MODBUS Register Numbering Convention
MODBUS data points consist of 4 main types: coils, status, input registers, and holding registers.
The numbering convention refers to the individual data points by prefixing their addresses so that
when looking at a number for a given point the user would know which type of data point was being referenced.
For example:
Coils do not have a prefix and so are referred to by their register number 1 through XXX.
Status registers are prefixed with 1X,XXX so they would fall in the range 10,001 through 1X,XXX.
Input registers are prefixed with 3X,XXX so they are in the range 30,001 to 3X,XXX.
Holding registers use a prefix of 4X,XXX so they are numbered between 40,001 and 4X,XXX.
These prefixes are automatically dropped in the actual low level messages and all data points are zero referenced.
When configuring master software to access these data points, care must be taken to address the registers
correctly, i.e. if the software used does not automatically remove the prefix, be certain only the register
portion of the address is used.
