Read/Write Data points with driver

[wilko0070]

I wrote an external error handler in C++. With all types of managers (API, CTRL, UI, REDU, etc.) I had no problems to write the error messages to normal data points, but with drivers it is impossible for me to read from / write to data points. I always got the message "data point ... doesn't exist". Is there a solution to force the drivers to read data points outside their internal data point area?

The problem is possibly related to the fact that a driver does not load the complete DP identification and therefore the data point and element names are not known.
