A3.12 System set-up mapping
System data will be available with read-write access in blocks of holding registers.
This data can be read with function code 03 and written with function codes 06
and 16.
0 = disabled, 1 = remote cal, 2 = auto val.
A3.13 Transducer set-up mapping
Each transducer will provide read-write access to various set-up data in blocks of
holding registers that can be read with function code 03 and written with function
codes 06 and 16.
Each register provides 2 bytes of data so it takes 2 registers each to store a 4 byte
floating point measurement value.
A block of 100 registers is allocated for each transducer to provide the means of
supplying the transducer related set-up data as follows:
