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。
参数
下表列出了“移动值”指令的参数:
参数 | 声明 | 数据类型 | 存储区 | 说明 | |
---|---|---|---|---|---|
S7-1200 | S7-1500 | ||||
EN | Input | BOOL | BOOL | I、Q、M、D、L 或常量 | 使能输入 |
ENO | Output | BOOL | BOOL | I、Q、M、D、L | 使能输出 |
IN | Input | 位字符串、整数、浮点数、定时器、日期时间、CHAR、WCHAR、STRUCT、ARRAY、IEC 数据类型、PLC 数据类型 (UDT) | 位字符串、整数、浮点数、定时器、日期时间、CHAR、WCHAR、STRUCT、ARRAY、TIMER、COUNTER、IEC 数据类型、PLC 数据类型 (UDT) | I、Q、M、D、L 或常量 | 源值 |
OUT1 | Output | 位字符串、整数、浮点数、定时器、日期时间、CHAR、WCHAR、STRUCT、ARRAY、IEC 数据类型、PLC 数据类型 (UDT) | 位字符串、整数、浮点数、定时器、日期时间、CHAR、WCHAR、STRUCT、ARRAY、TIMER、COUNTER、IEC 数据类型、PLC 数据类型 (UDT) | I、Q、M、D、L | 传送源值中的操作数。 |
示例
以下示例说明了该指令的工作原理:
下表将通过具体的操作数值对该指令的工作原理进行说明:
参数 | 操作数 | 值 |
---|---|---|
IN | TagIn_Value | 0011 1111 1010 1111 |
OUT1 | TagOut_Value | 0011 1111 1010 1111 |
如果操作数“TagIn”返回信号状态“1”,则执行该指令。该指令将操作数“TagIn_Value”的内容复制到操作数“TagOut_Value”,并将“TagOut”的信号状态置位为“1”。
