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.
