Industria1 “five features of DCS system: 1、 The comprehensive control system integrates DCS & PLC & field bus; 2、 RISC superscalar high-speed CPU with super performance; 3. High reliability, strict industrial application practice, and application performance of…
MS_ Wi ndows2000 has been widely used in various fields all over the world and has become the de facto standard computer platform Set. The operating station 0s, engineer station es and data gateway GS of the industrial “system have adopted this platform, thus ensuring the It is universal, open and easy to use, and…
management level, not only the traditional control system monitoring operation function is realized Can (operate and display, print, trend display and alarm), and also complete system hardware diagnosis and data exchange between different systems Yes. The process control level realizes various loop adjustments including complex control (various PID, ratio, Simith, etc.) and high-speed logic control…
system monitoring operation function is realized function (operation and display, printing, trend display and alarm), and also complete system hardware diagnosis and data exchange between different systems. can. The process control stage realizes various loop adjustments including complex control (various PID, ratio, Simith, etc.) and high-speed logic control. Control, sequence control and batch intermittent control…
equipment (PROFIBUS, FOUNDATION Fieldbus, HART, etc.) and device parameter settings. ● Automatic generation of global data between the process control station and the operator station According to communication. For field devices, process control stations and operator stations, a unified global database is used for the entire control system, thereby reducing cost and time investment in…
Glossary Process station: This term is used to describe AC800F controllers (field controllers) and rack-mounted controllers. A process station can be designed to be redundant configuration and non-redundant configuration. AC800F : This term is used to describe the AC800F Field Controller type of process station. A redundant process station consists of 2 AC800F controller. Rack…
options. Each PS allows to insert 4 fieldbus interface cards (the card type can be different), Each card is connected to 1 field bus to collect process data and diagnostic information from the bus, the interface card is easy to replace and plug and play (Plug & Play), and can be plugged and unplugged. The…
field bus instruments. Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus. Simple layout, due to the use of…
The configuration language is based on the IE061131 3 industry standard, providing function block diagram (FBD), ladder diagram (LD), instruction list (IL), sequential function chart (SFC), structured text (ST) and other graphical configuration methods. The system contains about 220 functions Algorithm library for energy blocks and a basic library with more than 200 graphic symbols…
