除了 BACnet/IP，倍福的 EtherCAT 端子模塊 EL6861 現在還支持 BACnet MS/TP(主從站/輪詢傳遞)。該串口模塊可用于直接控制和監測兼容 BACnet 的現場設備(作為子系統)，如泵、驅動、變頻器或類似設備，無需使用額外的網關或路由器。最多可以連接 64 臺帶 BACNet MS/TP的設備。此外，多個端子模塊可以同時運行，可以根據 S/TP 的設備數量來調整。
使用單通道 BACnet MS/TP 接口可以顯著降低硬件和工程成本，因為配置全部在 TwinCAT System Manager 中集中進行，無需連接諸如路由器或網關等外部設備。端子模塊支持 BACNet Rev 12標準，可以集成在 TwinCAT 自動化軟件內的 BACnet MS/TP 驅動程序直接使用。端子模塊也無需路由到 BACnet/IP 網絡，在現場層可以直接通訊。
The BK2000 Bus Coupler connects the Lightbus system to the electronic terminal blocks, which can be expanded in modular fashion. One unit consists of one Bus Coupler, any number of up to 64 terminals and one end terminal.
The Bus Coupler recognises the connected terminals and automatically generates the affiliations of the inputs/outputs to the bytes of the process image. The first input/output signal is inserted in the first bit of one byte (LSB), beginning from the left. The Bus Coupler inserts further signals in this byte. Inputs and outputs are clearly separated. The Bus Coupler automatically begins a further byte if the number of inputs or outputs exceeds 8 bits.
The Lightbus System is a rapid and safe serial fieldbus system. The Lightbus has a ring structure; up to 254 stations can be operated in a ring. Easy-to-operate standard fibre optic technology is used for data transmission, which represents excellent value. Thanks to an optimised, efficient telegram structure, the Lightbus achieves a very high user data transmission rate. For the exchange of 32 bit information 25 μs transmission time is required.
Thanks to the high-speed access method employed by the Lightbus, it is possible to access specific peripheral data and to read or write the required data only. Data is exchanged with the required priorities without producing any overhead.
