Creating an Extended Trend Log for b3 Point and Value Device Logs

Issue

Creating an Extended Trend Log for b3 Point and Value Device Logs

Need to get "Continuum" log information from b3 to StruxureWare

Environment

b3

Automation Server

Cause

You use an extended trend log to store log records for long periods of time. The extended trend log is often saved on a higher-level server with more storage capacity. This extra storage capacity enables the server to store more records before overwriting the old ones. For more information, see WebHelp. You configure extended trend logs for b3 BACnet devices the same way you configure extended trend logs in other Building Operation devices. There is one difference, however. You cannot use smart logs when configuring extended trend logs in b3 BACnet devices. Instead of using smart logs, you use the Maximum transfer interval property to specify the transfer interval.

Resolution

  1. In WorkStation, in the System Tree pane, expand the b3 BACnet device where you want to create an extended trend log.
  2. Select Application.
  3. In the List View, select the b3 BACnet device point or value that you want to transfer records from.
  4. On the File menu, click Properties.
  5. Click the Advanced tab.
  6. Multiply the Log records by the Log interval to calculate the maximum transfer interval.
  7. The maximum transfer interval is the frequency at which the extended trend log will transfer log records from the b3 point or value before any entries in the controller log are overwritten. 
  8. In the System Tree pane, expand the b3 BACnet device.
  9. Select Application.
  10. On the File menu, point to New and then click Trend.
  11.  In the object type list, select Extended Trend Log and then click Next.
  12.  In the Monitored trend log box, enter the b3 point or value that you want to transfer records from.
  13.  In the Smart log box, select False
  14. In the Maximum transfer interval dropdown box, select a maximum transfer interval less than the one calculated in step 6. The maximum transfer interval supercedes the threshold.
  15. Click Create.
