The following problems were found when using wincc's own system messages.
When the user logs in, the text recorded in the system message is USERT:@100%s@: the @100%s@ for manual login here should be the computer name, and it is also the recorded computer name during actual use. Personally, I think the text generated by USERT:@102%s@: manual login is more in line with the meaning of this message.
When checking the system messages, it is found that some alarm messages have placeholders such as @1%s@ @2%s@, and the intermediate values in these processes conflict with the user-defined parts, which will cause ambiguity when displayed in the operation record.
