Modbus Complete:

Modbus Master Driver No other Modbus protocol stack offers the variety of platforms, physical layers, protocol variants, programming languages, and functionality of FieldTalk.

Benefit from a readily available protocol stack...

... and save development time. FieldTalk is easy to integrate into your application. The API is user-friendly and straight forward.

Your Design-in investment is secure

The library distribution contains source code and documentation as well as 12 month update guarantee.

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 royalties license.

Master and Slave Stacks

We offer both, master and slave protocol stacks.

Engineered for Control and Supervisory Systems

Typical applications are supervisory control systems, data concentrators and gateways, user interfaces and factory information systems. The Java edition helps publishing plant floor data on the web using Java applets and Java servlets. 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 library.

The Architecture

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

The C++ editions of the 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++ editions are built around a lightweight OS abstraction layer.
