I want to implement modbus on devices, however I don't know the definition of discrete input, input register, holding register, coil.
Also, do i need to implement all those function to read/write these values?
MY own interpretation is that: 1) input: device hardware input, 2) Coil: Hardware Output 3) holding register: status of the device. Am I right?
