Machine Control
Bus-based Systems Bus-based machine control systems common today's industrial environment. STD, PC-AT only numerous options. Most these options operate through standard operating system (DOS, OS/2, OS/9) that used program add-on cards I/O, motion communication interfaces. Flexible graphical operator interfaces remain computer's major advantages. Some successful examples bus-based machine control applications include gear grinding dressing. placement machines, hard disk manufacturing, automotive glass bending. Wherever intensive communications data processing required, benefits structure realized. There some disadvantages bus-based machine control system that relate amount integration between motion structure. Separate cards required each, resulting need software integration different programming languages. Motion control operations, such servo loops, should polled updated more immediate basis than auxiliary operator interface. programmer must develop this polling hierarchy thread system together. Integrated controllers more integrated approach machine control uses stand-alone architecture that builds same essential elements I/O, motion, operator interface, communication. This approach uses single software hardware platform control entire machine application. polling servo loops, points, operator interface handled internally, invisible user. common software language provided integrate motion actuation. This pre-tested approach allows typical machine control application developed with minimum effort cost. total application cost major consideration when selecting integrated machine controller. While initial hardware cost typically higher than other solutions, software investment maintenance single language overriding positive factor. Software development maintenance costs machine control application dwarf initial hardware expense. integrated approach offers more economical solution.

Motion Control: precise programmable load movement using servo motor, stepper motor, hydraulic actuators. Feedback elements often employed. Analog Digital I/O: actuation external process, devices such solenoids, cutters, heaters, valves, etc. Operator Interface: flexible interaction with machine process both setup on-line variations. Touchscreens, data pads, thumbwheels examples. Communications Support: process monitoring, diagnostics data transfer with peripheral systems. There many different machine control architectures that integrate these elements. Each results varying levels complexity integration both motion non-motion elements. PLC-based, bus-based integrated solutions commercially available. Your selection machine control strategy will often based performance, total application cost, technology experience. PLC-based Control PLC-based architecture utilized intensive control applications. Based upon banks relays that scanned, polled, central processor, provides low-cost option those familiar with ladder logic programming language. Integration motion, I/O, operator interface, communication usually supported through additional cards that plugged backplane. addition scanning points decreases polling rate individual point, thus lead lower machine response. Because PLCs
Engineering Reference
Many industrial designers concerned with controlling entire process. Motion control important influential aspect complete machine control. primary elements machine control include:
have historically concentrated motion control, plug-in indexers those that communicate over preferable. Because these indexer boards often include their microprocessor, they prevent slow polling rates, incorporate separate programming language. general, this compromise acceptable most complicated motion/machine applications.
