Chapter 10 DeviceNet Communication Module AH10DNET 10.10.2 Seven-segment Display Diagnosis 10-61 LED status Indication How to deal with NS MS Duplicate ID detection has not completed. Ensure that at least one node and AH10DNET-5A have the same baud rate and communicate normally on the network. Green OFF light ON Duplicate ID detection failed or bus-off. 1. Ensure that the node address of AH10DNET-5A is unique. 2. Repower it. Red light Green ON light ON No network power 1. Check if the network cable connection is correct. 2. Check if the network power is normal. Red light Red light ON blinking Red light Red light Hardware error Return it to the factory for repair.
ON ON Code Indication How to deal with Node address of DVPDNET-SL (in normal operation) -- 0~63 AH10DNET-5A in STOP status. Turn the AH500 series CPU module to RUN and start I/O data exchange. 80 The node address of AH10DNET-5A is identical to that of other node or exceeds the valid range. 1. Ensure that the node address of AH10DNET-5A is unique. 2. Repower it after changing its node address. F0 No slave device is configured in the scan list of AH10DNET-5A Configure the slave in the scan list and download the scan list to AH10DNET-5A. F1 Excessively low voltage for AH10DNET-5A Check if the power supply for AH10DNET-5A and the AH500 series CPU module is normal.
F2 Entering test mode Switch IN1 from ON to OFF and repower AH10DNET-5A. F3 Bus-off 1. Check if the network cable is normal and the shielded wire has been grounded. 2. Check if the baud rates of all node equipment on the network are consistent. 3. Check if both of the two ends of the network have a 121 Ω resistor. 4. Repower AH10DNET-5A. F4 No network power Make sure the cable is correctly connected and check if the network power is normal. F5 Internal errors; internal memory unit errors If the error still exists after power on again, send your AH10DNET-5A back to the factory for repair.
F6 Data exchange unit errors If the error still exists after power on again, send your AH10DNET-5A back to the factory for repair. F7 Sequence number detection errors If the error still exists after power on again, send your AH10DNET-5A back to the factory for repair. F8 An error in reading/writing the configuration data. If the error still exists after power on again, send your AH10DNET-5A back to the factory for repair. F9 The node address of AH10DNET-5A is the same as that of the slave configured in the scan list. Method 1: Reset the node address of AH10DNET-5A, which must be different from that of the slave configured in the scan list and then repower it. FA
