Change MAC ID
A device Media Access Control Identifier (MAC ID) represents the device address on the DeviceNet network. The MAC ID range is 0 to 63. If multiple devices use the same MAC ID, only one device can work properly. To resolve a MAC ID conflict, you must change the device MAC ID.
Complete the following steps to change the MAC ID:
- Select Device»Change MAC ID.
- Enter the new MAC ID and click OK. After you change the MAC ID, the configurator uploads all parameters from the device.
