What is LonWorks and how does it relate to DDC?

LonWorks is a simple sensor used for temperature measurement. LonWorks is a control networking platform for building automation enabling distributed control across devices. LonWorks is a cloud service for data analytics. LonWorks is a hardware standard for telecom.

Correct Answer:

LonWorks is a control networking platform for building automation enabling distributed control across devices.

Explanation:

LonWorks is a control networking platform for building automation that enables distributed control across devices. In a DDC setup, each device (sensors, controllers, actuators) runs control logic and communicates with others. LonWorks provides the network and standards to connect these nodes so control tasks can be performed locally and coordinated across the building, making distributed digital control possible and interoperable between different vendors. It is not a simple sensor, nor a cloud analytics service, nor a telecom hardware standard.
