You can refer to the documentation over at Snap7. This package is based off the last version of Sharp7 1.1.0.0 The version of this package will start with a base version off 1.1.0.0 and increment as fixes are made.
I intend to make this package thread safe and mvvm friendly.
To try and keep the implementation the same as the original Sharp7 package I have moved code into partial classes and kept the namespaces the same. As I go along I will add the xml documentation to the code so that it is easier to understand and use.
-
Fully standard "safe managed" C# code without any dependencies.
-
Virtually every hardware with an Ethernet adapter able to run a .NET Core 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.
-
Compatible with Universal Windows Platform including Win10 IoT for Raspberry.
-
One single file.This library has all the classes and structs seperated. -
Made thread safe.
-
Many function and methods now have async impementations.
PM> Install-Package SclSharp7
or
> dotnet add package SclSharp7
- S7 300/400/WinAC CPU (fully supported)
- S7 1200/1500 CPU
- CP (Communication processor - 343/443/IE)
An external equipment can access to S71200/1500 CPU using the S7 'base' protocol, only working as an HMI, i.e. only basic data transfer are allowed.
All other PG operations (control/directory/etc..) must follow the extended protocol, not implemented yet.
Particularly to access a DB in S71500 some additional setting plc-side are needed.
-
Only global DBs can be accessed.
-
The optimized block access must be turned off.
- The access level must be “full” and the “connection mechanism” must allow GET/PUT.
