Check driver communication error file

Block type (data table type) does not match object type.

In case of communication problems, the driver writes a detailed problem analysis into the driver communication error file. This file is stored in the project directory (RT\\FILES\\zenOn\\custom\\log). The name of the file is _<drivername>.TXT.
The file can be opened with any text editor, e.g. Notepad.

For additional error analyses, please send a project backup and the "error file" to the support team responsible for you.
