The Allen Bradley MobileView tethered operator interface gives plant personnel the freedom to take a machine’s human-machine interface (HMI) with them to make real-time adjustments to out-of-view applications. The MobileView suits maintenance tasks, machine setup or calibration activities, and other HMI applications that require the operator to see the machine. The inclusion of a hardwired e-stop button and three-position enabling switch also supports applications that require local safety functionality.
