写入String类型数据提示【PlcRuntimeException: 尚未实现】

Question

我需要向PLC写入字符串、实数、整数、字节数据，但是写入字符串数据时会提示我 StaticHelper.serializeS7String 怎样才能满足我的要求？

我们最近有类似的报告，我们至少在 0.8.0-SNAPSHOT 中实现了所有这些类型的读取......也许可以试试这个版本。在读取字符串时...请注意 STRING 类型的新扩展语法...使用默认 PLC4X 时将加载字符串的所有 254 个字符，这目前会导致 S7 1200 设备出现问题。因此，请通过将最大数量添加到类型来限制字符串的大小：STRING(10) 将加载 10 个字符而不是 254 个。
