X20 bus controller for Modbus/TCP

10/23/2006

B&R has developed a Modbus/TCP model based on the X20 bus controller. ETHERNET Powerlink is 100% software-based, so the same hardware can be used. Ethernet/IP and Profinet RT models are in preparation. The Gigabit Ethernet bus controller developed by B&R will also be available for these open Ethernet protocols, which do not require an ASIC.

To transfer or receive I/O data on the fieldbus, the bus controller does not need to be programmed. It works simply by configuring the fieldbus master.

With the X20 bus controller, B&R continues to follow the completely modular strategy of their I/O slices. The most compact Ethernet bus controller available on the market has a width of a mere 37.5 mm. Made up of a base module, a supply module to supply the voltage for the entire system, and a fieldbus interface, the bus controller is an extremely flexible fieldbus connection. The entire bus-independent backplane can be preinstalled. Pre-wiring is also possible thanks to the removable terminals. Two RJ45 interfaces make economical daisy chain wiring possible.
