Oh sorry I mixed up the name. The correct name is CSV_WRITER_x and you can find it in the utils directory. Where x is the number of inputs that should be written into a comma separated values file. The file would then be located on your controller.
Monitoring is definitely not suitable for real-time data and was never intended to be used for that.
If you need your real-time data remotely for analytics. This is what several other users of 4diac intend to do then I would recommend to also have a look on our MQTT and OPC UA support.
Cheers,
Alois

Hi,
thanks for the clarification. You know that this feature will require, depending on the size of your application quite some memory and will have quite some performance impact?
We are open source and the Eclipse Public License allows to modify and extend the source we are providing. You can even distribute the changes. However you should be aware if you are modifying code that we are providing you need to make these changes available again. At least this is my understanding of the Eclipse Public License. You may want to check your self and consult lawyers to be on the save side.
Maybe a further comment on doing such changes: I would try to do them in such a way that you can easily update to newer 4diac FORTE versions. Therefore maybe funcbloc.cpp is not the best place for your changes. With 4diac 1.10.0 Jose introduced a feature which allows to easily replace the default CEventChainExectutionThread class. As this is the class sending events to a FB it would be a good place for doing something what you intend and at the same time have minimal changes to FORTE. An example of a different CEventChainExecutionThread implementation can be found in FMU.
I hope this helps and answers you questions,
Alois
