Experion Station-TPS (ES-T) The Experion Station-TPS (ES-T) node provides the same operations environment as other types of Experion Stations. Experion Stations have the ability to use html for custom graphics and presentation of alarms, events, and messages.ES-T provides the Native Window application that emulates a Universal Station and optionally supports GUS displays. The Native Window and GUS connect to a locally installed LCNP (LCN processor) board, providing a user interface with access to all TPN/LCN operations, engineering, and maintenance functions.
