    Since received data normally cannot be repeated by the transmitter, they have a higher priority in the module than data to be transmitted. Furthermore, the priority decreases as the channel number increases. Hence, the reception of data on channel 1 has the highest priority. EPP6001-0002 Version: 1.3...

    6.3.3 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 61 Fig. 26: Example DMC 1P072222SBTNk4p562d71KEL1809 Q1 51S678294 An important component of the BIC is the Beckhoff Traceability Number (BTN, position 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.
