DCS control system and development trends
FCS, the help of field bus technology, all the I, / O modules are on the industrial field, and all of the signals through distributed intelligent I / O modules in the field is converted into a standard digital signal,[link widoczny dla zalogowanych], only one cable can be all the on-site sub-station link, and then the scene is very simple to send signals to the control room monitoring equipment, reducing costs, and easy to install and maintain,[link widoczny dla zalogowanych], while the system has a high data transmission speed and a strong anti- interference. (2) FCS is open. In FCS, the software and hardware are subject to the same standards, interchangeability, and replacement easy. Programming with five international standards IECIBI-3 programming language, programming and development tools are completely open, while the rich can take advantage of PC hardware and software resources. (3) the system efficiency greatly improved. In the FCS in a PC can simultaneously use both the original equipment to complete the PLC and NC / CNC tasks. WindowsNT multi-task operating system, PC in the soft PLC can run up to a dozen PLC task,[link widoczny dla zalogowanych], not only improves the efficiency and reducing costs. The PLC and PC with online debugging and emulation capabilities, greatly improving the programming per · environment. 4 Concluding remarks can be seen from the preceding discussion, FCS key technology of smart meter technology and field bus technology. Smart meters not only has high accuracy,[link widoczny dla zalogowanych], can be self-diagnosis, etc., but also has control, will replace the traditional 4-20mA analog gauges. Connecting field bus intelligent instruments site is an open, digital, bidirectional transmission of multiple contacts serial data path, it is computer technology, automatic control technology and communication technology product of the combination. Pc rich combination of hardware and software resources, both to overcome the shortcomings of traditional control systems,[link widoczny dla zalogowanych], but also greatly improve the flexibility and efficiency of the control system, the formation of a new control system, creating a new era of automatic control, automatic control of a inevitable trend of development.
