Hi,
If you’re not seeing tags and the connector shows no connection, the issue is usually at the Databus / Edge / IIH connectivity layer, not in Mendix itself.
Since you mentioned Databus is configured with ToICS Edge, check the following step by step:
1. Verify Edge connectivity
Even if configured, Edge must be actively connected and running.
Check:
- Edge service status (running)
- Connection to IIH (no firewall/proxy blocking)
- Correct tenant and environment
If Edge is not connected → no tags will be visible.
2. Check asset & tag publication
Tags only appear if they are published to IIH.
Verify:
- Assets are created in Databus
- Tags are mapped and published
- Data is actually flowing (not just configured)
In many cases, tags exist in MES but are not published to IIH.
3. Validate Flow Creator connection
In Flow Creator:
- Check connector status (should be “Connected”)
- Re-authenticate if needed
- Try refreshing/recreating the connector
If connection is broken → tags won’t load.
4. Permissions / access rights
Make sure:
- Your user has access to the assets/tags in IIH
- Correct roles are assigned
No access = no tags visible.
5. Check naming / namespace consistency
If using ToICS Edge:
- Tag names / namespaces must match exactly
- Incorrect mapping → tags won’t appear in IIH
6. Look at logs (important)
Check:
- Edge logs (data ingestion issues)
- IIH logs (connection/auth errors)
- Flow Creator logs (connector errors)
7. Quick validation test
Try:
- Sending a test tag/value manually
- Check if it appears in IIH
If not → issue is before Mendix/Flow Creator.
If no tags are visible and connection is not established, the root cause is typically:
- Edge not properly connected
- Tags not published to IIH
- Connector authentication/permissions issue
Focus on validating Edge → IIH → Flow Creator connection chain, and the tags should start appearing.
