4.4.8 Reset
Write value 1 to this register to reset currently active trip,
if any.
4.4.9 System date
Read or update the system date. The date is stored in the
Arc Monitor so if updated it will take up to 2 seconds for
the change to reflect in the HMI.
The date is expressed as number of days since January 1,
1970.
Example: the value 0x42B6 (17078) corresponds to
October 4, 2016.
4.4.10 System time HHMM
Read or update the system time. The time is stored in the
Arc Monitor so if updated it will take up to 2 seconds for
the change to reflect in the HMI.
The time is expressed in 24h format as a 16 bit value where
the most significant byte contains the hours and the least
significant the minutes.
Example: the value 0x0922 (2338) corresponds to 09:34.
4.4.11 Modbus failure register
This register contains the PDU Address of the Modbus
register that was involved in the last Modbus exception.
Example: if one attempts to read System date and System
time HHMM (PDU addresses 1100, 1101) but accidently
specifies 3 registers instead of 2, one will get an Illegal
Data Address exception as response since also address
1102 will be queried. The Modbus failure register will
contain value 0x044E (1102).
