Everyone is looking for ways to optimize and save money in these tough economic times, so using standards like OPC makes even more sense (or cents for that matter). There’s an OPC Foundation article on this topic posted over at AutomatedBuildings.com that focuses on OPC in building automation. The home and building industry uses a lot of protocols, like BACNet and Johnson Controls N2. Using OPC to tie these devices to building management systems can lead to a lot of savings.
If the ‘green’ movement isn’t enough reason for more building automation vendors to leverage OPC standards, may be the economic crunch will be. Those wanting more information on using OPC with building automation can check out these papers: If These Walls Could Talk or Integrating OPC into Building Automation.
