CANopen

The manufacturer's ID, the device ID and any functions supported by a field device are de-
fined in a device description file. The device description file (Electronic Data Sheet, EDS) is
fieldbus-dependent. The content and format of a device description file are specified in the
fieldbus standard. The file is needed in order to include an unknown field device in the re-
spective fieldbus configuration tool and in order to configure the plant-specific require-
ments.
An EDS file in a standardised text format is used for CANopen devices.

Translation tables

Only Register 4x is represented in the tables. The same assignment applies for Registers
0x, 1x, and 3x.
