Sensor function to retrieve window state from physical sensor

## Information

#### Overview

Block that implements function "Window monitoring" from VDI 3813 [1, section 6.1.3, p. 11-12].

#### Functional Description

"The sensor function Window monitoring (RA-FL section 2, column 2; informative function block Figure 4) provides information on the open/closed state of, e. g., a window casement, a sash, a group of casements, etc., in terms of the binary states “open ” or “closed ”." [1, section 6.1.3, p. 11-12]

The calibration parameter PAR_CAL is used to choose the right contact logic.

By default PAR_CAL ist true which leads to a negative logic. That means if the window is closed B is true and B_WINDOW is set to true. If the window is open B is false and B_WINDOW is set to false.

If PAR_CAL is set to false the logic is complementary/inverted. If the window is closed B is false and B_WINDOW is set to true etc..
