文本库中的文本ID。

《WinCC 信息系统》中是这样解释的：

dwMyTextID

Text ID of a text from the TextLibrary.

When the "FLAG_TEXTID_PARAMETER" is set, the text ID is provided as the numeric accompanying process value "8" of the message and is displayed as a number in process value block 8. So that the language-dependent text from the TextLibrary is displayed in the message, you must enter format statement "@8%s@" in the message text block.
