YOKOGAWA FIO System (compatible with Vnet/IP) Hardware Specification Manual

Positioning and core use

The "FIO (Fieldnetwork I/O) System General Specification Manual" (document number: GS 33K50F10-50E) released by Yokogawa Electric Corporation is the 8th edition updated in September 2014. Its core purpose is to guide the module selection, system deployment, installation, debugging, and compliance verification of the system in the CENTUM VP (Vnet/IP) integrated production control system. The FIO system, as a field I/O solution, focuses on the acquisition and control of industrial field signals. It is interconnected with field control units (FCUs) through multiple buses and is suitable for process control needs in industries such as petrochemicals, power, and pharmaceuticals.

System architecture and core components

（1） Overall architecture design

The FIO system adopts a layered architecture of "FCU+node unit+bus", which realizes reliable interconnection between on-site signals and control units, supports dual redundancy configuration (power module, bus interface module, I/O module), and ensures high availability operation of industrial sites. The system can achieve chain or star topology expansion through the optical ESB bus relay unit (ANT10U), adapting to centralized and distributed deployment scenarios.

（2） Classification and specifications of core components

FCU is the system control core, responsible for receiving on-site signals from FIO node units and executing control logic. The specific model and characteristics are as follows:
