Internal information
The row order can vary depending on the production year, only the longer row is
relevant. The back part of this and the shorter row contain internal administration
information from the manufacturer.
In addition, the serial number is printed on the front of the fieldbus
coupler/controller on the cover cap of the service interface, so that it can also be
read when installed.
