The HMI subsystem of TSENTRY is designed to provide as much common functionality as possible to the user while maximizing flexibility for a given system. Not only does TSENTRY provide a common set of useful management and diagnostic screens such as ProbeX and TrendX, it also provides a set of tools to allow the user to develop his own HMI screens and easily connect them to the host TSENTRY system.
Within TSENTRY HMI screens are divided into groups called HMI Applications. Each HMI Application is governed by a set of rules defined in the configuration file for that application. These rules specify application options such as which users are allowed to access which screens, which screen should be displayed by default, which languages are supported within the screens, and so on.
All HMI Applications in TSENTRY are viewed using the TSENTRY Screen Explorer, or Texplore, which acts as a container application for displaying and navigating between HMI screens. Texplore uses the various services to exchange information with the TSENTRY host in order to provide a secure yet highly customizable front end to any control system.
