Industria1 “system communication Industrial ial “the system uses the international standard industrial bus. The field controller supports PROFIBUS, FF, MODBUS, can and other countries International standard fieldbus, PROFIBUS is…
library of energy block, the basic library with more than 200 graphic symbols and the extended library with a large number of 3D symbols. The system uses the same set of configuration tool software to complete the configuration and commissioning of process level, operation level and even fieldbus instruments, and uses the same A global…
control level is realized by the di ginets network (Industrial Ethernet /iee802.3 standard), The user can select the communication transmission medium (ordinary cable or optical fiber) and network topology structure according to the actual situation of the application. Popular PC and MS_ Wi ndows2000 has been widely used in various fields all over the world…
by ABB in technology Information technology) a new trend. The system is divided into two levels: operation management level and process control level. At the operation 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…
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 functions. The internal communication of the process control station (between the controller and various intelligent devices such as I/0 or field instruments) adopts the international standard field controller. Wire. The field…
of international field bus standards. It has both the complex analog loop regulation capability of DCS Power-friendly human-machine interface (HMI) and convenient engineering software, and at the same time have high-speed logic and sequence control equivalent to high-end PLC indicators. control performance. The system can be connected to both conventional I/0 and various field bus…
programmed by the user, a list of variables and labels is automatically created. Moreover, both variables and process points can be opened and closed directly in FBD or IL Revise.
