Frequently Asked Questions?

The name “SIGNET” is derived from two critical words in the field of communications – “SIGnals” + “NETworks”.

SIGnals are ‘a detectable physical impulse (such as a voltage, current, or magnetic field strength) by which messages or information can be transmitted’. NETworks are ‘a system of computers and peripherals that are able to communicate with each other’. Together SIGnals and NETworks form the basic building blocks of an Open Automation System and hence are critical for building infrastructure and interoperability.

An Open Automation System refers to a type of automation technology that is designed to be interoperable and compatible with various components and devices from different manufacturers. In contrast to proprietary automation systems, where all components are sourced from a single vendor, an open system allows for the integration of diverse hardware and software elements from multiple vendors.

The concept of openness allows greater flexibility, scalability, and customization in building automation and control solutions. It promotes seamless communication between different devices and software, facilitating data exchange and interoperability, ultimately leading to more efficient and cost-effective automation solutions.

Open Automation Systems are often utilized in the built environment, including commercial buildings, industrial facilities, and smart homes, where various systems like HVAC, lighting, security, and energy management need to work together harmoniously to achieve optimal performance and energy efficiency. The openness of these systems enables easy upgrades, expansion, and integration with emerging technologies, making them future-proof and adaptable to changing needs and technological advancements

A building automation system (BAS), also known as a building management system (BMS) or building control system (BCS), is a sophisticated network of components and technologies designed to automate and control various systems within a building. The components of a building automation system can vary depending on the complexity and specific requirements of the building, but some common components include:

Sensors: These devices monitor various parameters within the building, such as temperature, humidity, occupancy, CO2 levels, lighting levels, and water flow.
Actuators: Actuators control various systems and equipment in response to the data received from sensors. They can operate HVAC dampers, valves, lighting fixtures, and other building equipment.
Controllers: Controllers process the data from sensors and make decisions based on programmed logic or algorithms. They determine the appropriate actions for the actuators to optimize building performance.
Building Management Software: The software serves as the brain of the building automation system, allowing operators and facility managers to monitor and control building systems from a central location.
Human-Machine Interface (HMI): The HMI provides a graphical interface for building operators to interact with the automation system and access data, alarms, and control features.
Energy Management System (EMS): The EMS optimizes energy consumption by coordinating and controlling the operation of HVAC, lighting, and other energy-consuming systems based on occupancy and schedule.
Supervisory Control and Data Acquisition (SCADA): SCADA systems provide real-time monitoring and control of various building systems and collect data for analysis and optimization.
Networking and Communication Protocols: Building automation systems use various communication protocols (e.g., BACnet, LonWorks, Modbus) to enable data exchange and interoperability between different components.
Building Analytics and Data Logging: Analytics software collects and analyzes data from various sensors and systems to identify trends, anomalies, and opportunities for energy savings and operational improvements.
Security and Access Control Integration: Integration with security and access control systems allows building automation to manage access, monitor security, and respond to security-related events.
Fire and Life Safety Systems Integration: Building automation systems can interface with fire alarm and life safety systems to initiate appropriate responses in case of emergencies.
Power Supplies and Backup Systems: Reliable power supplies and backup systems are essential to ensure continuous operation of the building automation system.
Energy Metering and Monitoring: Energy metering and monitoring equipment track and measure energy consumption to identify areas for improvement and implement energy-saving strategies.
Remote Access and Mobile Apps: Building operators and managers can access and control the automation system remotely through mobile apps or web-based interfaces.

The integration and coordination of these components allow building automation systems to optimize energy usage, improve occupant comfort, enhance building performance, and streamline facility management and maintenance.

ASHRAE, founded in 1894, is a global society advancing human well-being through sustainable technology for the built environment. The Society and its members focus on building systems, energy efficiency, indoor air quality, refrigeration and sustainability within the industry. Through research, standards writing, publishing and continuing education, ASHRAE shapes tomorrow’s built environment today. ASHRAE was formed as the American Society of Heating, Refrigerating and Air-Conditioning Engineers by the merger in 1959 of American Society of Heating and Air-Conditioning Engineers (ASHAE) founded in 1894 and The American Society of Refrigerating Engineers (ASRE) founded in 1904.

BACnet, the ASHRAE building automation and control networking protocol, has been designed specifically to meet the communication needs of building automation and control systems for applications such as heating, ventilating, and air-conditioning control; fire and other life safety and security systems; energy management; lighting control; physical access control; and elevator monitoring systems.

The BACnet protocol provides mechanisms by which computerized equipment of arbitrary function may exchange information, regardless of the particular building service it performs. As a result, the BACnet protocol may be used by mobile and cloud-hosted devices, head-end computers, general-purpose direct digital controllers, and application-specific or unitary controllers with equal effect.

This protocol provides a comprehensive set of messages for conveying encoded building automation data between devices including, but not limited to

(a) hardware binary input and output values,
(b) hardware analog input and output values,
(c) software data values,
(d) schedule information,
(e) alarm and event information,
(f) trend and event logs,
(g) files,
(h) control logic,
(i) application specific data for a large range of building services, and
(j) network configuration including security.
