Trip Analysis System

In order to determine the root cause of an emergency shutdown of a plant caused by failure or the like, a trip analysis system can support the analysis of the failure by collecting the events and sequence data around the time when a major piece of equipment of the plant trips.
This system is offered by using components of DIASYS Netmation.

• Post trip log function
  When a major piece of equipment of the plant trips, this function collects the data of the pre-registered analog and digital signals around the timing of the trip and prints out the data. By collecting and printing out the process data around the timing of the trip, it supports the investigation and analysis of the root cause.
• SOE report function
  When a major piece of equipment of the plant trips, this function prints out the high-speed events and the data recorded in the event trace(Note) around the timing of the trip. By displaying the process data around the timing of the trip in chronological order in high precision, it supports the investigation and analysis of the root cause. (Note) Event trace The event trace is used to record alarm events, operations on operator stations, and logic monitoring adjustment operations. (The timestamp resolution is one second.)
• Flight recorder
  When a major piece of equipment of the plant trips, this function collects the data of the pre-registered process values around the timing of the trip and displays the data on a trend graph.
