Mobile Panel

Designed for safety-oriented applications, the 277F IWLAN mobile panel from Siemens communicates via a Rapid Roaming process ensuring interruption-free transmission of the wireless signals. This guarantees fast handover of the radio signals between access points and interruption-free roaming times - a basic requirement for mobile operator control and monitoring in safety-related areas where enabling and emergency stop buttons are used. The device combines a color display of the WLAN signal strength with a vibration alarm, which is triggered when a specific lower limit threshold is violated. It is suitable for use in a Profinet-based network with a Profisafe profile and IWLAN infrastructure with Scalance W access points.
