二、char 和 string 在西门子 PLC 中的格式 例如,在 PLC 中创建一个 DB 块,并将属性设置为标准 DB 块,在 DB1 块中创建如下的字符串和字符,并赋予起始值。如下图所示: 图.01 1、string 数据类型的格式 下载到 PLC 中,通过监视表逐个查看每个字节中的值。如下图所示: 图.02 可以看出: a.数据类型为 string
For what you write, I would start to imagine that the statement refers to the size of the string, so PLC side I imagine it as: MyString AT DB4455.DBB0 : STRING[19]. Check, possibly it will then be to correct.And then if you can do it, even better: check what it says in DB...

编程的过程中经常遇到需要将QString转成char *或者const char *的情况,在转换成QByteArray后调用.data()或者.constData()函数进行转换,这里需要注意的是,如果转换类型是const char *尽管用data()不会出错,会给你自动转换,但是还是不建议,因为深拷贝了一份,理论上增加了内存开销,如果字符串长度小还好,一旦很长,...
