Video Software Records HMI Screens During Alarms, Explosions

Longwatch recently announced the Operator’s Console Recorder, a software module that automatically records images being shown on multiple HMI or SCADA operator’s displays. The module takes its signals directly from each HMI screen’s video software driver, so it records the actual video being sent to the HMI. The software can accommodate video signals from an unlimited number of HMIs to show what operators were watching at the time of an event, alarm or process upset.

Video images can be combined with the automatic data mapping capability of Longwatch’s Video Historian, so the Console Recorder can automatically retrieve and replay operator displays simply by clicking on a time-based alarm or system message. Playing back what the operator was seeing at the time of an event can be a valuable tool for training and analysis purposes, and can help mitigate insurance and regulatory issues by eliminating guesswork and conjecture.

Videos used for monitoring plant activities can also be combined with the operator console videos and data from a process historian. This enables engineers, analysts or investigators to see what was happening in the plant, what the operator was seeing on the HMI screen at the time, and all relevant real-time data that occurred at the time of an event.
