Defines which Driver is used by this I/O Driver object to communicate with a device. This property accepts a String with the complete Driver's path, in case it is not in the same Domain's directory, or the relative Driver's path if it is in the same Domain's directory. In case there is no open Domain in Elipse E3 Studio, a relative path is considered as starting from the folder where the project or library containing this I/O Driver object is. After that, the DriverName property changes to the Driver's description. This property cannot be modified once communication starts. The default value of this property is an empty String.
