A short guide on how to use BACnet Configurator to add BACnet support to a CODESYS project.
If I understand correctly this is all about using the controllers as BACnet devices. My needs are simple. I need to read and write to existing BACNet devices which are not WAGO controllers. The configuration sees them in the scan. How to I add those to my controller to use in the logic? I see I can add a BACnet node.
Please use the same document linked above and see the Advanced Usage: Client Mappings section starting on page 10. You first create BACnet objects in the WAGO controller, and then use the Client Mapping feature to link those objects to objects on other devices in the network.
You can use FbRemoteObject and FbRemoteProperty in WagoSysBACnet -library for that purpose. The use of these function blocks is described in the library documentation.
