A market-leading remote I/O system for Zone 1, Div. 1 applications, the IS1 (photo) has now been extended to feature its first operational communication interface for Foundation Fieldbus High Speed Ethernet (FF HSE). The system has already supported the Modbus TCP protocol for basic Ethernet performance. This new FF HSE version now provides users with a more advanced and considerably more powerful Industrial Ethernet protocol implementation. Remote I/O technology allows users to deploy consistent plant communication networks integrating conventional HART-capable and Foundation Fieldbus H1 devices. — R.
