【正文】 t part. We know together as all movements of each step. (A+) mean that the active machine A pushes forward, but(A) means to return to the position of beginning. Sport of the simultaneous with is together fold to add in the same step. This system totally has five steps. Diagram 5 circulate with 6 systems for express clear of described all sequences. Make use of them, we can design with the essential logic language whole of control circuit. But now return it not just an integrity of system, because it is still in need of some assistance facilities, .(diagram in show) Circulate to the end of procedure, these assistance facilitieses are very important, because they can make the circuit have more functions. They win the most important is a conjunction in eachly the one step suddenly of parallel circuit. That circuit can stop a sequence and change the appearance of active machine into a particular position at any time. It can heavy system or cope with an urgent circumstance. Diagram 7 with 8 what to shows be some results that will take place under the sistuation that have no usage controller. These photographs are the electricity charts which controls circuit, include sensor, control key and give or get an electric shock of live petal book. Moreover some assistance facilities also include in this system, the for example automatic machine/ hand moves to adjust to control a machine, they can make system continuous of circulating work。 Two beginning control keys, they can let the operator hand move a beginning of control the system with stop, so reduced to take place an accident of danger. 6. The user changes an example programming Current of air coil fore the noodles has already elaborated on: It can let us understand to control the condition that a system need and that is in the actual movement in system and have to provide all function facilities. But, such as before speak of of so, use a PLC or particular controller, this kind of control bees more easy of, and the nicety of the system will also raise. The usage traditional PLC of, such as figure 7, 8 show, notice while draw electricity chart of connect the logic of circuit. The usage is this kind of programmable controller and the user needs to know to circulate the idea of the method and the structure of the programming each step. That is to say, use traditional PLC, the user knows the relation of of each operation. Under the general circumstance, User can before connecting a people39。s top to circulate 1 to imitate procedure to look for a logical mistake together say of similar, new of plait the distance allow an each one step suddenly of the structure be partition. The sequence is alone define, but each one step suddenly be carry by the input and output to describe. 7. Conclusion This kind of controller39。s ising specialized is what this item design. Showed 1 takes tiny controller as the programmable controller of basal great use. It doesn39。t need for obtaining the resources in the tiny controller but installing exterior memory a machine or exterior in fixed time a machine. In addition to tiny controller outside, only have a little amount of zero parts performance some like output, importation, type ratio importation, show a circumstance of connect the and continuous movement etc. function. Use inner part memory alone, we can control a current of air system which has 48 steps, but if use a more simple system, will attain 60 steps. The controller bees not to use PLC language, but use one more simple of with intuition of structure. Make use of electricity system, our items applied a same technique, but our designs be getting more direct in the meantime. A kind of very simple machine language can the one who let design use 4 or 5 byte definition a step all structure posing. This will see how experience that he use controller is .Although this kind of controller can39。t pare with the PLC of business, it is originally particular of of purpose but design of, so hard to say which good which bad. In fine, our this systems are in brief fast according to tiny controller but design.
