Note: Please note that a technical limitation of
the driver connections cannot necessarily be achieved by a single driver. Depending on
the load and dimensioning of the system, number of data transfers, etc., it is
recommended to divide the driver connections among several driver instances or
distributed systems in order to reduce the individual load of a driver.
