SCADA & PLC Control System for Integrated Building Management

Project Background

Banks and users of data centres are demanding higher availability from their BMS (Building Management Systems) as the equipment that they control – such as cooling, air-conditioning and fire and gas detection are critical to the operation of the facility.

Banks are dependent on the quality of the environment and the robustness of their systems as part of their qualification for their banking licence.

To meet the high availability requirements (typically availabilities above 99.5%+), designers are now specifying the same industrial PLC and SCADA equipment which offers these capabilities as standard features.

Solution Delivered

Working with Eon Control Solutions Ltd. a BMS vendor, AIS have designed and delivered the PLC and SCADA interface software for two systems – including:

• Deutsche Bank in London – covering the BMS for their London HQ incorporating their trading floor.

Google Data Centre in Eemshaven in the Netherlands.

The systems delivered use a combination of high availability and standard distributed PLCs and I/O equipment – linked to each other and a standard SCADA Head End via industrial Ethernet.

The PLC based BMS Interfaces to chillers, boilers, pumps and fans, valves and dampers, water sprinkler systems, air handling units, air conditioning systems, weather stations plus fire & gas detection.

Using communications interfaces that include: Hardwired I/O, Modbus TCP/IP and RTU, Bacnet MS/TP and IP. This provides control of temperature, pressure and relative humidity.

AIS Added Value as Control System Integrators

  • Knowledge of the design and build of high availability and distributed PLC control systems
  • Integration of systems within the BMS environment – bringing industrial grade systems and high availability architectures to BMS technology
  • Flexible approach to delivery – based on rapid application development – where software is developed, tested and refined in a series of stages in parallel with the development of the BMS requirements and systems
