This paper deals with the design of a communication layer between the components of a smart factory or other system.Each member of the Internet of Things has its own control system based on microprocessor.All IoT components have to work with programmable analog and digital inputs and outputs and other buses and have to communicate, exchange information and cooperate with each other.The control units are equipped with wifi modules and it is necessary to design program structures for communication.Control units must be able to solve combination and sequential problems based on automata.Closed graphs of control unit automats are interconnected by means of wifi messages.The structure of these messages is designed, which must contain component addresses and transmitted information of various types, character, string, numeric variables and arrays.A general library of functions containing typical elements of automata was designed.This general library has been implemented on two specific production systems and home automation tasks.
