Product Description:
The 2NW100.59-010 is a system module manufactured by B&R Automation for the System 2010 Controllers series. Installed in a single-width slot of the central rack, it provides a dedicated PROFIBUS interface that allows the controller to coordinate distributed I/O, motion axes, and safety devices over a common fieldbus. By handling cyclic data exchange and diagnostics at the network layer, the module offloads communication tasks from the CPU and streamlines integration of automation cells.
Its power draw is fixed at 15 W, allowing enclosure power supply sizing to remain predictable. Two communication ports employ electrically isolated RS-485 transceivers, and galvanic isolation protects against differential ground potentials that can occur between remote stations. Network arbitration relies on the token-passing master/slave method, so only the node holding the token initiates transmission and deterministic cycle times can be maintained. A maximum of 127 stations can participate on one segment, giving broad installation coverage without repeaters. Compliance with DIN 19245 Parts 1 and 2 ensures telegram structure, timing, and error handling match standard PROFIBUS-DP implementations, while direct bus coupling to the backplane removes intermediate cabling and reduces contact resistance.
The housing occupies 40 mm of rack width, extends 185 mm into the cabinet, and stands 285 mm high, so dense packaging of control hardware is possible. Field wiring uses a shielded twisted 2-wire medium arranged in a linear bus, keeping electromagnetic interference low over long runs. Selectable data rates of 9.6/19.2/93.75/187.5/500 kbit/s allow the network length and update speed to be matched to the application. An auxiliary isolated supply of 5 VDC at 200 mA powers the internal opto-isolation circuits, maintaining separation from system logic power. The module’s single-width construction aligns with adjacent CPU and power cards, preserving airflow paths inside the enclosure.
