/**
* 向 PLC S7 写入数据
* <p>
* 该方法用于将指定类型的数据写入到 PLC S7 的指定点位。
* 1. 根据类型字符串获取对应的 {@link AttributeTypeFlagEnum} 枚举值。
* 2. 如果类型不支持, 抛出 {@link UnSupportException} 异常。
* 3. 根据类型将字符串值转换为相应的 Java 类型。
* 4. 使用 {@link S7Serializer} 将数据写入到 PLC S7 的指定数据块和字节偏移量位置。
* <p>
* 支持的数据类型包括：
* - INT: 整型
* - LONG: 长整型
* - FLOAT: 单精度浮点型
* - DOUBLE: 双精度浮点型
* - BOOLEAN: 布尔型
* - STRING: 字符串
*
* @param serializer S7 序列化器, 用于与 PLC S7 进行数据交互
* @param plcS7PointVariable PLC S7 点位变量信息, 包含数据块编号, 字节偏移量等
* @param type 数据类型字符串, 用于标识要写入的数据类型
* @param value 要写入的字符串形式的数据值
* @throws CommonException 如果数据类型不支持, 抛出此异常
