Editing Very Simple Control Protocol (section)

==Event==
VSCP is based on ''events''. Each time an ''event'' occurs it is broadcast towards all other nodes. Each node on the network will receive the event and will decide if this event needs to be handled or not.

The example given in the diagram describes a button being pressed. This will result in node 1 sending an event message onto the bus informing all others the button is pressed. Node 2 receives the message but decides this button should not trigger an event for node 2. Node 3 receives the message and decides this button should trigger lamp 2 to turn on.

There can be ''events'' for all sorts of things happening: an event can be a button pressed, a presence sensor being triggered, or the sun setting. Events can also be sent periodically, for instance a temperature reading every minute. VSCP predefines many events that could be happening. These events are defined into classes and types. Whether or not an event received should be handled is determined by the ''decision matrix'' or DM in short. Also the DM is explained further.
