摘要
对于PLC双线圈输出的问题进行了探讨 ,并结合实例阐明了在一般情况下 ,PLC是不允许双线圈输出的 ;但在用步进梯形指令控制的程序里 ,PLC允许双线圈输出 ;对于用转移指令控制的程序 ,只要编程得当 。
The problem of multicoil output of PLC have been studied.With the living examples,the paper pointed out that multicoil output is not permitted in common.But it is allowed in the PLC programs which are controlled by STL instruction and if it is used properly it is also allowed in the PLC programs which are controlled by transfer instruction.
