变量类型STRING用于字符串,CODESYS默认为80个字节。STRING以ASCII(8位)解释,WSTRING以UNICODE(16位即UTF-16编码)解释。 STRING 变量需要的内存一直是: STRING: 1字节/字符 + 额外1字节用于零终止 WSTRING: 2字节/字符 + 额外2字节用于零终止
定义宽字符串变量的赋值应该将字符串放在两个单引号内,此与String字符串一样;②宽字符串支持中文字符串赋值,其由Unicode解码;③对于String字符串,只能支持ASCII码字符串;④在指定字符串大小时,宽字符串与String字符串相比,更占存储空间,宽字符串所占存储空间为2×(N+1)字节(Byte),String字符串为N+1字节(Byte)...
