Two apartment blocks in downtown Rio de Janeiro use bespoke building automation systems based on CC-Link, a fieldbus communication system originally designed for industrial automation applications.

Within the Bernini buildings, the automation systems control fountains, water gardens, a swimming pool, a sauna, air conditioning and ventilation, lighting, security and access and a range of other functions.

Cetem Automação Industrial installed the industrial automation technology, including CC-Link fieldbus communications, claiming that they would be cheaper, more reliable, more flexible in light of inevitable future changes and easier to install and commission than a conventional building solution.

The architecture of the control systems is the same for each of the Bernini towers — both consist of a Mitsubishi FX controller along with a CC-Link Network Master. Each CC-Link network consists of four stations, all connected and controlled from the single FX controller control station located on the first floor.

Key benefits of product application

  • The use of automatic controls ensures the correct operation of the building systems, cutting down on personnel and thus reducing costs.
  • The CC-Link networking reduces electrical wiring installation costs and provides increased system and building diagnostics that provide important data for the maintenance staff to improve the overall maintenance and safety of the entire facility.
  • The use of the CC-Link network, requiring only a single communication cable to connect the fan to the control on different floors of the facility, saved many man hours during the installation of the building automation system and simplified commissioning.
  • The lighting control system, connected via CC-Link networking, provides an extra level of safety by automatically providing sufficient light for security monitoring without personnel having to turn lights on or off.
  • The installation of panic buttons throughout the public areas provides an extra level of security to the building occupants. The use of CC-Link networking to connect these panic buttons allows security personnel to pinpoint the location of the activated panic button and provide fast response.

CC-Link Partner Association (CLPA)

The CLPA is the organisation of manufacturers of CC-Link compatible products and users of CC-Link technology. The CLPA oversees and manages the CC-Link specifications, provides technical support and conformance testing and promotes the worldwide adoption of the CC-Link open automation network technologies. The CLPA was formed in November 2000. Global adoption of CC-Link is demonstrated by the following:

  • Over 12 million CC-Link devices have been installed
  • There are more than 2,100 members of the CC-Link Partner Association
  • There are more than 1,300 certified CC-Link products available from over 280 manufacturers

CC-Link is acknowledged by third party research to be the leading choice for open automation networks in Asia. By adding CC-Link to their portfolio, companies will be able to access up to 20% of the Asian market not accessible to Western technologies. To assist companies with this, the CLPA offers the “Gateway to Asia” (G2A) programme, G2A provides development and marketing assistance to companies who join the CLPA and develop CC-Link products.
