2 Operational description
The B&R wireless board “RFM-2-NF” is used to add basic RFID functionality to a B&R Human-Machine-
Interfaces and is integrated in a B&R Automation panel with or without optional expansion equipment (here
called host). The electrical connection is realized via a host interface. The host in combination with the
auxiliary equipment provide an isolated power supply and realize the data exchange between host and
wireless board. The combination host plus auxiliary equipment act as master. The SRD controller enables
the B&R wireless board “RFM-2-NF” to communicate with various passive transponders (TAG). The RF-
control sequence depend on the type of transponder used. Details of supported transponder types and
corresponding standards are listed below.
A B&R Human-Machine Interface can be realized by combining a B&R Automation Panel with optional
extensions for e.g. push buttons and key switches and different auxiliary equipment like Panel PCs, B&R
Automation PCs, Display Links, power supplies, data and power supply cables plus optional accessories
like flexible swing arm mounting systems and handles. So a variety of Human-Machine-Interfaces are avail-
able, but the RFID functionality is exclusively realized by the B&R wireless board “RFM-2-NF”.
The end devices containing the RFM-2-NF are operated exclusively in an industrial environment. The main
nominal RF characteristics are 13.56 MHz, low power device and short range of 2-10 cm.
The following conditions and constructional data apply:
 General (-20°C to 55°C
 Portable (-10°C to 55°C)
 Equipment for normal indoor use (0°C to 55°C)
