What is the logical device name?
The logical_device_name is used for a world-wide unique identification of each logical device.
It is an octet-string up to 16 octets. The first three octets uniquely identify the manufacturer of the device. It is assigned by the DLMS UA in co-operation with the FLAG Association. The manufacturer is responsible for guaranteeing the uniqueness of the octets that follow (up to 13 octets). The logical device name is held by the SAP assignment object or a COSEM logical device name object - a data or register object with the logical name 0.0.42.0.0.255. When short name referencing is used, the base_name of the COSEM logical device name object is 0xFD00.
