Product Description:
The 2EX100.50-1 is a communication controller that integrates into the System 2010 Controllers series from B & R Automation. Installed beside the CPU on the common backplane, it provides a dedicated fieldbus interface. This lets the host controller exchange deterministic data with distributed I/O stations used in material-handling cells, assembly lines, or other coordinated motion segments of an automation plant.
The module handles bus arbitration according to the Master/Slave Principle, and it presents two independent channels through 2 x RS485 ports. Each channel is routed to the front panel through 2 x 9-Pin D-Type Sockets, simplifying connection of standardized field cabling. Communication speeds can be selected in software up to 1000 kbit/s, so the bandwidth can be matched to cycle-time requirements. The electrical load on the controller’s 5 V backplane supply does not exceed 12 W, allowing dense node clusters without overloading the power budget. Bus wiring is attached directly to the housing, so no intermediate plug-in terminals are required and insertion losses are minimized.
Upstream, one CPU can coordinate as many as 8 remote I/O masters, and each master may supervise up to 31 without repeater subordinate stations before signal regeneration is required. The unit snaps onto a base plate such as BP101, where the physical bus uses Shielded, Twisted Pair cabling to improve immunity against electromagnetic interference. The topology follows a physical bus layout, so every station is wired in series and end-of-line integrity is maintained with an external termination resistor. This arrangement supports larger System 2010 installations while maintaining stable data transmission across the plant floor.
