Troubleshooting Data Imports

If you experience problems with a data import and want to resolve them, try the following steps:

• Ensure that the time stamps of any online archives are not prior to the start time of the oldest online archive.
• Ensure that the time stamps are within the active hours setting in the Data Store Maintenance screen of the Historian Administrator.
• Ensure that the time stamps are not for a time greater than 15 minutes ahead of the system time on the Historian Server.
• Ensure that the tags are valid Historian tags. To do this, import your tags before importing their associated data.
