If no points appear in the list of the Wizard Auto Detect Utility during the auto-discovery procedure, the reference to the VMD file in parameter 8 of the device's vendor configuration data may be incorrect.

Error messages appear in the Protocol Description field on the Hardware tab of the integration object. See Table 1 for a description of possible error messages. If you receive an error not shown in Table 1, contact the supplier of the VMD file for assistance.

Also, if auto-discovery problems persist, follow these steps:

  1. Send a Disable command to the Modbus integration object.
  2. Update or correct the resource file in the integration.
  3. Send an Enable command to the Modbus integration object.
  4. Try the auto-discovery process again.
