| 摘 要： | 在电厂输配煤远程监控系统中，液动卸料器的配仓动作控制是典型的复杂逻辑控制，对此，本文给出一种完成配仓功能的具体实现方法，该方法摒弃线圈直接输出而采用微机通用处理方式，同时又充分考虑PLC不同于其它控制器的扫描执行特点，为解决复杂逻辑任务提供一种简便的开发思路，给编程带来灵活性，该方法可在PLC的其它应用场合推广。

| Abstract: | It is typical complex logic control that the hydraulic plow distributes the coal to the silo. A method to realize the distribution of coal to silo was introduced. Direct output method was given up and common computer concept was used in this method, for instance Set/Reset/Move instruction etc. The flexibility and extending value was presented. |
