BACnet objects of the type "Binary input (BI) and "Analog input" (AI) are inputs on the
BACnet side. The values are written from the S7 side to the "Present_Value" property of the
corresponding input object.
BACnet objects of the type "Binary output (BO) and "Analog output" (AO) are outputs on the
BACnet side. The "Present_Value" properties of the output objects are read from the
S7 side.
With server objects, the PN/BACnet LINK writes the status information transferred by the
S7 controller to the property "Status_Flags" of the corresponding objects.
