3.8.1 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 29 Example of composite information from item 1 to 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.

Page 42: Using Restore File
5.2.5 Using Restore file Restore files are used in the Beckhoff device manager for saving existing EtherCAT Terminal configurations and settings. Without a Restore file, EtherCAT Terminal settings are lost, if the terminal is replaced. If a Restore file was created, the parameters can be copied to a new EtherCAT Terminal when the Bus Coupler is started. -
Page 43: Configuration In Twincat 3
5.3.1 Adding the EK3100 Bus Coupler in TwinCAT The EK3100 Bus Coupler is added in TwinCAT under a PROFIBUS master. In this step the CX2020 Embedded PC is used with a CX2500-M310 PROFIBUS fieldbus module as an example. The EK3100 Bus Coupler requires the appropriate GSD file for TwinCAT. Two options are available. The GSD file can be copied into the TwinCAT directory or added to TwinCAT retrospectively. -

0x10 E-bus fixed after error. Outputs are disabled and have to be reset manually with the control DWORD. 0x04 E-bus error. In the event of an E-bus error, the EK3100 Bus Coupler continues to exchange data with the PROFIBUS master. However, the input data are invalid. The cause of the error is coded in the high byte, the position in the low byte of the counter. -
Page 45: Adding An Ethercat Terminal
Adding an EtherCAT Terminal Please note the order of the EtherCAT Terminals in TwinCAT. The EtherCAT Terminals have to be added to TwinCAT in the same order as they are plugged or addressed by the EtherCAT master (EK3100 Bus Coupler). -
Page 46: Creating A Virtual Slave
5.3.4 Creating a virtual slave Up to three virtual slaves can be configured for the EK3100 Bus Coupler. Virtual slaves can be used to increase the transfer rate beyond the standard PROFIBUS rate of 244 bytes. The maximum process data size is 240 byte inputs and 240 byte outputs per slave. - Page 47 Configuration ð Add all EtherCAT Terminals after the EK3100 Bus Coupler and the virtual slave.

Page 49: Accessing Coe Data With Dpv1 Services
The COE data must allow READ and WRITE access. For read and write access to COE data, the DPV1 service must be active on the EK3100 Bus Coupler in the parameter data for the EK3100 Bus Coupler. In TwinCAT you can control whether the DPV1 service is active, or you can activate the DPV1 service. - Page 50 Configuration ð You have successfully activated the DPSV1 service.
