blockDewpointMonitoring
Extends from Interfaces.Partial.PartialFunction (Superclass for all function blocks to provide graphics and enforce implementation of functionality).
Information
Overview
Block that implements function "Dewpoint monitoring" from VDI 3813 [1, section 6.1.4, p. 12-13].
Functional Description
"The sensor function Dewpoint monitoring (RA-FL section 2, column 3; informative function block Figure 5) provides information on the risk of dew formation at the measuring site in terms of the states “dewpoint reached” or “dewpoint not reached”." [1, section 6.1.4, p. 12-13]
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 dewpoint limit is reached B is true and B_DEW is set to true. If dewpoint limit is not reached B is false and B_DEW is set to false.
If PAR_CAL is set to false the logic is complementary/inverted. If dewpoint limit is reached B is false and B_DEW is set to true etc..
