R u16 1 MSB always 0x26 to facilitate automatic identification. LSB repeat of
Modbus address.
R u16 1 Identical to 40101
R f32 2 The reported gas concentration in current measurement units. For ex-
ample, methane at 50% LEL would be reported as 50.0 here.
This concentration is forced to last reading before switching into inhibit
mode during inhibit mode.
R u8 1 This is the integer representation of the fault status. If any fault exists this
will take a value in the range 1200 to 1999. Otherwise, if any warning
exists, this will take a value in the range 1 to 999. Normally, this has the
value zero.
