Tab. 6-6: Identification data
Node ID
All BML sensor heads with the DRIVE-CLiQ interface have
a unique
Node Identifier
. This ID is generated from certain
parameters and from the sequential numbers of the serial
numbers of the sensor head and used during DRIVE-CLiQ
communication to identify the device.

Tab. 6-7: Node ID
Encoder serial number
The encoder serial number is another parameter that can
be used to identify the BML sensor heads via the DRIVE-
CLiQ interface. This ID can be read by the sensor head
and is generated from part of the node ID and from the
identification serial number of the sensor head.
The generated
encoder serial number
has the following
format:

Tab. 6-8: Format of the DRIVE-CLiQ serial number
Data format: YYYYMMDD
– YYYY is the year
– MM is the month
– DD is the day
The serial number consists of the following two main
elements:
– Device type and sub-type of the node ID
– Sequential serial number
