Historically lamp annunciator arrays were the defacto method of communicating operating status and alarms information from control systems to operators, with moving needle gauges for monitoring of analogue signals. 

Matrix displays were used for complex process or system diagrams, taking up large areas within the control room or equipment room.

As part of a wider control system upgrade these lamp annunciators can be replaced with modern, intuitive interactive PC-based displays with increased functionality in a much reduced space. Running industry standard software HMI applications with customised scalable mimics and screens to suit your application allows us to integrate the functions of basic and advanced machine controls, annunciation of deterministic messages, trips and alarms and trending of analogue instruments.

Using a PC-based HMI solution allows much greater level of information to be displayed to the operator, technician and engineer alike. With intuitive and interactive diagrammatic mimics, each device or instrument is clearly laid out in the correct functional location.

With built in graphical trending of key instruments and signals fault finding is greatly enhanced as the data can be watched in real time, paused and rewound back to a historic event, zoomed in and printed out if a suitable printer is connected.

Alarm annunciation is clear and descriptive, each entry in the annunciator is time and date stamped with the identifying tag of the device and a conditional description of what the source of the message is, giving precise information as to the causal nature of the message.

The annunciator record is stored in an archive, to be recalled during investigation of historical events and can be cross-referenced with any instrumentation trend data recorded. Using an optional GPS-based synchroniser the time stamps of multiple HMI’s and controllers can be guaranteed to be “in sync” with each other.

By using touch screen technology, the usual myriad of push buttons, selector switches and lamps can be eliminated from the front of the control system. By implementing a multi-level password protected access system, the right level of data can be displayed to the right personnel and adjustments can only be made by suitably authorised staff.

We can help if your unsupported existing HMI fails – A UK customer sought our help when an HMI screen on one of their safety protections systems failed – the original equipment supplier was no longer in business. We were able to re-engineer their existing HMI application into new hardware, upgrading the software application to the latest version to ensure continued reliable operation.
