Keeping an eye on the process…
Our factory automation and process control systems generally incorporate operator interfaces, from single graphics based screen's, to redundant servers running factory wide suites of screens spanning multiple control rooms. We have applied multi-node networked visualization systems providing information for use by MES and ERP schemes. These required efficient database creation, data manipulation and management to optimise production yields and volume.

Supervisory Control & Data Acquisition (SCADA)
The application of solutions involving a SCADA system and PLC or PCS technologies from a single automation supplier, or the provision of a disparate controller and SCADA system from a specialist SCADA software developer.

Human Machine Interfaces (HMI)
Graphics based or pushbutton and lamp type, operator control panels. Suitable for installation in designated safe areas or certified hazardous areas with appropriate ATEX certification.
Alarm annunciator panels for safe areas or certified hazardous areas.

Alarm Management & handling
With many of our systems managing safety critical plant, we understand the consequences of a failure and the alarm(s) that result. We ensure our information systems provide concise and unambiguous alarm information to site personnel, so they can facilitate appropriate action.

We appreciate that a single failure can give rise to numerous alarms, and that the careful prioritisation of alarm signals must be undertaken to avoid so called "floods" of alarm signals. Such "floods" can easily distract or swamp site personnel, resulting in them missing "critical" signals, or acting upon less important information.

Integrating control systems in accordance with IEC61508/IEC61511 has lead us to appreciate the human factor aspects, which form the part of any control system. Accordingly, for each project we ensure the handling and presentation of data is carefully assessed to ensure adherence to EEMUA 191 (Alarm Systems, A Guide to Design, Management and Procurement).
