CODESYS Communication

Using OPC UA Information Models

These are supported generically. The contents of the information model are translated into the corresponding IEC data types and declarations.

Using the IEC Symbol Set Configuration of the Communication Manager

IEC symbols can be released quickly and easily without having to explicitly create an information model beforehand.

You can use your own information models for OPC UA.

Method calls with information models are possible.

You can define completely independent symbol sets.

In the previous symbol configuration, it is possible to hide global variables depending on the symbol set, but the type configuration always has to be identical.

Additional abstraction between application and information model

In the Communication Manager, the names for the clients can be configured separately which allows for a clean separation.

In contrast, in the previous symbol configuration, the IEC names of the symbols are also transported outwardly, which means that refactoring in the application can result in clients having to be adapted.

Simplified rights management for the symbol sets

For more information, see: IEC Symbol Publishing

Better workflow: The IEC symbol publication editor provides the precompile information of the application for configuration. This means that the variables and types available in the project are provided for the configuration of the symbols in the editor without the application having to be compiled without errors. Discrepancies between the editor and the project, which may result due to changes in the project, will be brought to your attention and you will be assisted in making corrections.

Detailed output of the tag count for symbol sets

The user can better understand which symbols are effectively released.

User-friendly editors, for example filter options to improve clarity
