A distributed control system (DCS) is a computerized control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers ...
Centum, Yokogawa's flagship DCS, has the largest capacity among DCSs, supporting up to 1 million device tags. Yokogawa manufactures field instruments, test and measurement instruments, and semi-conductor related products. Yokogawa designs and manufactures the most advanced confocal spinning disks used in confocal microscopy. [12] [13]
A dispatcher training simulator (DTS), also known as an operator training simulator (OTS), is a computer-based training system for operators (known as dispatchers) of electrical power grids.
In 1975, Honeywell and Yokogawa introduced the world's first DCSs, the TDC 2000 and the CENTUM system, respectively. [ 18 ] [ 19 ] These DCSs were the next step in allowing flexible process control throughout a plant, with the added benefit of backup redundancies by distributing control across the entire system, eliminating a singular point of ...
Profibus PA (process automation) is used for communication between measuring and process instruments, actuators and process control system or PLC/DCS in process engineering. Profibus PA is a Profibus version with physical layer suitable for process automation, in which several segments (PA segments) with field instruments can be connected to ...
Process controls (basic as well as advanced) are implemented within the process control system, which may mean a distributed control system (DCS), programmable logic controller (PLC), and/or a supervisory control computer. DCSs and PLCs are typically industrially hardened and fault-tolerant.
OPC servers provide a method for different software packages (as long as it is an OPC client) to access data from a process control device, such as a programmable logic controller (PLC) or distributed control system (DCS). Traditionally, any time a package needed access to data from a device, a custom interface or driver had to be written.
