The VisuNet RM Shell thin client firmware is pre-installed on every VisuNet Remote Monitor (RM) and box thin client. It is engineered to simplify thin client setup and operation of virtualized and conventional workstation-based process control systems. The firmware replaces the Windows desktop and reduces the user interface to critical system functions. Predefined user roles (administrator, engineer and operator) provide tailored information access to different authorization levels. An app concept allows integration of third-party remote protocols and applications, which enables OEMs to integrate their own apps and adapt the firmware to their own automation infrastructure.
