Baton type of PLC control method, for example

Every problem has a ten thousand solution - — Write about the application of programmable controller, there are a variety of methods to achieve intended results. The correct method is: the program design and system assembly engineers can understand, can run, of course! The following method is a sequence of events in the procedure for another solution. Note: this method include simple pass mark 'the hand' program, program control like relay pass it on. When each of the provisions of the 'runner' to complete their journey, they pass a waiting for the 'control' 'runner'. The process of this program is also like that, when at the end of each section of the program, using a series of SET and RST instructions, be forced to pass to the next part of the program control. This method to control the number of steps without limit, as long as each part of the program has a separate/only 'good' mark. M and S coil can be used, even Y output will also provide the desired control.
