Functional Block: Part of a switch that can be
considered as if it were an independent switch.

Examples:
1.   appliance with one functional block: the functional block is the switch, for example the actuator with 16 A 250 V~ change-over relay output (Eikon 26535, Idea 16975, Plana 14535).
2.   appliance with two functional blocks: in the interface for traditional switches (Eikon 20515, Idea 16955; Plana 14515) both inputs are functional blocks.
3.   appliance with three functional blocks; in the control appliance with two push buttons and actuator (Eikon 20526, Idea 16966, Plana 14526) there are three functional blocks; left-hand rocker push button, righ-hand rocker push button and actuator that, from the point of view of configuration and use, are to all intents and purposes 3 separate devices.

Set of functional blocks connected together that provide a function in the system (for example: three different buttons controlling a single actuator and as a result, the same load).
The devices forming a functional group are connected together logically and not according to conventional wiring.

The groups must comprise only homogeneous functional blocks: it is not possible for a group to contain an actuator for roller blinds and an actuator to control the switch on of a lamp.
To be able to control the switch on of a load from serveral points it is sufficient to add another button functional blocks to the group without having to change the wiring.

Group Depth: number of groups to which a functional block can belong. Each functional block can belong to at most 4 different groups.

Actuator Definition

An actuator is a mechanical device for moving or controlling a mechanism or system. The actuator is usually a physical mechanism but also refers to an artificial intelligent agent.
A device used to transfer motion from one object to another. An actuator activates a movement or a process.
The mechanism of a switch which operates the contacts.
A device to convert an electrical control signal to a physical action. Actuators may be used for a wide variety of operations (lights, dimmers, roller blinds, scene activations, access control).
A device used to transfer motion from one object to another. An actuator activates a movement or a process.
