  • This slide represents the evolution of control systems in terms of technology and application. Electronic computers were first introduced in the field of process control in 1960’s. Digital control technology has developed widely over the last few decades. The introduction of computers was done initially for data logging and set point control. With the introduction of computers in to the process control, advanced controller functions were superseded by computers, and DDC (Direct Digital Control) in which computers directly controlled processes were deployed. In the early stages, the control system was centralized where a central computer executed not only monitoring and operation but also process control. The most important reason was cost effectiveness. The advent of microprocessors greatly changed the scenario. The research moved on to how diversification could be implemented to achieve risk distribution, function distribution. The Distributed Control System (DCS) incorporated all these functionalities and with DCS, the control function could be functionally as well as geographically distributed. However the monitoring was still centralized for easy plant operation and control. At Yokogawa it will be our endeavor to develop newer technology systems and integrate them with existing systems - the best technology with most accurate results.
  • Digital Control Systems have evolved with developments in technology. Yokogawa’s Process Control system development history has also followed the technological innovation ranging from simple single loop controllers to highly complex solutions involving DCS and advanced process control techniques.
  • World has seen a lot of technological evolutions in the field of Plant Instrumentation and Control Automation since 1970’s... Instead of single loops, larger and more complicated loops such as cascade, ratio, feed-forward, multi-variable were used for achieving better control. For optimum, safe, and reliable control, effective control loops were developed using regulatory control, sequence control and inter-locks with the aid of computers. Systematic and reliable startup/shutdown procedures were incorporated in the control logic to ensure the safety of the plant. Yokogawa were the pioneers in introducing the first Distributed Control System to the world. Centum was the first Distributed Control System introduced by Yokogawa in the year 1975. Yokogawa continued its research in the DCS field and introduced many systems in line with the technological development. CENTUM VP is the latest DCS introduced by Yokogawa. VP is Vigilant Plant . CS3000 systems uses Windows platform for the GUI functions. The primary factors considered during the development of CS3000 are Easy connectivity of components The abnormality of one component does not affect the functionality of others Easy creation of regulatory and sequence control loops using computers Operators can easily monitor and handle multiple plant data’s from a Centralised Control Room
  • Centum CS 3000 equipments : 1. Human interface station (HIS) Used for operation & monitoring Incorporates open interfaces - supervisory computers and workstations can access data, messages and process data. Engineering and test functions. Desktop and console type 2. Field control station (FCS) Standard and compact type Regulatory and sequential process control User programming functions Plant control and communication with PLC, DAS etc. 3. Bus convertor (BCV) To link V-net system bus to another CS3000 domain or existing Centum or  XL. 4. Communication gateway Unit (CGW) Links V-net to Ethernet bus. 5. RIO bus (twisted pair) Communication between remote I/O to FCS CPU. 6. Nodes Remote I/O units 7. V-net (Co-axial multidrop) - Links FCS, HIS, BCV, CGW 8. Ethernet (Coaxial) - Links HIS, ENG and supervisory system (Also for HIS data equalisation).
