Communication paths of BACnet client
The PN/BACnet LINK reads the values of the corresponding "Present_Value" properties and
transfers them to the S7 controller via references to input objects. The PN/BACnet LINK
writes values which come from the S7 controller to the associated "Present_Value"
properties of the corresponding objects via references to output objects.
The "Status_Flags" are transferred to the S7 controller as input data. With "Status_Flags",
transmission is always from the object to which the reference is pointing, to the S7 controller,
independent of the type of object.
