Marking of EtherCAT plug-in modules

Designation

A Beckhoff EtherCAT device has a 14-digit technical designation, made up as follows (e.g. EJ1008-0000-0017)

  • Order identifier
    • family key: EJ
    • product designation: The first digit of product designation is used for assignment to a product group (e.g. EJ2xxx = digital output module).
    • Version number: The four digit version number identifies different product variants.
  • Revision number:
    It is incremented when changes are made to the product.

The Order identifier and the revision number are printed on the side of EtherCAT plug-in modules (s. following illustration (A and B).

Notes

  • The elements mentioned above result in the technical designation. EJ1008-0000-0017 is used in the example below.
  • EJ1008-0000 is the order identifier, in the case of “-0000” usually abbreviated to EJ1008.
  • The revision -0017 shows the technical progress, such as the extension of features with regard to the EtherCAT communication, and is managed by Beckhoff.
    In principle, a device with a higher revision can replace a device with a lower revision, unless specified otherwise, e.g. in the documentation.
    Associated and synonymous with each revision there is usually a description (ESI, EtherCAT Slave Information) in the form of an XML file, which is available for download from the Beckhoff web site.
  • The product designation, version and revision are read as decimal numbers, even if they are technically saved in hexadecimal.

Serial number

The serial number for EtherCAT plug-in modules is usually the 8-digit number printed on the side of the module (see following illustration C). The serial number indicates the configuration in delivery state and therefore refers to a whole production batch, without distinguishing the individual modules of a batch.
