EJxxxx (s. note on documentation of ELxxxx [} 35]). 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. -
Page 9: Fig. 1 Order Identifier (A), Revision Number (B) And Serial Number (C) Using The Example Of Ej1008
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. -

Page 11: Beckhoff Identification Code (Bic)
1.7.1 Beckhoff Identification Code (BIC) The Beckhoff Identification Code (BIC) is increasingly being applied to Beckhoff products to uniquely identify the product. The BIC is represented as a Data Matrix Code (DMC, code scheme ECC200), the content is based on the ANSI standard MH10.8.2-2016. - Page 12 Example of composite information from items 1 - 4 and 6. The data identifiers are marked in red for better display: An important component of the BIC is the Beckhoff Traceability Number (BTN, item no. 2). The BTN is a unique serial number consisting of eight characters that will replace all other serial number systems at Beckhoff in the long term (e.g.
