Gas reading (by status)
R
f32
2
Gas reading value calculated by device status (i.g
negative value in fault status )
1. If device is in Inhibit state, return value is base
concentrate of sensor data (In case of ECC,
Noramlly 0)
2. If device is in fault state, return value is :
3. return = f32_gas_full_scale / 16 * (fault current
value of configuration - 4.0);
4. If device is in warning state, return value is : return
= f32_gas_full_scale / 16 * (warning current value
of configuration - 4.0);
same as '30035 to 30036'
