8-3-4 LED Indicator & Troubleshooting
There are two LED indicators on the CMM-DN02: NS LED and MS LED. NS LED and MS LED are
dual-color LEDs, displaying the connection status and error messages of the communication module.
NS LED
No power supply or the CMM-DN02
does not pass the MAC ID test.
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.
The CMM-DN02 is on-line but does
not connect to the master.
1. Configure the CMM-DN02 to the scan list of the
master.
2. Re-download the configured data to the
master.
The CMM-DN02 is on-line and
normally connects to the master.
The CMM-DN02 is on-line, but I/O
connection is timed-out.
1. Check if the network connection is normal.
2. Check if the master operates normally.
