SIMATIC S7 COM 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) starting at byte twenty (20) and provided decoded as a double value. For programming, any language with support for Microsoft's COM technology such as C++, VB6 and VBA (in e.g. Excel or Access) can be used. The interfaces themselves only differ in terms of the programming language used.

Undecided?

Your application is a .NET application? The SDK is also available for C#, VB.NET and C++/CLI: SIMATIC S7 .NET SDK

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

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.

Licensing

Once purchased, a licence is valid indefinitely (= unlimited licence lifetime) and allows the development of any number of products as well as their unlimited distribution without further licence costs (= royalty-free). Included are 12 months Top Level Support by our developers as well as updates including new functions.

Shortly before the support expires, it is possible to extend it for at least another 12 months for 15% of the current list price. Updates and new functions can only be obtained with valid support. Support requests can still be submitted, but will be processed on a priority basis depending on their scope. Up to one month before the expiry of active support, we will notify you of the possibility of support renewal. Support renewal is possible at any time in the first year after expiry of support for 30%, in the second year for 60% and in the third year for 80% of the current list price. From the fourth year onwards, a new licence must be purchased for the support renewal.

Branch License

A Branch License applies to all developers who use the product for software development exclusively at the location (= a postal address at which development takes place) according to the licence agreement.

Single Developer License

A Single Developer Licence applies to a single developer who, according to the licence agreement, is the only one (= full contact details of the developer and employer) to use the product for software development.
