5.Troubleshooting Ethernet LED DVP10MC11T has two Ethernet LED indicators like orange light and green light. Green light indicates the Ethernet communication state and orange light indicates Ethernet baud rate. COM 1 LED COM1 LED is an indicator of RS-232 communication port of PLC module. It indicates the communication state of RS-232 communication port of PLC module. COM 2 LED COM2 LED is the indicatior of RS-485 shared by motion control module and PLC module to indicate the state of RS-485 communication port. DVP-MC operating manual 5-3 LED state Explanation How to deal with Green light flash The communication with the axis configured is not ready.
Check if the communication with each axis is normal. Red light on Hardware error in MC module After power on once again, return the goods to factory for repair if the error still exists. Red light blinking MC module runs abnormally 1. Check if the setting value for synchronization cycle is too small. After increasing the synchronization cycle value, re-download. 2. Check if there is slave offline in CANopen network. 3. Check if the motion control program is stopped after it is executed. 4. Check if there are unsupportive instructions in the program.
LED State Indication Orange light Light on Ethernet baud rate:100Mbps Light off Ethernet baud rate is 10Mbps or 10MC has not been put in Ethernet. Green light Light flash The Ethernet communication port for 10MC is receiving and sending data. Light off The Ethernet communication port for 10MC is not receiving and sending data. LED state Indication Yellow light flash There is response data at RS-232 (COM1) port. Light off There is no response data at RS-232 (COM1) port . RUN LED state Indication Yellow light flash There is response data at RS-485 (COM2) port. Light off There is no response data at RS-485 (COM2) port.
