Introduction

The newly developed TwinCAT library Tc3_BACnetRev14 implements a fully object-oriented engineering and configuration process to provide a convenient project planning of Beckhoff BACnet controllers.

Using the library does not require any OOP (Object-Oriented Programming) skills. However, for advanced users, this architecture offers flexible extendable options.

So far, using the older library Tc2_BACnetRev12, the connection between the PLC variables and the BACnet supplement was established using the automapping process. The BACnet function blocks were complemented by comments describing the object properties which were parsed by the map or remap function in the System Manager. This process is still available in TwinCAT 4024 and can be used by adding the library Tc2_BacnetRev12. Please note that this function may no longer be supported in future TwinCAT versions!

Using both libraries Tc3_BACnetRev14 and Tc2_BACnetRev12 within one project is not supported.
