PLC (可编程逻辑控制器) In ordine moderatoris et microComputer moderatoris developed in ex moderatoris. Eius princeps reliability, simplex et intuitive via programming, et magis et magis perfectum functionem facit ea late applicantur in industria imperium agro. Among them, in a lot of automatic control system by PLC to control the step motor, when the PLC send pulse signals and direction, the stepper motor drive through PLC receives the pulse output pulse signal and the signal to control the stepper motor work direction, a pulse signal can make the stepper motor rotation Angle of a fixed, so there must be some relation between pulse number and frequency, frequency curve of step motor intuitive reflect this relationship. In progressionem automatic Chinese Traditional Medicine distribution system et progressionem de numero pulsus per plc potestate in conspectum motricium, curare medicina accipere medicina recte locum accipere medicina. Si numerus pulsus frequency occasus, ut medicina currus celeritate tardus non potest etiam fieri jitter, sonitus magnus, ad celeritatem ad adversa factores ut apparatus est necessarium efficientiam, ita adeo curvam motricium est. PLC dividitur in fixa et modularis (structurammodular). Fixum PLC inter CPU tabulas, I / o tabula, display panel, memoria caudices, potentia copia, etc. Modular PLC, inter CPU moduli, I / O module, memoria, aut chassis, potentia copia moduli, moduli potest esse secundum quaedam praecepta compositum configuratione. CPU est imperium centrum de PLC, per Arithmetica unitas, moderatoris, subcriptio, et consequi ea link inter notitia bus, imperium et statu. In modules accepto et collectione in signa ad CPU processus; Output moduli recipit indicium feliciter processionaliter per CPU control contactor digital display fabrica et output apparatu. Praeterea, in PLC programming fabrica usus est naturaliter user progressio, communiter handheld programming adhibetur ad parva plc programming, plerumque per computer, programming software) actum est. The international electrotechnical commission (IEC）In 1994 published the PLC programming language standard (IEC113123）, the standard defines the five PLC programming language: ladder diagram LAD (梯形图), statement table STL (本月吵闹列表), the function block diagram FBD (功能块图)ST, structure, text (圣生成文本), sequence function diagram SFC (顺序功能图)。 Use programming software can be directly on the screen are naturally and ladder diagram, sequence diagram editor program, and can realize the mutual transformation of different programming languages, program is compiled to download to the PLC's memory. PLC adopt the way of 'sequential scan, cycle', according to the user program memory, and CPU step according to the instruction sequence number (Number or address)A periodic cycle scanning, without interruption or jump instruction, the CPU start in order to perform a Detailed progressio, nam quisque signum inter logicam operationem, tandem eventus scriptum in output imaginem Register processus, signo et output output et virtute, ut in motricium output, electricity, ut in motricium motricium, electricity, ut in motricium motricium, motricium, et
mota, motricium motricium, motricium, et mota, motricium motricium, in motricium, et in electricity, motricium motricium, motricium, motricium motricium, motricium, et aliasque Motor Motor, Motor Motor et aliarum Models de stepper motricium, welcome ut inquire. Telephone:
