Modbus is an application layer protocol in Open System Interconnection (OSI) layers. Modbus protocol specifies a communication standard for industrial applications and devices to communicate. In short, Modbus is all about a collection of function codes. According to Modbus specification (v1.1.b), each request and response is MODBUS is an application layer messaging protocol, positioned at level 7 of the OSI model, that provides client/server communication between devices connected on different types of buses or networks.

    Conforms to Modbus Application Protocol Specification V1.1. Supports any physical communication network including RS 232/485 (for RTU and ASCII), Modbus Plus, and TCP. Can be used in event-driven or non-event-driven environments. Supports binary data (coils and discrete inputs) and analog data (holding registers and input registers). Modbus is an application layer protocol in Open System Interconnection (OSI) layers. Modbus protocol specifies a communication standard for industrial applications and devices to communicate. In short, Modbus is all about a collection of function codes. According to Modbus specification (v1.1.b), each request and response is
