==Event Class and Type==
Events are organized into ''Classes''. A class is a collection of events that somehow belong together. There are classes for ''ALARM'', ''MEASUREMENTS'', ''CONTROL'', ''INFORMATION'', etc. Currently VSCP specifies about 25 classes, but has room for many more 1. Each class is on its turn subdivided into ''types''. A type further specifies the event within the class. For instance, events of Class ''20'' (0x14) are ''INFORMATION'' events. In this class there is a subtype ''1'' (0x01) ''BUTTON'' signaling a button being pressed. In this same INFORMATION class there are also types to signal ''ON'', ''OFF'', ''BELOW LIMIT'', etc. Likewise in class ''measurements'' there are types to signal temperature, current, voltage, etc. Having all these classes and types defined makes the nodes speak the same language. For a full list of pre-defines classes & types check the VSCP wiki.
