Data structure
The Gateway can be configured through the software WINGATE
®
that is also supplied.
This Gateway module from the UNIGATE range of Deutschmann Automation allows a coupling
between
PROFIBUS DP
and
CANopen
®
.
Here the Gateway on the CANopen
®
side acts as a standard-compliant master and on the Profi-
busDP side as a standard-compliant slave so that the problems that appear again and again (to
couple the CANopen
®
Slave participant to a Siemens PLC with ProfibusDP) are solved.
Data transfer
The data exchange between the Profibus and the CANopen
®
will be fixed with the Mapping
which is configured via "WINGATE
®
".
Mapping means the illustration of data of one fieldbus to any other fieldbus. As data all data can
be used which are made available from the corresponding busses.
The Mapping works in both directions from the Master to the Slave as well as reverse.
Example:
That way it can be defined that the 2nd byte of the COB-ID201 (CANopen
®
-participant) is
transfered into the Profibus data as 7th byte.
At present 256 mappings are possible (128 Tx and 128 Rx Mappings). The data is transferred as
PDOs only. You can setup maximum of 16 Tx and 16 Rx PDOs. Each PDO can have up to 8
bytes (means 8 mappings). 16 PDO * 8 byte = 128 mappings. SDO accesses are also supported
(see chapter 14.3.1.10)
14.3.1.1 Configuration of the mapping
In order to create or work on such a mapping, please connect the UNIGATE with the PC via the
RS23-interface and there start the software "WINGATE
®
".
After the start of the software an upload from the connected device will be carried out automati-
cally. The corresponding matching parameters to this device are displayed. Select the CANopen
Mapping protocol and look for the entry "(CM) Profile" in the table and click doubled onto the
value "map ...". After a short period a dialogue is displayed. With it, it is possible to process all
map entries (similar to the following picture):
