This design introduced automatic round-trip work table PLC (programmable controller) the programming, including the PLC control module, the speed and the position feedback module as well as the safety control module and so on, has made the comprehensive elaboration and the induction to the entire control design summarizes, and proposes the improvement tentative plan. On the automatic production line, somewhat produces the machinery the work table to need according to certain smooth realization automatic reciprocating motion, and some also requests have certain time pause in certain positions, satisfies the production technological requirement. PLC was the recent years develops extremely rapidly, the application extremely widespread industry control device. PLC uses the programming language to pick easily from to study the easy to understand trapezoidal chart language, the control nimble convenient, antijamming ability, movement stable reliable and s
