SIMATIC S7 .NET SDK

How to use

The SIMATIC S7 SDK enables the development of client applications for direct data exchange with SIMATIC S7 controllers and similar via TCP/IP. An Ethernet connection is required for communication. The IP address, slot and rack number of the CPU (if different from the standard) are sufficient to establish the connection. For development, no change to the controller, no additional PLC program, no licence from Siemens and no licence other than that for Traeger's SDK is required!

Access to the respective data area works with the usual SIEMENS and IEC syntax. In the above example, for example, a temperature value stored as a DWord is read from the data block with the number ten (10) from byte twenty (20) and provided decoded as a double value. Any .NET language such as C#, VB.NET and C++/CLI can be used for programming. The interfaces themselves only differ in terms of the programming language used.

Undecided?

Your application is not a .NET application? The SDK is also available for C/C++, VB and Delphi: IP-S7-LINK SDK

An application or a script in MatLab? The SDK is also available as a toolbox for MatLab: SIMATIC S7 MatLab Toolbox

A VB6 application, a VB script or a VBA macro in Excel, Access and Co? The SDK is also available as COM SDK for Microsoft's (D)COM technology: SIMATIC S7 COM SDK

Looking for a "ready-to-use" SIMATIC S7 client? In our Industry 4.0 middleware, SIMATIC S7 controllers can be easily addressed via OPC UA and REST API, their data stored in a database, forwarded to other devices, easily visualised and exchanged bidirectionally: Codabix Industrial Edge

In just a few steps, the middleware can be set up as a SIMATIC S7 OPC UA gateway. In this way, process data in data blocks, flags and inputs/outputs can be processed as required quickly and easily and data can be exchanged between them.
