About Updating Tag Properties Dynamically
When you add or delete tags for a collector, or when you modify the properties of the tags or the collector using the offline configuration file, the changes are reflected without the need to restart the collector.
- This is applicable only to bi-modal collectors.
- The changes are reflected in 90 seconds.
- Access the offline configuration file for the collector. By default, this file is available in the following location: <installation folder of Historian>\GE Digital\<collector name>. For example, for the simulation collector, the path to the file is C:\Program Files (x86)\GE Digital\Historian Simulation Collector\Config\Sim_Offline_Config.xml.
- Inside the
<collector>
element, for the<DisableOnTheFlyTagChanges>
parameter, enter Yes, and save the file. By default, the value is No.Tip: To verify that the changes are saved, verify the .shw file for the collector.
Troubleshooting
By default, the offline configuration file is continuously monitored for any changes in the tag names and/or properties, and the changes are reflected dynamically. If, however, the changes are not reflected, you can create the following registry key to fix the issue: OfflineTagForceCheckDuration
