Building Automation
Building owners today are faced with an ever-increasing number of intelligent systems that are being installed in their buildings. These systems are not limited to HVAC systems. They include environmental control, fire and life safety, lighting systems, energy management, security access control, alarm and security devices, medical safety equipment, power metering, and more. These services have traditionally been provided as independent, standalone systems by multiple, proprietary vendors.
Today’s microprocessor-based systems offer tremendous benefits in terms of precise control and data gathering capability, but these benefits present challenges too. The greatest challenge presented by such a selection of affordable and impressive devices is that of integration.
Limbach Building Automation is in a position to support multi-vendor products in an effort to provide best-of-breed solutions for our customers. We are working with vendors that provide systems designed around standard protocols. Device communications standards such as BACnet, LonWorks, ModBus, Apup, and Java are becoming widely accepted in the B.A.S. community and are, for the first time, permitting seamless interoperability between new B.A.S. services from multiple vendors.
Protocols in the control system integration, open protocol and standard protocol, are terms often used to discuss two very different methods of achieving interoperability.
- Open protocol means that the communications language, which is typically proprietary, used to exchange information between microprocessor-based devices, is published and openly available. This makes it possible to develop an interface or gateway to products supporting that protocol. The difficulty with gateways is that they represent bottlenecks that can adversely affect the ability of systems to share data.
- Standard protocols, on the other hand, refer to communications methodology that is developed through a public and cooperative process, resulting in a non-proprietary language that all manufactures have agreed to equally. Standard protocols allow products developed by different manufacturers to communicate without the need for a gateway, which can lead to true interoperability.
The primary goals of Limbach Company B.A.S. are to provide solutions to several key issues that continue to plague the control systems industry. These include:
- Successful integration of multi-vendor building automation products.
- Seamless integration of B.A.S. data with enterprise information systems.
- Ready and secure access to multi-site, multi-user, and multi-platform control systems that take advantage of cost effective, internet-based user interfaces anywhere in a global organization.
- A comprehensive, object-oriented solution that supports rapid application development. One that integrates the entire software development process from planning and analysis, through design, construction, and maintenance.
Limbach Building Automation approach to automation technology embraces many industry standards to achieve openness and integration. We have developed a unique approach and implementation that provides a multi-vendor, interoperable control system that satisfies the need for internet openness, while maintaining the determinism and integrity required for real-time control, recognizing the value of open technologies that allow interoperability of multi-vendor equipment and compatibility of control and information management applications.
The benefits of true openness are extensive, but the single most valuable result is that it puts the customer in control of their facilities, letting them choose the products they want, with the features they need, from the vendors who perform to their expectations.
Limbach Building Automation provides a link to manufacturers and products that have developed and implemented standard protocols into the products they have developed.
