I am looking for methods, examples, information on APIs used for data transfer of tags. What is there available to get me started with an application like this?

    Hello,

    When you say "transfer of tags", I assume you mean transfer of data to and from variables (tags?) that you have defined in a PLCnext Engineer project? If not, please correct me. Otherwise ...

    If you would like to use a REST API with JSON to read and write variable data rather than, say, OPC UA - the best place to start is probably the PLCnext Technology Info Centre, where you will find the specification of the REST API.

    There is also a sample application on our Github page, which might help.

    If you get stuck, there has been some discussions in this forum about the REST API, so a search might answer any questions you have. Otherwise, please let us know if you have any other questions.

    ~ Martin.
