Datalink Configuration
Scenario: The application displays “Variable invalid or data link missing” error message while configuring the Data Link for a variable.
Root Cause
: The message “Variable invalid or data link missing” typically occurs due to one of the following root causes:- Cause 1: No Data Link Configured for the Variable- The meter associated with this variable does not have a valid data link configured.Solution: Perform the following steps to edit the configuration and assign the valid data links:
- Open the variable configuration in the application.
- Assign a valid data link to the meter.
- Save the configuration and verify that the error message no longer appears.
- Cause 2: Associated Timeseries Deleted- The timeseries linked to the meter configuration was removed from the system (e.g., deleted in CDF), causing the data link to become invalid.Solution: Perform the following steps to verify and reconfigure a valid timeseries:
- Check if the timeseries exists in CDF.
- If missing, recreate the timeseries or select an alternative valid timeseries.
- Update the meter configuration to point to the correct timeseries.
- Save and validate the configuration.
