Issue
Report or Extended Trend Log not showing the most recent data
Product Line
EcoStruxure Building Operation
Environment
- Interval Trend Logs
- Extended Trend Logs
Cause
The extended trend log will only pull information from the Trend log when the Threshold is reached.
Resolution
OPTION 1 - Use the maximum Transfer Interval property.
- Edit the Extended Trend Log
- Change the Maximum Transfer Interval property from "Disabled" to the maximum time you want to go between updates in the extended trend log.
NOTE: You should not set every extended trend log to 1 minute as this will cause unneeded strain to the system. If you need current data, look at the Trend Log. Use Extended Trend Logs and Reports for Historic information.
OPTION 2 - Use the Transfer trigger variable
- Create a Digital Value on the Enterprise Server. This can be controlled by a program or a schedule to force the Extended trend log to update before reports are run
- Edit the Extended Trend Log
- Set a the Transfer trigger variable as the Digital Value created above.
There are many options with Extended Trend Logs, see System Reference Guide chapter 40.
Additional Notes
1. Extra care should be taken when configuring B3 and Infinet Extended Trend Logs - See Technical Reference Guide for full details.
"You configure extended trend logs differently in Infinet (and b3) devices than you
configure extended trend logs in other EcoStruxure Building Operation devices.
For example, you bind the Monitored trend log property to the Infinet device (and b3)
point or value configured for trend logging. Also, the Threshold property is not
relevant when monitoring extended trend logs regardless of the value you
specify. Finally, you cannot use smart logs when configuring extended trend
logs in Infinet devices (and b3).
Instead of using smart logs, you use the Maximum transfer interval property to
specify the transfer interval." (Technical Reference)
2. To debug logging issues the Force transfer is very helpful, Force transfer Executed by the user to manually force a transfer even though transfer threshold is not reached. (Right click on the Extended Trend Log/Activation/Force Transfer)
