blockPresenceDetection
Extends from Interfaces.Partial.PartialFunction (Superclass for all function blocks to provide graphics and enforce implementation of functionality).
Information
Overview
Block that implements the functionality of "Presence detection" from VDI 3813 [1, section 6.1.2, p. 10-11].
Functional Description
"The sensor function Presence detection (RA-FL section 2, column 1, see Section 7.3, Bild 61; informative function block Figure 3) automatically detects the presence of persons in the room and passes the output information of either the “present” or the “absent” state to those application functions whose response is determined by the room occupancy state. Due to the use in connection with lighting functions, the output information must be generated without any delay when the status of the evaluation unit changes." [1, section 6.1.2, p. 10-11]
