FluentModbus

FluentModbus is a .NET Standard library (2.0 and 2.1) that provides Modbus TCP/RTU server and client implementations for easy process data exchange. Both, the server and the client, implement class 0, class 1 and class 2 (partially) functions of the specification. Namely, these are:

Class 0:

• FC03: ReadHoldingRegisters
• FC16: WriteMultipleRegisters

Class 1:

• FC01: ReadCoils
• FC02: ReadDiscreteInputs
• FC04: ReadInputRegisters
• FC05: WriteSingleCoil
• FC06: WriteSingleRegister

Class 2:

• FC15: WriteMultipleCoils
• FC23: ReadWriteMultipleRegisters

Please see the introduction to get a more detailed description on how to use this library!
