Corrective Action
1. Check the power to the CMM-DN02 and see if
the connection is normal.
2. Make sure there is at least one node on the
bus.
3. Check if the baud rate of the CMM-DN02 is the
same as that of the other nodes.
1. Configure the CMM-DN02 to the scan list of the
master.
2. Re-download the configured data to the
master.
No action is required.
1. Check if the network connection is normal.
2. Check if the master operates normally.
