| Abstract: | The element and operation number setting up and the mode of inputing and outputting of DSW function instruction, SEGL function instruction and ARWS function instruction which are function instruction of Japanese Mitsubishi programmable controller are introduced. Applying combination of these instructions, timer and counter initial value modification and current value show control procedure realize timer and counter initial value modification convenient and current value manifestation accurate and operation vivid. Take initial value modification and current value manifestation of counter as an example, a ladder diagram is given and the system good function by emulation adjusting experiment result is proved. |
