Modbus address * 256 + 2. For example an
N N XNX at Modbus address 010 will appear as
2562 or 0x0A02.
C N analog_value (2)
C N normal (0)
"SSS GGGG AdAAA.AlarmA" where SSS is
the sensor type, GGGG is the gas name and
AAA is the Modbus address. Values for gas
name include "CO" and "COMB". Gas
N N names are truncated to 4 characters.
Values for sensor type are "XNX" or "XCD"
For example, an XNX at address 10 with a
Methane sensor will populate this object
name with "XNX

"SSS GGGG AdAAA.AlarmB" where SSS is
the sensor type, GGGG is the gas name and
AAA is the Modbus address. Gas names
are truncated to 4 characters. Values for
N N
sensor type are "XNX" or "XCD" For
example, an XCD at address 11 with an H2S
sensor will populate this object name with
"XCD H2S Ad011.AlarmB"
