1 Overview

Modbus.Net is an open source hardware communication framework. The framework itself does not implement any protocol, but provides a communication specification and unified calling interfaces, completely separating protocol implementations from user-facing APIs.

Modbus.Net is built on async/await, so neither protocol developers nor users need to deal with async implementation details — just use the reserved interfaces to communicate with many devices concurrently.

The design of Modbus.Net is inspired by the OSI model. Modbus.Net implements all layers in OSI except for the Physical Layer (hardware connections).

The goal of Modbus.Net is to allow different communication protocols to be implemented within the same specification, enabling users to communicate with various devices using a unified approach.
