Setup and use
The setup of the PN/CAN Gateway is divided into 3 steps:
1. Transfer EDS or DCF file to the PN/CAN Gateway:
The EDS or DCF file contains the description of all SDOs, their default values of all CAN objects
(SDOs) and basic settings of the CANopen Device. The file will be defined by the customer and has to
be uploaded after changing. It will be stored by the PN/CAN-Gateway in the flash memory
permanently.
2. Parameterize the PN/CAN Gateway in the hardware configurator:
The GSDML file is used to insert the PN/CAN Gateway in the PROFINET engineering tool into the
PROFINET network and to define which SDOs are to be exchanged with the PLC.
3. Programming in the PLC:
In the PLC, the state and behavior of the PN/CAN Gateway can be read and controlled via the I/O
image. The data of the SDOs are also located in the I/O memory according to the configuration.
Handling blocks are not necessary.
6.1
Transfer EDS or DCF file to PN/CAN Gateway
The PN/CAN Gateway is freely configurable as a CANopen device as far as possible. With the import of
an EDS or DCF file it is defined which SDOs the PN/CAN-Gateway
should support and also the most of the CANopen properties are
defined in the file.
An example EDS file for a simple IO-Slave according
to CiA standard DS401 ("DS401_IO_Slave_Vxx.eds")
can be downloaded from the Helmholz website in
the download area of the PN/CAN-Gateway in the
section "Software":
The file can be customized in a normal text editor. But there are also
special EDS editors, e.g. "Vector CANeds" or "CANopen Architect"
which can be used for editing the EDS file in a limited way.
The content of the EDS file is in the document "CiA 306: Electronic
Device Description (EDD)", which can be downloaded from the CiA
website:
https://www.can-cia.org/can-knowledge/canopen/cia306/
On the right side of this page is a section of an EDS file.
The DCF file is a special variant of the EDS file, which in addition to the
basic description of all objects and parameters already contains preset
values of a concretely configured CANopen device, as well as the Node-
ID and the bit rate. For a EDS file, the Node-ID and the bit rate will be
defined in the PROFINET configuration.
