Whenever a physical connection according to Figure 1 or Figure 2 is made, the digital interface enables the
transfer of product recognition data to the transport tank. The purpose of this digital interface is to provide the data
of the following types of applications:
a) automatic product identification for each compartment or tank;
b) cross over prevention.

5 Design characteristics
5.1 General
The PRD shall be located on the transport tank. The PID shall be connected in series to a current loop with the
PRD.
The PRD reads the PID by powering the PID through the hose or loading arm. The PID then sends its data by
modulating the supply current, which is sensed by the PRD, see Figure 3.
The PID sends its data, using messages, which are numbered from 1 to 255.
The PID always transmits "message #1". By implementing more messages, it is possible to program the PID with
other types of information, see 6.6.
Since the PID modulates the supply current, PID's shall not be connected in parallel.

Start bit
The SYNC-block shall be followed by one Start bit of logic 0.
Block Length
The first Byte sent shall be a single Byte (unsigned) specifying the number of Bytes to follow, i.e. the number of
Bytes within the Data Block plus 1 for the checksum Byte.
Data Block
The Data Block shall hold the application data. It may contain more than one message.
If a Data Block contains more than one message, the messages shall be sent in ascending order of message
numbers. That means message #1 first, followed by e.g. message #2, message #5, . message #n.
Checksum
The checksum shall be the least significant Byte of the arithmetic unsigned binary sum of previously sent Bytes of
the telegram starting with the Block Length Byte.
6.5 Message format

6.6 Message specification
6.6.1 Reserved messages
The message identifiers from 1 to 32 are reserved for the purposes of this standard.
