Key Words: DELTA Fieldbus Ethernet Devicenet PLC HMI 1.

Foreword Devicenet is current of relatively popular spot bus line among them a kind. Since of system of control of spot bus line opens communication network, it is system of a kind of full distributinging control. It joins the intelligent equipment that regards a network as node into automation network system, computation of implementation foundation control, compensation, parameter is revised, call the police, show, monitoring, optimized integrated automation function. It is the integrated technology that with intelligent sensor, control, computer, number communication, network is main content one. System of spot bus line broke a tradition to control what the system uses to press control loop demand, the undertakes connecting a line respectively configuration with man-to-man equipment. Put module of output of the control module that control room is in formerly in DCS system, each input into spot equipment, add spot equipment to have communication capacity, consequently control system function can not depend on the computer in control room or control appearance, finish in the spot directly, realized complete dispersive control. System of spot bus line has the following characteristic on the technology: · system has open sex and each other to use the level with same comply with of sexual communication agreement, information exchange can come true between equipment, the user can press his need, the product composition different supplier opens interrelating system. Between the system, can undertake information is exchanged between equipment, the device with the similar performance of different production manufacturer is OK crossing-over. System of sex of autonomy of · system function will be passed feeling measure, the function such as processing of amount of compensation computation, project and control is dispersive finish in spot equipment, spot equipment can fulfil the basic function of automata, can diagnose the moving condition of equipment at any time. · system has what bus line of dispersive sex spot forms is a kind of completely dispersive control construction of system, simplified construction of system, raised dependability. The adaptability spot bus line that · system has pair of environments supports line of double skeining thread, coaxial cable, cable, radio frequency, infrared ray, power to wait, have stronger interference rejection capacity, can use two lines to make implementation power supply and communication, can satisfy the requirement of safe explosion proof. Because structure of spot bus line simplifies, the functional unit such as segregation of the signal recuperation that needs DCS system no longer, changeover reachs its complex wiring, saved hardware amount and investment. The simple design that connect a line, saved installation cost. Equipment is had diagnose oneself handle ability with simple breakdown, decreased to safeguard workload. The interchangeability of equipment, intelligence is changed, the accuracy that digitlization improved a system and dependability. Still have a design simple, reframe easily wait for an advantage. Computer network, communication develops with what control a technology, bring about the deep reform of automation system. IT is permeating the equipment layer that produces the spot quickly, enclothe what manage to business management from manufacturing workshop each respects, communicate supply from raw material, production makes production attemper, each link of resource program and even market sale, form the business information system that is a foundation with controlling a network stage by stage. Spot bus line (Fieldbus) the new technology that complies with development of this one trend to rise namely. And the trend that the system of intranet sth resembling a net that is a foundation with spot bus line is current business development more. If plan institute shows,be: It is sketch map of system of intranet sth resembling a net with spot bus line. Nextpage2.

Manufactory of PLC of project setting brief introduction is the manufacturing section that produces a stage to amount to the series PLC such as DVP-S and DVP-E, the item that makes this is 3 among them produce a line to include: ICT condition, ASSY condition, T2+PACK condition, among them every information condition that produces a line to include 8 kinds to reach above for example: Short yield a line calls the police, money of 2 O/I mistake, lot, test is treated undesirable etc. Through spot sensor (thermocouple) , carry out implement (electromotor) the feedback information that reachs operation personnel, in control room engineer can see clearly produce a line to move condition and to produce a line to release manufacturing order to wait. So through what form will finish the information between the spot and control room, office and operator to exchange? This is the problem that we pay close attention to most. Say generally, what this project uses is spot bus line (Devicenet) the communication kind that reachs industrial aether net will finish whole system information to exchange. This also was accorded with above the application that the computer network that elaborate plants in actual production, the profit that its bring no longer tired narrate. 3.
