7.4.1 BMS Master
A Master can query all warning and operating messages from a Slave.
If the bus address 1 has been selected for one IRDH375B, this device automat-
ically represents the Master, that means that all addresses between 1 and 150
are cyclically scanned via the BMS bus for alarm and operating messages. If
the Master receives no answer from five subsequent addresses, the scanning
cycle is started again. If the Master recognizes incorrect answers from a Slave,
the fault message "Fault RS485" is issued by the Master.
