1.7 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).

-9414 (with ECT, STO and TwinSAFE SC)
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.

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.
Fig.3: BIC as data matrix code (DMC, code scheme ECC200)
The BIC will be introduced step by step across all product groups.
Depending on the product, it can be found in the following places:
• on the packaging unit
• directly on the product (if space suffices)
• on the packaging unit and the product
The BIC is machine-readable and contains information that can also be used by the customer for handling and product management.
Each piece of information can be uniquely identified using the so-called data identifier (ANSI MH10.8.2-2016). The data identifier is followed by a character string. Both together have a maximum length according to the table below. If the information is shorter, it shall be replaced by spaces. The data under positions 1-4 are always available.
The following information is contained:

BTN
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. batch designations on IO components, previous serial number range for safety products, etc.). The BTN will also be introduced step by step, so it may happen that the BTN is not yet coded in the BIC
Notice
This information has been carefully prepared. However, the procedure described is constantly being further developed. We reserve the right to revise and change procedures and documentation at any time and without prior notice. No claims for changes can be made from the information, illustrations and descriptions in this information.
