Rich's letter: 

Dear editor:
I’ve been a PR flack for 20+ years, and I’ve NEVER used the word “breakthough” to describe a client’s product. (I admit to once using “paradigm shift” back in the 1980s, and for that I apologize).
As you know, most products are not breakthroughs, best-in-class, state of the art, award-winning, or leading edge, except in the mind of the vendor’s PR people.
But this time I have such a breakthrough product! The Console Recorder from Longwatch is a virtual time machine, a software package that lets companies see what the operator was watching on the HMI when the plant blew up. It records the video signal to the HMI and archives it, so companies can see exactly what happened during an alarm, explosion, plant upset, leak or any other event.
If three monitors are available, the company can put archived plant video on one screen, display what the operator was watching on another screen, and show data from the historian on a third screen—in other words, the company can reconstruct the EXACT situation as it occurred in the control room at the time of the incident.
I will leave it to your fertile editorial imagination to consider what this might mean in terms of legal implications, accident investigations, event reconstruction, regulatory concerns, training, operator procedures and process control/automation in general. I am with child in anticipation of reading what you might say.
If you want to discuss this with Steve Rubin, president of Longwatch (and the person who invented PC-based control in the first place), call him directly at (781) 255-7400 x200.
Attached and appended below is the “breakthrough” news release from Longwatch describing its Console Recorder HMI software.

Longwatch Introduces Operator’s Console Recorder
Video software records exactly what was on HMI screens when an event occurred, archives it, and plays the video back for training or analysis purposes.
Norwood, MA—September 11, 2009—Longwatch announces 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.
For example, in the case of a leak at a pumping station, investigators could watch plant video taken at a remote site showing fuel oil creeping across the floor of a pumping station, real-time data being acquired from pumps, valves and the receiving tank while the leak is occurring, what appeared on the operator’s HMI screen, and the alarm screen that came up when the leak detector went off. Investigators can then watch the operator switch the HMI screen to live video feed from the pumping station, observe the leak, and take action from the HMI to shut off the pump. Plant video would show the arrival of a maintenance crew to repair the leak. Analysis of all data and videos might show that the leak detector was poorly positioned and an alarm condition is needed for when fuel oil is being pumped but is not being received at the storage tank.
With a typical three-display system, as found in many process control applications, it would be possible to display remote pump video on one screen, video from the operator’s display at the time of the event on a second screen, and process historian data on a third screen, thus getting a simultaneous view of what happened and what the operator saw.
To help mitigate insurance and regulatory issues, the combined video and historian information could help determine that the operator acted correctly and the spill was cleaned up with no damage to the environment. The Longwatch Operator’s Console Recorder and Video Historian fills the gap between normal plant data acquisition and actual plant management, because it shows everything that happened during an event; i.e., what actually happened, what the data acquisition equipment monitored and recorded, and what was reported to the operator on the HMI screen.
Capturing the actual video feed to the operator HMI is a much better solution than traditional methods, says Steve Rubin, president of Longwatch. “Before Longwatch, recording and playback of an operator’s HMI was clumsy and limited. One method was to put a camera over the operator’s shoulder. This is intrusive and intimidating, and the camera has a limited ability to read what’s on the screen,” he explains. “In an installation with multiple HMIs, this solution would require a camera on each screen.”
Another method is to use process historian data. “It’s possible to recreate the console display the operator should have been watching by driving it with data from the process historian,” says Rubin. “This requires the historian to record all the data values present on every display. However, no one knows which screen an operator was actually watching at the time of the event. An operator could have been looking at a trend display, not the alarm summary screen.”
With the Longwatch system, there is no problem reading the screens, and no doubt which screens operators were watching. By combining video data from plant locations, video from HMI screens, and data from the historian, investigators can go back in time to see exactly what happened and make a better analysis of what to do about a similar situation in the future.
