General information
•
The basis for working with the CANopen node is the object dictionary (OD) of a node
that is usually made available by the manufacturer as an EDS file.
•
You can import an existing EDS file by clicking on the "Import EDS file..." button. If no
EDS file is available yet, create the object dictionary (OD) manually. To do this, use the
"Define object dictionary" button. Both steps will result in an object dictionary (OD).
•
The import of an EDS file can take several minutes depending on the size and
complexity of the file. You can significantly shorten the time required for the import by
reducing the EDS file to just the entries that are actually needed.
For users of the firmware version V1.0
•
Once the EDS file is imported, all necessary information is part of the TIA Portal project
so that the EDS file is no longer needed.
•
To edit an EDS file properly, you need to know the structure of the EDS file well or use
a specific EDS editor.
•
Data from the EDS file cannot be updated at a later time. If the EDS file needs to be
imported again due to changes (e.g. corrections), you must delete the node and create
it again.
•
Check the object dictionary (OD) of the CAN device for completeness and correctness.
We assume hereafter that the OD can be used without changes.
For users of the firmware version V2.0
•
The object dictionary (OD) is no longer write-protected so that you can edit, add and
delete entries.
•
An imported EDS-file creates an object dictionary (OD) that can be used immediately.
However, you must confirm a manually created object dictionary (OD) by pressing the
"Apply and check data" button.
•
As of V2.0, you can correct any incorrect OD entry directly without deleting the node.
•
Relationship between an OD and configuration menus:
You perform the entire configuration in the corresponding menus and
not
in the OD
table. Settings from the menus are
not
visible in the OD table. You can find additional
information in the section "Handling of the OD table" below.
