nd not expect to again opens. Reliability: Because PC has the magic hard disk and the non reliable part which revolves, like the power source, this makes it to be easier to appear the breakdown. Not familiar programming environment: The factory operator needs to have when maintains and fixes the breakdown restores the system the ability. The use trapezoidal logic, they may manual force the coil to restore to the perfect condition, and can fast patch the code which affects by is fast restored the system. However, the PC system needs the operator to study the new higher paraffin the tool. Although certain engineers use have the firm hardware and the specially operating system specialpurpose industry puter, but because Engineer PC reliable aspect question overwhelming majority avoids in the control using PC. In addition, uses in each kind of automated duty equipment in PC, like I/O, correspondence, or movement possible need different development environment. Therefore these must develop 20% application engineers either use PLC to be unable with ease to realize the function which the system needs, either uses both contains PLC and to contain PC the mix system, they use PLC to carry out the code control section, realizes the higher paraffin function with PC. Thus the present many factories workshops use the system which PLC and PC unifies, in use system PC carries on the data record, the connection bar code scanner, inserts the information in the database as well as issues the data to the on. Uses this way establishment system the main question is this system with difficulty constructs frequently, fixes the breakdown and the maintenance. System engineer must unify frequently es from many merchants software and hardware work to puzzle, this is because these equipment are not but design for can the joint operation. Constructs a better controller Because does not have suitable PC or the PLC solution, these need development plex application engineer on develops the new product with the control merchant close cooperation. They need the new product to be able to unify PC the senior software function and the PLC reliability. These important users were PLC and have provided the product development instruction based on the PC control pany. Realizes the software function not only to need to have the senior the software, moreover the controller hardware function also needs to have the enhancement. Because in the world scope is dropping to the PC part demand, therefore many semiconductors merchants start for the industrial application redesign their product. At present controls the domain the merchant to start in the industry control product to use the industrialization floating point processor, DRAM, solid state memory like Compact Flash as well as the fast Ether chip. This enables the merchant to use based on the PC control system flexibility and the usability develops a more formidable software, moreover this PC control system also may move the realtime operating system by to guarantee the reliability. This kind of new controller is the solution 20% the application question but designs, it unified PLC and the PC two merits. The ARC industry analyst is called this kind of equipment the programmable automated controller, namely PAC. The programmable logical controller world looks at in generally the research in ARC, they have produced the PAC five principal characteristics. These controller characteristics are through define the software the ability to realize its function. Multipurpose, has in the logic, the movement, the PID control, the actuation and processing in a platform at least two kind of above functions. Except that in order to realize special agreement like SERCOS to have to I/O makes some improvements。 Moreover the software also can provide logical, the movement, processing and the PID function. For example, the movement control took the software control circulation, it can reading the digital input from the orthogonal encoder, the execution simulation control circulates and outputs the control device the simulated signal. The sole multi regulations develop the platform use general label and the sole database visit all parameters and the function. Because PAC is like multipurpose but designs for more the senior application, they need the senior software. In order to can highly effective design the system, the software must be the sole integrated software package, but is not the many kinds of separations software tool, these software tools in the project cannot the seamless joint operation. Through unifies IEC611313, the user guide and the data management, the software tool can design is surmounting many machines and the processing unit processing flow. The simplification system design on the other hand is has the senior the development kit, uses this tool to be possible to cause engineer very with ease to transform the processing concept for can actual control the machine the code. The opening modular skeleton can solve the industrial application may distribute from the control in the factory machine to processes workshop the operation unit. Because all industrial application all needs to have highly has custommade the characteristic, therefore the hardware must be the modulation in order to engineers may choose the appropriate part. Moreover, the software also must be able to let engineer increase and the demolition module by the system which designs needs. Uses already the work interface standard which has, the language and so on, like TCPIP, OPCamp。 XML and SQL inquiry language. Can with enterprise39。 s work correspondence regarding the modernization control system be extremely essential. Although PAC contains has the ether connection, but in order to must does not have the equipment and the factory other systems the q。
