Enhanced integrated production control system.

An enhanced version of Yokogawa's CENTUM® VP integrated production control system has been released. The enhancements in this latest release, R6.04, include a new input/output (IO) module that will give Yokogawa end users a greater range of choices.

Control systems rely on field IO devices to transfer data to and from field instruments such as sensors and valves in order to automate the control of plant facilities. CENTUM VP’s N-IO (Network-IO) is one such field IO device. As the universal IO module originally developed for the N-IO device can handle a wide variety of IO signal types, it is easy to install different types of sensors when constructing a new plant or renovating an existing facility; this saves significant time and effort, and makes it possible to complete such projects much sooner. There are cases, however, when users may wish to add sensors that do not require this versatile capability. For just such a need, Yokogawa has added to its N-IO lineup a new low-cost IO device that handles only digital signals.

Enhancements
1. New IO module
As the latest control systems often primarily use digital signals, a new, low-cost IO module that handles only digital signals has been added to the N-IO lineup. To accommodate both analog and digital signals, it can be used in combination with the universal IO module. In this way, the cost of a plant construction or expansion project can be reduced.
In addition, a signal conversion function is included in the new IO module’s adaptor. With the universal IO module, a dedicated signal conversion board is required to directly receive signals from a field instrument such as a temperature sensor. The incorporation of this function in the new IO module eliminates the need for this hardware.

2. Windows 10
This latest CENTUM version uses Microsoft Windows 10 Enterprise, the optimum OS for control systems. Based on its Long-Term Servicing Branch (LTSB) service model, Microsoft provides five years of extended support in addition to the standard five years of mainstream support (free-of-charge support that includes security patch updates), thus enabling a 10-year product lifecycle. By such means, Yokogawa continues to optimize its systems and, in turn, ensures stable long-term performance.

3. Ring network topology
CENTUM VP’s Vnet/IP® is a control network originally developed by Yokogawa and features high reliability and quick response. CENTUM VP’s Vnet/IP® real-time control bus uses the star topology, in which all devices are connected to a central hub. This latest CENTUM version also allows the use of a ring topology, in which devices are connected to each other in the form of a ring. With this feature, more flexible networks can be configured to satisfy customer needs.

Major Target Markets include process industries such as oil and natural gas, petrochemicals, chemicals, electric power, pulp and paper, pharmaceuticals, foods, iron and steel, and water and wastewater in the operation, monitoring, and automatic control of plants.
