I have configured Factory SQL for WINCC SCADA Server.
There are two issues that I am encountering.
In a group intended for Milk Reception for certain route, I am getting the tag value for Route_Name as “E_UNKNOWN_ITEM_NAME”. A few days ago, when I configured that tag, value is coming properly. Same is happening for another tag.
I am writing a tag for resetting and setting Utility at midnight (DB to OPC). It was working properly before. But now, it is showing value as “Config Error”.
Can you suggest what can be the causes for the problem mentioned, so we can resolve the same.
I am attaching the screen shot of the errors along with this post.
Waiting for your kind reply.
Thanks and Regards,
