11.2 Modbus Register Allocation for Function 04 – Read Input Registers
There are three sets of input registers for each channel:
1. The analogue signal expressed as a 16 bit signed integer value.
2. The analogue signal expressed as a 32 bit floating point value.
3. An animation value.
11.2.1 Analogue Registers (Integer)
This register contains the indicated measured value in steps of 0.1 measurement units (e.g. PPM, LEL). This register should
not be used on channels where the parameter "Gas Range Max" is set to values greater than 1000.
Table 23. Modbus Channel Analogue Values
Note: The Integer format is a 16 bit signed integer.
11.2.2 Analogue Registers (Float)
Table 24. Modbus Channel Analogue Values (Float)
Note: The Float format is a 32 bit floating point value in accordance with IEEE 754-2008.
