發布日期:2022-04-26 點擊率:223 品牌:歐姆龍_Omron

    歐姆龍CPM1A系列PLC的異步移位寄存器指令ASFT/@ASFT


    C:控制數據St:移位開始通道E:結果通道

    C的含義

    指令功能

    當執行條件為ON時,將數據為0000的通道與相鄰通道進行數據交換。

    執行指令ASFT時數據交換的規則

    ①相鄰兩通道數據都為0000,不交換。

    ②上移:數據為0000的通道與相鄰高地址通道交換。

    ③下移:數據為0000的通道與相鄰低地址通道交換。

    執行指令ASFT,可以把數據為0000的通道集中到數據區的上半部分或下半部分。

    使用指令ASFT舉例
