blockPrecipitationDetection
Extends from Interfaces.Partial.PartialFunction (Superclass for all function blocks to provide graphics and enforce implementation of functionality).
Information
Overview
Block that implements function "Precipitation detection" from VDI 3813 [1, section 6.1.9, p. 17].
Functional Description
"The sensor function Precipitation detection (RA-FL section 2, column 8; informative function block Figure 10) provides information on rain, snow or other forms of precipitation. This information is used, e. g., as input information for protection functions of the sunshade or for the closing of window casements." [1, section 6.1.9, p. 17]
The calibration parameter PAR_CAL is used to choose the right contact logic.
By default PAR_CAL ist true which leads to a positive logic. That means if precipitation is detected R is true and R_ACT is set to true. If no precipitation is detected R is false and R_ACT is set to false.
If PAR_CAL is set to false the logic is complementary/inverted. If precipitation is detected R is false and R_ACT is set to true etc..
