plc中move的用法（plcmove是怎么控制的） - 原点资讯

MOVE：移动值

说明

可以使用“移动值”指令，将 IN 输入处操作数中的内容传送给 OUT1 输出的操作数中。始终沿地址升序方向进行传送。

如果满足下列条件之一，使能输出 ENO 将返回信号状态“0”：

使能输入 EN 的信号状态为“0”。
IN 参数的数据类型与 OUT1 参数的指定数据类型不对应。

REF()	不进行数据类型转换。所传递变量的数据类型必须与指定数据类型完全匹配。

1) 还可以使用“移动值”指令将字符串的各个字符传送到数据类型为 CHAR 或 WCHAR 的操作数。操作数名称旁的方括号内指定了要传送的字符数。例如，“MyString[2]”将传送“MyString”字符串的第二个字符。它还可以将数据类型为 CHAR 或 WCHAR 的操作数传送到字符串的各个字符中。还可使用其它字符串的字符来替换该字符串中的指定字符。

2) 仅当输入 IN 和输出 OUT1 中操作数的数组元素为同一数据类型时，才可以传送整个数组 (ARRAY)。

如果输入 IN 数据类型的位长度超出输出 OUT1 数据类型的位长度，则源值的高位会丢失。如果输入 IN 数据类型的位长度低于输出 OUT1 数据类型的位长度，则目标值的高位会被改写为 0。

在初始状态，指令框中包含 1 个输出 (OUT1)。可以扩展输出数目。在该指令框中，应按升序顺序排列所添加的输出。在执行指令过程中，将输入 IN 的操作数的内容传送到所有可用的输出。如果传送结构化数据类型（DTL、STRUCT、ARRAY）或字符串的字符，则无法扩展指令框。

还可以使用“块移动” (MOVE_BLK) 和“不可中断的存储区移动” (UMOVE_BLK) 指令移动 ARRAY 数据类型的操作数。可以使用“移动字符串”(S_MOVE) 指令复制 STRING 或 WSTRING 数据类型的操作数。
