Characteristic Yokogawa DCS :
(1) Distributed control system DCS and distributed control system TDCS are monitoring technologies that integrate 4C (Communication, Computer, Control, CRT) technology.
(2) A top-to-bottom tree-like topology large system, where Communication is the key.
(3) PID is in the interrupt station, which is connected to the computer and field instruments and control devices.
(4) It is a tree topology and a parallel and continuous link structure. There are also a large number of cables from the relay station to the field instruments in parallel.
(5) Analog signal, A/D-D/A, mixed with microprocessor.
(6) One instrument is connected to I/O with a pair of wires, and the control station is connected to the local area network LAN.
(7) DCS is a three-level structure of control (engineer station), operation (operator station), and field instrumentation (field measurement and control station).
(8) Used for large-scale continuous process control, such as petrochemicals.
