YOKOGAWA CENTUM VP System FCS (Field Control Station)

Sequence control: mainly based on ST16 (sequence table) and LC64 (logic diagram), adapted to interlocking and start stop processes;

Batch control: Implement batch operations for the entire unit through unit instrument blocks (U-TSW, OPSBL).

Question 3: How does the hardware composition and communication capability of CENTUM VP FCS support distributed deployment and multi device integration?

answer

Distributed deployment support:

Hierarchical design of node units: Local nodes (ESB bus) are connected to FCUs nearby, while remote nodes (ER bus) can be deployed near field devices, with distance extended through optical relays or wireless communication;

Optical ESB bus extension: FFCS-V supports optical ESB bus, with a maximum transmission distance of 50km in chain/star topology, suitable for large-scale factory deployment;

Compact installation feature: Can be installed in IEC Zone 2/Class I Div.2 hazardous areas, reducing cable routing costs.

Multi device integration capability:

Fieldbus support: compatible with digital fieldbuses such as FOUNDATION fieldbus (ALF111 module), PROFIBUS-DPV1 (ALP111 module), etc;

Subsystem communication: Supports 9 types of communication protocols such as Modbus, MELSEC, PLC-5, etc., and is compatible with Mitsubishi, Rockwell and other brands of PLCs, frequency converters, analyzers and other equipment;

Open interface: Vnet/IP bus supports third-party Ethernet devices, reducing integration costs;

Communication redundancy: Subsystem communication supports dual redundancy configuration to ensure reliable data transmission.
