FFVO142: Product OverviewThe FFVO142 is a Foundation Fieldbus H1 interface module within ABB’s S800 I/O family, designed to provide a complete Fieldbus solution for process automation systems. This module serves as the interface between the controller (such as an AC 800M) and field devices on a Foundation Fieldbus H1 network. Installed in an S800 I/O station, it functions as a Link Master, managing the data exchange and schedule on the fieldbus segment. It connects to the controller via a high-speed serial link (12 Mbps) and provides the necessary power conditioning and signal conversion for the H1 fieldbus (31.25 kbit/s).The module operates as an active interface, providing power and communication on the fieldbus segment. It includes advanced power conditioning to ensure signal integrity and supports bus-powered field devices. The module manages the Link Active Scheduler (LAS) functionality, which is critical for deterministic communication on the fieldbus. It also provides isolation and protection for the control system from the fieldbus network.FFVO142: Technical Specifications

Core Features & Customer ValueThe module’s integrated power conditioning is a critical feature that ensures stable communication by providing a clean power source for the fieldbus segment and isolating the communication signal from electrical noise. For system engineers, this eliminates the need for an external fieldbus power conditioner, simplifying design and reducing component count. The Link Master capability allows the module to act as the LAS, managing the deterministic schedule for time-critical data and providing redundancy support.The module’s robust design makes it suitable for use in harsh environments, including hazardous areas with the appropriate certifications. For maintenance teams, the module provides diagnostic information about the health of the fieldbus segment and connected devices, aiding in troubleshooting and reducing downtime. The integration with System 800xA provides a unified engineering environment for configuration, monitoring, and asset management of the entire fieldbus network.Typical ApplicationsIn process industries like oil and gas, chemical, and pharmaceutical plants, the FFVO142 is used to interface with a wide range of fieldbus devices such as smart pressure transmitters, temperature transmitters, level transmitters, and valve positioners. It enables advanced diagnostics and remote configuration of these devices.In large tank farms, the module connects to level gauges and temperature sensors on storage tanks, providing centralized monitoring and control while reducing wiring costs through the fieldbus network.
