD device description file. Device description files are generated for each CAN line.
