4.4 Modbus Register Allocation for Function 02 – Read Input Status
This function reads the input channel status bits. Each status bit can have the value 1 = Active or 0 = Not active. For the
Channel Type only, 1 = Analogue or 0 = Digital. There are twelve status bits for each channel.

4.5 Modbus Register Allocation for Function 04 – Read Input Registers
There are three sets of input registers for each channel:
• The analogue signal expressed as a 16 bit signed integer value.
The analogue signal expressed as a 32 bit floating point value.
•
An animation value.
•
4.5.1

Analogue Registers (Integer)

Note: The Integer format is a 16 bit signed integer, range -10000 to +10000 in steps of 0.1 %FSD. e.g. if FSD is 500 and
the reading is 50, then the data will be 100 (10.0 %FSD).
