Field Bus Components

High efficiency paired with excellent usability are the core criteria for our STV fieldbus components. A web browser interface in the bus coupler enables simple system configuration and visualises the process. The components feature a transparent, easy-to-implement STV high-speed protocol. A Modbus TCP protocol may be used alternatively. Cycle times are individually configurable with automatic addressing of the individual modules. The system allows segments of up to 64 modules. We also implement dedicated, individual customer solutions.
