Benefit from a readily available Modbus protocol stack...

... and save development time. FieldTalk^™ is easy to integrate into your application. The API is user-friendly and straightforward.

Trusted by thousands of commercial users

FieldTalk has a long track record with proven reliability. FieldTalk is used by large automation companies like Siemens, Schneider and ABB and even NASA. With the included commercial support provided by experienced software and communication engineers and included 12-month software maintenance, your project is on the path to successful completion.

Product ready

The licensing scheme is designed for commercial OEM users. No GPL or 3rd party license issues. We offer a no-nonsense per-developer-seat - no-royalty license.

Engineered for Control and Supervisory Systems

Typical applications are SCADA systems, Modbus data concentrators, user interfaces, factory information systems and industrial IoT gateways.

During the course of implementation, the usability in automation, control and other industrial environments was always kept in mind. The result is a well performing and robust Modbus library.

The Architecture

The FieldTalk architecture is based on a programming language neutral but object oriented design model. This design approach enables us to offer the Modbus protocol stacks for C#, VB.net, Java, Object Pascal and for C++ while maintaining similar functionality.

The C++ editions of the Modbus protocol stack have also been designed to support multiple operating system and compiler platforms, including real-time operating systems. In order to support this multi-platform approach, the C++ Modbus editions are built around a lightweight OS abstraction layer.
