Function and Positioning

The FC280SAV functions as the “field control backbone” of the I/A Series DCS, positioned as a distributed, fault-tolerant core for process automation. It independently or redundantly executes closed-loop control, logic operations, sequential control, data acquisition, alarm management, and network communication. It supports standalone operation without host workstations and enables online firmware upgrades without process downtime. Its patented fault-tolerant design supports 1+1 hot standby redundancy with seamless failover, ensuring uninterrupted operation in critical processes. As a central controller, it connects downward to 100/200 series FBM fieldbus modules and upward to the control network, enabling cross-level data exchange and control command distribution.
