Frequently Asked Questions

How Does Yokogawa Prevent Single Points of Failure to Ensure High System Reliability?

Yokogawa systems incorporate redundancy at multiple levels, including redundant controllers, networks (e.g., Vnet/IP), and power supplies. The distributed database architecture means that the process data resides in the controllers (FCSs), so the failure of an operator station or even the master engineering station does not affect the system’s ability to control the plant.

What is VNET/IP, and why is It Important in the Yokogawa Distributed Control Systems?

Vnet/IP is Yokogawa’s proprietary, high-speed control network, compliant with the IEEE 802.3 Ethernet standard. It ensures fast and reliable data exchange between all CENTUM components and field devices, forming the backbone of the control system communication.

Can Third-party Systems Be Integrated With the Yokogawa DCS?

The Yokogawa Distributed Control System allows integration with third-party systems using industry-standard communication protocols, such as Modbus TCP/RTU, Profibus, and Ethernet/IP.

What Are the Security Measures Offered by the Yokogawa DCS?

To protect against unauthorized access and cyber threats, the security features offered by the Yokogawa DCS include

• network segmentation,
• access control lists (ACLs),
• data encryption,
• robust user authentication mechanisms,
• logging capabilities to track system activities.
