Fieldbus: Modbus/TCP, Modbus/UDPI/O configuration via the fieldbusDHCP-capableBootp-capableIntegrated double switch for efficient cablingConfigurable I/O cycle (0.5 to 4 ms)Response time: <1 to 8 ms (depending on the load on the integrated switch)Validity check for command sequences before execution Established in 1979, the Modbus protocol has approved the use of Ethernet with both Modbus TCP and Modbus/UDP. Today, Modbus TCP is an open Internet draft standard introduced by Schneider Automation to the Internet Engineering Task Force (IETF), the organization responsible for Internet standardization. The Modbus services and object model have been preserved since the original version and left unchanged for use with the TCP/IP transmission medium. Modbus/UDP differs from Modbus TCP in that it uses connectionless communication via UDP/IP. The advantages of faster and easier communication with UDP/IP also brings with it the disadvantage of requiring error detection and correction in the application layer.This bus controller makes it possible to connect X2X Link I/O nodes to Modbus via Ethernet. The bus controller can be operated on B&R controllers through the use of Automation Studio or on third-party systems with Modbus TCP or -UDP master functionality.With multifunction modules, the bus controller supports only the default function model in the event of automatic configuration by the bus controller (see the respective module description). All other function models are supported when configured accordingly in Automation Studio V4.3 or later. Automation Studio kann kostenlos von der B&R Webseite www.br-automation.com heruntergeladen werden. Die Evaluierungslizenz darf unentgeltlich zur Erstellung vollständiger Konfigurationen der Feldbus Bus Controller benützt werden.
