巧用移位寄存器位指令实现流水线的自动控制

Realization of the Automatic Control of Assembly Line Based on SHRB of STEP 7-Micro/Win Software

以某车间流水线为例,在输入信号脉冲间隔小于所需延时时间的情况下,巧妙利用S7-PLC移位寄存器位(SHRB)指令实现流水线的动作控制。

Taking a workshop assembly line as an example, achieve control of the assembly line while the input signal pulse inter- val is less than the required delay.
