CODESYS has its own IIoT Library, which includes libraries for communication and libraries for reading and writing of common data structures for IIoT. The current AX-3 already supports the license; however, to program the project, the user needs to import the library from the CODESYS store page. Delta already pays the license fee for this library and puts it into the AX-3 controller; customers don’t need to pay anything for the IIoT license.
Go to CODESYS store page: Link, you may need to register an account to download the library.
Click the version below and select 1.11.0.0, the latest version compatible with AX-3 FW version 1.0.8.1.
Double-click the download package file, and it will start the installation process.
Once the installation is done, you may create a project on DIADesigner-AX and add the IIoT library to the project. (Here use JSON lib as an example)
