任务 1 置位复位、上升沿下降沿指令

任务 1 置位复位、上升沿下降沿指令. 任务目标要求： 1 、掌握置位、复位指令基本形式和用法； 2 、掌握上升沿、下降沿指令的基本形式和用法。. 1 、置位与复位指令 SET 、 RST. SET ：置位指令，驱动线圈、寄存器置“ 1” 输出并保持。 RST ：复位指令，使线圈、寄存器置“ 0” 复位。. 2 、脉冲信号指令 PLS 、 PLF. PLS ：上升沿微分输出指令。在输入信号的上升沿产生一个扫描周期的脉冲输出。 PLF ：下降沿微分输出指令。在输入信号的上降沿产生一个扫描周期的脉冲输出。.

  2. 任务目标要求： 1、掌握置位、复位指令基本形式和用法； 2、掌握上升沿、下降沿指令的基本形式和用法。

  3. 1、置位与复位指令SET、RST SET：置位指令，驱动线圈、寄存器置“1”输出并保持。 RST：复位指令，使线圈、寄存器置“0”复位。

  4. 2、脉冲信号指令PLS、PLF PLS：上升沿微分输出指令。在输入信号的上升沿产生一个扫描周期的脉冲输出。 PLF：下降沿微分输出指令。在输入信号的上降沿产生一个扫描周期的脉冲输出。
