Whether a particular device includes all of these register types is up to the manufacturer. It is very common to find all I/O mapped to holding registers only.
Coilsare 1-bit registers, are used to control discrete outputs, and may be read or written.
Discrete Inputsare 1-bit registers used as inputs, and may only be read.
Input registersare 16-bit registers used for input, and may only be read.
Holding registersare the most universal 16-bit register, may be read or written, and may be used for a variety of things including inputs, outputs, configuration
data, or any requirement for
“holding”
data.
11.7 Modbus summarized
Use a twisted pair cable (shielded, if possible)
Check the polarity of the wires (different names for different manufacturers: A, B, D+,
D-
…)
Always place at least 1 termination resistor (at the end(s) of the bus)
Don’
t leave the termination resistor(s) without polarization. Place the bias resistors only in 1 point of the bus:
Avoid stubs:
Double check the addressing of the registers (standard, absolute, offset base 1, offset base
0…)
