I have used stadandard project Long term Archiving It works fine and I tested it with 24 tags to be logged for long term logging. Now the matter is that I don't want to display all tags on history trend I just want to show only trend of those tags selected from symbolic IO fields, say (6 tags). Although this strategy of showing trend is successful in realtime trend view but does't fit for history trend. Attached pic contains view how I have implemented it for real time but I am unable to do so for history trend. More over when I call tag directly for logged file then its history trend is successfully retrieved for the log but when I call a tag from Symbolic IO field using script it fails to show its logged trend. On the other side same pattern of displaying trend is working fine in case of realtime trend view. Does WinCC flexible doesn't support scripts to call logged tags or I am doing something wrong? Best Regards Waseem |
