21 IdentificationType

The IdentificationType represents general information about a machine. The information is fixed by the manufacturer and not changeable by the user. It is used instead of the MachineInformationType where the detailed information of the MachineInformationType is not needed e.g. in a horizonal communication between machines in a production line.
