Integer Registers
The integer data type could be used for the Results data and configuration/control parameters.
The “holding registers” as referred to by the Modbus specification, are read/write registers. This
16-bit integer data type can be manipulated using functions 3, 6, and 16.
Function 3 allows the host to read one or more holding registers per query.
Function 6 allows the host to write a single holding register per query.
Function 16 allows the host to write multiple holding registers per query.
Result Data Functions
The result data functions available via Modbus are listed below. The registers are accessed using
Modbus function 3. If variable type is not specified, the default variable type is a 16 bit unsigned
integer.
