Initializing FBoxes
Capturing analog values
The project requires 2 COBs with a total of
9 Fupla pages.
Right-clicking on the COB opens the
Properties window opposite. Here there are
instructions with which new pages are
created (“Insert Page”) or a name assigned
(“Properties”).
Initialization
If the user wishes to use FBoxes from the
HVAC library, he must place an HVAC
initialization FBox at the start of the Fupla
file.
Various common properties of the HVAC
FBoxes, such as the behavior of the FBox
after loading or the start-up behavior when
switching on the PCD, are set with this
initialization FBox.
Capturing analog values
The temperature values for outside, supply
and exhaust air and the return flow are to
be captured. To do this, the Conversion
FBox from the HVAC General FBox family is
placed on the page four times, then the
Filter T1 FBox from the HVAC Filters FBox
family placed next to each one.
The FBoxes and Connector must be
connected.
Assign the FBoxes a name. (Right click on
FBox – Properties
Name).
Create symbols in the Symbol Editor and
move them to Connector using drag-and-
drop.
