It is normal for the "Device Not Ready" message to be displayed after a device is first added to a field unit, indicating that the device is in the process of being added. This process can take up to 10-15min. If the "Device Not Ready" error persists after 30min, it is likely that:

• The device or cable is drawing too much current
• The configuration of the device is incorrect
