            Description

            Datatype CIP STRING encodes in the first UINT16 field the length of the string, i.e. the number of bytes it consists of. That means that an empty string, e.g. the device's default hostname "" should be { 0x00 0x00 } on the CIP protocol layer. Currently, it is initialized and delivered as { }.
