Yokogawa's Fieldbus Related Products


Applying Fieldbus in Plant Control System

CENTUM VP DCSThe engineering for fieldbus function blocks can be performed in the same way as for other function blocks in FCS. The operation and monitoring environment is also the same for the fieldbus function blocks and other FCS function blocks. No additional requirements for engineering, operation and monitoring of the fieldbus applications in Yokogawa DCS. The most favorable merit for applying fieldbus is highly efficient maintenance of field devices. Yokogawa offers an asset management software package, Plant Resource Manager (PRM), for device management and diagnosis. With PRM, the advantage of fieldbus can be optimized so as to make the maintenance of the whole system more efficient.

Plant Resource Manager (PRM)

CENTUM VP DCSThe maintenance information of devices are collected by PRM via fieldbuses and stored in the PRM database. The corresponding maintenance schedules, maintenance procedures and spare parts information are also stored accordingly in the same database. The maintenance of the field devices can be performed through fieldbus. Thus the maintenance engineers are considerably relieved from going to the fields of the devices in the remote areas and hazardous areas.

Audit Trail

Audit trail management is important in both control and maintenance systems. All maintenance works on devices, which are maintained by PRM, are recorded and stored, and can be easily retrieved too.

Predictive Maintenance

By integrated management of device management information, the replacement cycle of devices and trend of device troubles can be predicted. This technique minimizes the impact of device problems on plant operation, and maintenance work and parts procurement can also be planned and scheduled.

Solutions to Non-Fieldbus Devices

PRM can create a database for legacy devices in addition to Fieldbus devices. Maintenance information is recorded and managed in a database for integrated, overall planned maintenance of all devices in the plant.

System Software Updates

Periodically, system software must be brought up to date by adding new functions, enhancing existing functions, and fixing bugs. For a variety of reasons, many of our customers would prefer to wait for a scheduled plant shutdown to update their system software to the latest version. Even if a customer has not yet installed an earlier version of the software, Yokogawa guarantees that the system will keep working normally and without interruption when the latest software version is installed. Yokogawa also guarantees that the software will be fully compatible.

System Modification & Expansion

Our customers often need to modify or expand a control system after it is installed, and major concerns with this include avoiding disruptions to plant operations, minimizing the shutdown period, and minimizing the risks of a hot system cutover.

Yokogawa offers a virtual environment for FCS and HIS where both the control and operator functions of the CENTUM database can be tested without FCS hardware. It ensures the new programs will work when they are installed, reduces risks of system failures, and minimizes the shutdown period.

Upgrading (moving from one Yokogawa system to another Yokogawa system)

For each of its CENTUM systems, Yokogawa has paid particular attention to helping its customers manage lifecycle costs by optimizing the upgrade process. Upgrading is simple and quick.

All of Yokogawa's legacy CENTUM systems can be controlled and monitored from a newer CENTUM system. Via a control network, CENTUM VP can control and monitor operations at a plant that relies on a CENTUM V, CENTUM-XL, CENTUM CS, or CENTUM CS 3000 system. The latest CENTUM VP can also communicate with both the N-IO and the more traditional FIO and Yokogawa will continue to sell and provide long-term support to both types of I/O. Thus, by allowing its customers to utilize their existing assets wherever possible, Yokogawa offers them a cost-effective way to upgrade their production control systems.

Process manufacturers continue to demand more from their plants and automation systems. This demand is driven by business pressures for greater manufacturing flexibility and by customer pressure for faster, smaller deliveries and higher service levels. Manufacturers also realize that they need to improve the quality of their manufacturing operations for any number of reasons, most especially safety, as recent major accidents have shown. Abnormal operations, especially, present risks that these manufacturers need to reduce.


Asset health monitoring has long been in existence to protect expensive equipment and/or operations from costly, critical, or catastrophic failures, with numerous examples in nuclear, aeronautical, petrochemical, industries and beyond. The costs associated to install the sensors and asset health system way overcome the consequences of not implementing. However, this is not the case in all industries, with all equipment and/or all operations. In many cases equipment is run until failure and then repaired or replaced.
