4.5.1 EDS file
PowerXL devices can be integrated into a CANopen structure by using a
standardized EDS (Electronic Data Sheet) file. EDS describes the
functionality of a CANopen device in a machine-readable format. EDS files
list all objects, the supported baud rates, the manufacturer, and other
information as well.
The object dictionary contains all the objects corresponding to a CANopen
module. Objects are used to map a device‘s functionality/parameters.
They are accessed with SDOs or PDOs. As per the corresponding
specification, the object dictionary is subdivided into the following ranges:
Table 14: Object dictionary ranges
The object dictionary contains the entries described below.
4.5.2 Transmission Type
