Fieldbus Technology

Invensys offers a truly open automation system that interoperates with multiple device types, from multiple vendors, with multiple protocols, most commonly found in process plants.

The Foxboro® line of control and I/O devices provide seamless integration of fieldbus capabilities, including Fieldbus Foundation, Fieldbus Foundation Control in the Field, HART, PROFIBUS, DeviceNet, Modbus, and our own FoxCom, among others. Invensys is also a leading contributor to the emerging Field Device Tool (FDT) technology and is proud to be a founding member of the FDT Joint Interest Group.

As fieldbus technology continues to grow and expand, Invensys interoperability and anybus strategy will continue to meet the varying needs of the diverse process automation market. This philosophy allows multiple fieldbus communications while accommodating the user’s choice of instrumentation without restrictions on device types or suppliers. Whether new or existing installations, with I/A Series interoperability and anybus capabilities, users can maintain their preferences because the system adapts to the user.

Proven Foxboro I/A Series® remote fieldbus and field mounted FBMs have demonstrated significant wiring savings, up to 70%, compared to conventional methods. Ethernet connect I/O can be placed in the control center, close to the control processors and workstations, or out in the field, close to the process measurement and control devices. The I/A Series system has the capacity to handle multiple I/O types at that remote drop, including traditional I/O and intelligent FF, DeviceNet, HART, PROFIBUS DP and PA, FoxCom.
