WinCC v7.4 Step By Step #18: WinCC Tag Logging 📈  

Yes it is. All tag logging configuration is done on the server. the clients all connect to the project through the server and can show trends, etc.

Hi : The Alarm Logging Message Text above is pulling in a live process value from Process Value block number 1 as an integer (d). The @ signs at beginning and end are delimiters. If you look at the alarm message were this message text came from, there will be a tag assigned to Process value Block #1 which provides the integer data. So when the alarm occurs, the message text will look like: "failure feeding unit (3)" given that the defined tag value in process value block # 1 is value = 3 at the moment of the alarm. As for 'Xref D4.4' -- can you give me some context? is it part of the alarm message?

@@WinCCGURU Yes Sir for WinCC V7.0 it has Xref column too.

@@vorapobautomation9760 its likely a text block (xRef) column and the D4.4 is a cross reference value or address put there to help determine the cause of the alarm; but without seeing the project I couldn't say.

Yes. As well as tag logging data

@@WinCCGURU any video available, how tag logging data gets stored in sql?

Working on it 😀
