The ‘Alarm Status’ register (register 6) is available as a read_only reg
-
ister for the ‘Process slave’ mode and as a read/write register for
the ‘Full slave’ and ‘Text’ modes. This register contains the status of
alarms 1, 2 and 3. Status is active or inactive.
The ‘Alarm Status’ register is 1 character (1 byte) register, with pos
-
sible values from ‘0’ to ‘7’. The alarm status for each value are indi
-
cated at
Note that the ‘Alarm Status’ register contains a value that is the ASCII
code of a number from ‘0’ to ‘7’. The reason is to maintain the pro
-
tocol structure of transmitting ASCII protocols. Note that the value
represented by this character is the binary code representing the sta
-
tus of the alarms. for example, ASCII code 53 represents number ‘5’,
which in binary is ‘0101’, and corresponds with alarm status 3, 2 and
1 in ‘on’, ‘off’ and ‘on’.
