First of all is important to take into account that different names for Modbusfunction codes,
are used in technical literature depending on the manufacturer of the Modbus device. The
following table shows the equivalence between nomenclature for function codes, used by
Intesis Software in IntesisBox and the used in Modbus protocol specification.
Function code
IntesisBox Modbus protocol specification
01 Read digital outputs Read Coils
02 Read digital inputs Read Discrete Inputs
03 Read analog registers Read Holding Registers
04 Read analog inputs Read Input Registers
05 Write 1 digital output Write Single Coil
06 Write 1 analog register Write Single Register
15 Write multiple digital outputs Write Multiple Coils
16 Write multiple analog registers Write Multiple Registers
