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, PIDs shall not be connected in parallel. SIST EN 14116:2012

Both shall be able to read the messages. The current modulation by MultiPID shall result in a voltage modulation in PRD, due to its internal serial resistor. MultiPID shall be able to differentiate this from the modulation of the supply voltage performed by PRD. Therefore MultiPID shall measure the voltage changes caused by its own current modulation. PRD shall start its transmission not before the end of the start bit of the MultiPID and synchronously to the current modulation of MultiPID. MultiPID shall check the voltages synchronously to its own transmission and shall subtract the voltage change before its own check, i.e. it shall recognise the bits transmitted by the PRD. 5.9.3 Message timing The scan period shall be the repetition time until a scan line is powered up again by PRD.
