EDS & DCF files
Last Updated a year ago

There are two types of electronic files used by most PLCs to configure the CANopen device parameters and the communication facilities. They are specified in CiA306.

1 Electronic Data Sheet (EDS)

EDS files are used to describe CANopen parameters:
  • Communication parameters as defined in /CiA301/
  • Application parameters as specified in CiA® device and application profiles
  • Manufacturer-specific parameters as defined by the device manufacturer.
An EDS serves as a template for configuration of the one device type. By such a template a vendor describes CANopen parameters for the non-configured CANopen device.

You can download EDS files for your sensor here:

Use this document to look up the EDS file you need:

An EDS file can be opened by an CANopen software, for example Vector CANeds etc. You can easily see the structure of an EDS file like this:

DIS EDS file contains already default values for some parameters. It happened before our EDS file contains fault default values, when PLC use the EDS file, the sensor is initialized to SYNC mode, or TPDO1 is disabled. We are now checking all EDS files online to make sure right default values are set.

If you don’t have those software, you just want to study it, you can also open it with MS Excel, you will see the same structural content in the sheet.


2 Device configuration file (DCF)

DCF files are used to describe CANopen parameters with values for the configured CANopen device as illustrated in figure below. The DCF shall be structured the same way as EDS for this CANopen device.


DCF files are on request, it is not supplied as standard service. You can also generate the DCF file by yourself with CANopen software. Once you received sensor, first save the configuration to a DCF file, you might use this file in the future to restore your sensor.

Example, with PCANopen Magic ProDS:
