Yokogawa Electric Corp. has developed what it says is an enhanced version of its flagship integrated production control system. Set for release in February 2015, the CENTUM VP R6.01 is crucial for the company's VigilantPlant strategy for the IA business, Yokogawa stated.

The adaptive evolution of the CENTUM VP focuses on addressing customers' needs to keep up with the fast pace of change in the business landscape and technology while delivering maximum return on assets and the lowest total cost of ownership.

This first R6-level release of the CENTUM VP system represents much more than conventional functional improvements, the company indicated. R6 brings together smart engineering, advanced operation, system agility and sustainable plant. With R6, plant operators can be assured of an optimum engineering environment that spans the entire plant lifecycle, from plant design and the engineering and installation of systems and devices to the start-up of production, maintenance and renovation. In addition, it is geared to meet the most stringent industry requirements for safe and reliable plant operations and environmental protection, noted Yokogawa.

R6.01 expands the company's line-up of I/O devices and introduces essential control system components. Combined with an intuitive engineering environment, it dramatically reduces the time required to configure and install a control system, stated the company.

The N-IO, or Network-IO, is a field I/O device with a versatile I/O module that can handle multiple types of I/O signals. Control systems rely on field I/O devices for the transfer of data to and from sensors, valves and other types of field instruments. Using this data, they automatically control a plant's operations. Depending on instrument models, the type of electric signal used to transfer this data varies. With Yokogawa's FIO device, a compatible I/O module is needed for each signal type.


The N-IO, a CENTUM VP FIO device, fulfils the functions of universal I/O and a signal conditioner, enabling configurable software and flexible I/O assignment. It has an I/O module that accommodates multiple I/O signal types, accepts up to 16 I/O points, and allows specification of an individual signal type for each point. Both analogue and digital I/O signals, which account for the majority of I/O signal traffic, can be handled solely through software settings. Pulse and relay I/O signals can be managed by using additional adaptors. With the N-IO, it is no longer necessary to replace the I/O module, reducing the amount of rewiring that must be done when changing sensor types and/or layouts during a plant revamp. This significantly reduces the amount of work that has to be performed by plant engineers and maintenance personnel.

In addition, Yokogawa has signed OEM agreements with Pepperl+Fuchs GmbH and MTL Instruments Group Ltd, under which Yokogawa will receive baseplates and market them as its own products. These will be used in combination with the company's N-IO modules and intrinsic safety (IS) isolators procured from the two companies. Both partners have solid track records in the development of interface products for use in hazardous areas. This tie-up means Yokogawa is able to ensure that the N-IO conforms to the major IS regulations in Europe, Asia and the Americas.
