14.5 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
14.5.1 Analogue Registers (Integer)
Channel Analogue Value (Integer)
01 30001
02 30002
...
64 30064
Note: The Integer format is a 16 bit signed integer, range -10000 to +10000 in steps of 0.1 %FSD
14.5.2 Analogue Registers (Float)
Channel Analogue Value (Float)
Register 1
01 30129
02 30131
...
64 30255
Note: The Float format is a 32 bit floating point value in accordance with IEEE 754-2008
14.5.3 Animation Registers
A group of animation values are allocated for registers 30065 to 30128. These are intended to be used by
graphics packages for defining the colours of various screen objects based upon the status of a channel.
A 16 bit unsigned word format is used.
