Manipulator is now use d as a i ndustrial robots i n use, the contr ol objective s often a ppear often in i ndustrial aut omation. In dustrial a utomation technology has gradually matured, a s mature a technology li ne ha s bee n rapi d devel opme nt in i ndustrial aut omation a s a separate subject. Mani pulat or appli cation bega n to filter into wel ding, logisti cs, me cha nical processi ng, a nd ot her industries. Espe cially at hig h or very low temperatures, f ull of poisonous gase s, hig h radiation ca se, robot in similar cir cumstances showed great use also bri ngs great conve nience to t he staff. Precisely beca use of this robot to get people's attenti on began to be a hig h degre e of devel opme nt. La bor rates, w orking conditions, la bor i ntensive aspects of promoti ng devel opme nt. Both at home and abr oad to devel op the PLC (programmable l ogic contr oller) is in vari ous spe cial circumsta nce s and under spe cial conditions set for mecha nical devices. Now t urne d on t he dev elopment of the micr oele ctroni cs a utomatic control technology a nd the rapid devel opment of the trains, t he success of PLC hardware software a nd simulation control wi n big a nd successful devel opme nt, now conti nues t o devel op a s a factory aut omation sta ndar ds. Because robots are good development of the technol ogy makes a good optimization of pr oductive capital, a nd robot s hows thi s uni que advantage s, such a s: ha s good compati bility, wide avail abilit y, har dware is compl ete, and programming t hat can be mastered i n a short time, so in the context of industrial PLC a ppli cations became ubiquitous. Mani pulator i n many developed country agriculture a nd i ndustry has bee n applied, such as t he use of mechani cal harve sting large areas of farmland, repeated operations on the high-speed l ine that use s a robotic arm, a nd so on. Today, the high level of automation combine d with restri ctions on the ma nipulator deve lopme nt level is slig htly lower t han the internati ona l. The desig n is mainly arm wel ding machine by PLC Aut omation control.

Now original r oboti c arm spent most of mass production a nd use on the production line, w hich is programmed robotic arm. A s the first generation of mani pulator position control systems mai n features, althoug h not back several generati ons t hat can detect t he external envir onment, but can still successf ully complete like wel ding , painti ng, delivery as well a s for materials simple mov ements.

m anipulat or control mode a nd programmable contr ollers intr oducti on 2.1 Select discussion with ma nipulator control 2.1.1 classification of control relay s and discrete ele ctroni c cir cuit can contr ol ol d industrial e qui pment, but al so more com mon. Mai nly these two relatively chea p and you ca n meet the old -fashi one d, sim ple (or simpl e) industrial e qui pment. So he ca n se e them now, however these two contr ol mode s (relay and discrete electr oni c circuits) are the se fatal flaws: (1) cannot ada pt to the com plex logic control, (2) only for t he current pr oje ct, the la ck of compatibility and (3) not reforming the system with qui pment impr ovements. Spring for t he devel opme nt of Chi na's m oder n industrial a utomation technology the substantial i ncrea se in t he level of industrial aut omation, com pleted the perfect relay of the computer t oo much. In terms of contr olling the com puter show d his tw o great advantage s: (1) each of the har dware ca n be installe d on one or more mi croproce ssors; (2) the official desig ner of the software writing content control i s all about. Now in several way s in the context of industrial a utomation ca n often be see n in t hree ways: (1) Pr ogrammable Logical Contr oller (referred to as IPC); (2) Distributed Contr ol System (DCS for short), and (3) the Pr ogrammable Logica l Controller (PLC for short). 2.1.2 PLC a nd the IPC and DCS contrast contrast 1, each of the t hree technologie s of origi ns and dev elopment requirements for fast data processi ng makes it invented the computer. The me n br ought i n terms of har dware there , usi ng a hig h level of sta ndardization, ca n use more compati bility tools, is a ri ch software resource s, especi ally the need for immedia cy in operati onal sy stems. So t he computer can effectively contr ol is used t o control a nd meet its spee d, on the virt ual model, real -time and in computational re quireme nts.
