Read data from BACnet

In the Programming editor, right-click the input pin of a program block and select Read from BACnet and the BACnet object type you want to create.

A function block with program function is created and connected to the input pin.
A BACnet object is created and linked to the function block.

In the Programming editor, right-click the output pin of a program block and select Show on BACnet and the BACnet object type you want to create.

A function block with program function is created and connected to the output pin.
A BACnet object is created and linked to the function block.
