    Product overview Introduction EPP3204-0002 | 4-channel analog input Pt100 (RTD) The EPP3204 EtherCAT P Box with analog inputs allows resistance sensors to be connected directly. The module’s circuitry can operate the sensors using 2-, 3- or 4-wire connection techniques. Linearisation over the full temperature range is realised with the aid of a microprocessor.

    Version identification of EP/EPI/EPP/ER/ERI boxes The serial number/ data code for Beckhoff IO devices is usually the 8-digit number printed on the device or on a sticker. 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.

    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 62 Fig. 18: 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.

    Electronic access to the BIC (eBIC) Electronic BIC (eBIC) The Beckhoff Identification Code (BIC) is applied to the outside of Beckhoff products in a visible place. If possible, it should also be electronically readable. Decisive for the electronic readout is the interface via which the product can be electronically addressed.
