1 foreword because reason of compatibility of standard of industrial spot bus line, be in a lot of building in industrial control project, industrial aether net with its low cost, fast substantial results, tall expansibility makes technology of industrial pilot mainstream. The net of SIMATICNET industry aether of research and development of company of German Xi Menzi regards Ximen Ziquan as one of compositive automation system main component, it is labour accuses domain application system of comprehensive industrial aether network. The different communication system that SIMATICNET provided those who accord with ISO/OSI network to consult be opened below the model to apply to all sorts of control level below industrial environment, the communication that controls a system for perfect industrial automation provides component and network system. SIMATICNET of overview of net of aether of 2 SIMATICNET industry is an open, efficient industrial newsletter network system. Basically comprise by 3 parts: INet of NdustrialEthernet industry aether; Profibus spot bus line; A-SInterface front bus line. Pass above combination of system of 3 parts network, SIMATICNET can apply at all industrial automation domains almost, the whole system that implements the appearance that disperses the spot, controller, computer is compositive. SIMATICNET industry is reached with using screen double skeining thread fiber-optic transmit as communication medium. Network develop attacks the structure has bus line model, annulus wait for a structure. Network join component has OSM (pattern plate of optical switching equipment) with ESM (pattern plate of electric switching equipment) treat series switching equipment. Establishing the facility with aether the most crucial net among them is the communication processor of CP series. It is OK to pass user of CP series pattern plate very convenient have S7 series PLC link through aether net, and support uses STEP7 software. The OPCServer that can go up with PC at the same time has communication. Software of network of SIMATICNET industry aether includes SIMATICNETV6.

0 with OPC (OLEforProcessControl) standard, among them SIMATICNET software provided unified Windows picture, offerred APC through it (AdvancedPCConfiguration) advanced PC configures a tool, a site that the PC can regard whole system as to control a system has communication with other PLC station, SIMATICNETOPC is a server / the client carries a structure, the client carries the program that visits a server. The each other that used OPC technology to rise to control a system greatly operates gender and adaptability. Network of system of control of engine of Lian Zhu of the 3rd steelworks configures 3 aid steel automation of base of engine of Lian Zhu of base of 3 refine armor plate controls aid steel the fundamental industry that the system uses the apparatus that the SIMATICNET technology compose of German SIEMENS company builds to accuse syncretic namely controls a network. Whole basis automation controls systematic cent to be 2 class, one class is by computer of system of expert of end of client of L1 server, L1, intelligence (ASTC, MoldExpert) with each advocate network of aether of PLC composition industry, what network communication medium uses is screen double skeining thread and fiber-optic, communication rate is 10Mb/s, use annular develop to attack structure, have the trade of information, it is OK to make operate personnel equipment of spot of real time monitoring runs state, undertake be controllinged remotely on HMI according to producing a situation, the formal record that can carry equipment travel circumstance adopts curve or written language comes down, with research and development of equipment later period. The 2nd class is to satisfy each data answers a demand quickly between PLC and each monomer equipment, the Profibus network in using SIMATICNET communication system loses a network as it is said as unit progression, PLC of the main body that finish and long-range I/O system, distributinging I/O system and transducer communication, follow a demand in order to satisfy manufacturing fine. PLC basically uses S7-300, S7-400 and C7 series to make give priority to a station, the intelligent unit such as long-range I/O, transducer serves as from the station, advocate station and have news report through PROFIBUS_DP of spot bus line from the station. In this control system all electric equipment include PLC, number to introduce product of German SIEMENS company gearing entirely. The layout of whole network is shown 1 times like the graph. Graph Nextpage of configuration of network of system of control of the 1 engine that connect casting connects casting machine to control a system to operate server of a station, computer and long-range I/O composition by 4 18 PLC, computers by this. Among them 4 advocate PLC includes PLC-C, PLC-S, PLC-I, PLC-R to be hanged on industrial aether net directly, the others PLC and intelligent equipment are passed Profibus-DP and respective advocate PLC corresponds. PLC-C uses at public system detect and control, PLC-S detects with what shed a system at casting and control, PLC-I detects with what express a system at appearance and control. PLC-R uses at roller road system detect and control, each PLC has the others to a PLC detects with what move wide system at crystallizer and be controlled, a PLC uses at crystallizer vibration system detect and control, 2 are used at crystallizer fluid of the system detect and control 3 to be used at hydraulic pressure system detect and control, 2 slip with Yu Run of the system detect and control, 2 are used at, of machine of 2 blaze cut detect and control, with Yu Zhu base makes date machine 1 detect and control, 1 is used at the machine of burr detects and be controlled. Installed 4 computers to operate a station to be used at intelligent man-machine interface, put in respectively advocate operation room and room of operation giving base, have dynamic surveillance and operation to joining casting machine, print call the police incident. Core equipment server places Yu Wei in unit room. The tool of PLC process designing that 3 steel-making control even casting machine the system uses 4 systems software and steel of data communication aid the Step7 of Siemens company.

0 software, this software may pass aether net to undertake long-range configuration to S7 series PLC, process designing and diagnose. Digit is occupied on collect, surveillance and control picture system namely SCADA (SupervisoryControIAndDataAcquiSitionSystem) , develop the UGS company Factorylink7 that software uses.

5, this software is the software that is based on Server/Client mode, a Server can figure the system with a 100 Client huge composition on join, can undertake the long-range configuration in the network, configuration is convenient, the function is powerful. Factorylink7.

5 this software use OPC technology and SIMATICNETOPC server communication, carry spot signal join according to uniform standard and server, realize dynamic data switch, the data flow of whole system is shown 2 times like the graph. Graph flow of 2 systems data pursues through going up 4 clients that we can see a system carry the computer to have communication with L1 server directly, read from inside the server take field data, and the OPC server of the OPC client end that L1 server regards SIMATIC 　 as NET and SIMATICNET corresponds, the OPC server of SIMATICNET ability is direct with what issue a PLC to have news report, those who realize pair of PLC memory unit is direct undertake reading writing a visit, achieve thereby will control casting machine to produce a course through PLC. System of control of network of automation of machine of 3 steel-making Lian Zhu used steel of 5 last word aid the advanced technique of automation, especially SIMATIC 　 NET and the application that are OPC technology, make the system is safeguarded not only, still facilitate patulous, the system is cast with taste quality to raising high yield up to now, improvement operates a condition, raised labor efficiency to have positive effect.
