Welcome to the Sharp7 wiki!

Sharp7 is the C# port of Snap7 Client. It’s not a wrapper, i.e. you don’t have an interface code that loads snap7.dll (or .so) but it’s a pure C# implementation of the S7Protocol.

It’s designed to work with small hardware .NET-based or even for large projects which don’t needs of extended control functions.

Main features

• Fully standard “safe managed” C# code without any dependencies.
• Virtually every hardware with an Ethernet adapter able to run a dotnet standard 2.0 can be connected to an S7 PLC.
• Packed protocol headers to improve performances.
• Helper class to access to all S7 types without worrying about Little-Big endian conversion.
• Built against .Net 4.0 and dotnet stardard 2.0
