9.1 Configuring and commissioning CANopen

• Use internal module filters;
please consult manual "XN-300 Slice Modules", MN050002-EN.
• If you use the default mapping (index 0x6401/x), you can configure a
transmission filter for each individual payload object (SDO objects:
AI_DELTA_VALUE, index 0x6426/x).
When this filter is configured, the gateway will update and transmit
the corresponding value only if this value is different from the last
transmitted value by more than the configured delta.
By setting an inhibit time or selecting a synchronous transmission type,
TPDO properties can be configured in such a way as to avoid impermissible
bus loads .
9.1.5 Description files for CANopen
The gateway XN-312-GW-CAN is integrated into the CANopen structure with
the aid of a standardizes EDS file (Electronic Data Sheet).
This EDS file lists all objects with the associated sub-indexes and the corres-
ponding entries. The EDS file will be installed automatically in XSOFT-CODE-
SYS-3 with the CANopen master.
9.1.5.1 Standard EDS files
Make sure that you are working with the latest version of the standard EDS
files in your PLC programming environment. If modules are not listed, check
whether there are available updates for the files in the Download Center
￫ Page 8. To find it quickly, simply enter "XN300" or "EDS" as a search term.
9.1.5.2 Installing the EDS file
If you want to install an updated EDS file or an EDS file from another device
manufacturer, follow the steps below:
▶ Select and download the latest version of the EDS file.
▶ Save and unzip the "*.zip" file to a project folder of your choice.
▶ Click on the <Tools | Device Repository…> menu option in XSOFT-COD-
ESYS-3.
▶ Click on the <Install...> button.
▶ Use Explorer to select the EDS file you want.
▶ Confirm with click on <Open>.
▶ Click on "OK" on the "The device has been successfully installed" prompt.
NOTICE
The short data refresh cycle times in the XN300 system can
result in the CAN transmission path being subjected to high
loads. Accordingly, it is recommended to limit the data being
transmitted by using the various PDO properties available (e.g.,
inhibit time), especially in the case of analog input and technol-
ogy modules featuring counters.
