Chapter 10 DeviceNet Communication Module AH10DNET 10.10.3 Software Diagnosis When ISPSoft is used to read PLC system record, the following error codes may appear. 10-63 Code Indication How to deal with AH10DNET-5A is initializing. If initializing lasts too long, please repower AH10DNET-5A. E8 An error in the modules on the rack connected to AHRTU-DNET or the extension rack error 1. Check if the modules on the rack connected to AHRTU-DNET are normal. 2. Check if the extension rack connected to AHRTU-DNET is connected normally. E9 Error code Description How to deal with No slave is configured in the scan list Configure the slave in the scan list and then download the scan list to AH10DNET-5A.
16#A0F1 The node address of AH10DNET-5A is repeated in that of other node or exceeds the valid range. Ensure that the node address of AH10DNET-5A is unique and repower it after changing its node address. 16#A0F0 Excessively low voltage for AH10DNET-5A. Check if the work power for AH10DNET-5A and the AH500 series CPU module is normal. 16#A0F2 AH10DNET-5A enters the test mode. Switch IN1 from ON to OFF and repower AH10DNET-5A. 16#A0F3 AH10DNET-5A enters the bus-off state. 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 the same. 3.
Check if both ends of the network have been connected with a 121 Ω resistor respectively. 4. Repower AH10DNET-5A. 16#A0F4 No power for the DeviceNet network is detected. Make sure that the cable is correctly connected and check if the network power supply is normal. 16#A0F5 Internal storage unit errors in AH10DNET-5A If the error still exists after power on again, send your AH10DNET-5A back to the factory for repair. 16#A0F6 Data exchange unit errors in AH10DNET-5A If the error still exists after power on again, send your AH10DNET-5A back to the factory for repair.
16#A0F7 Sequence number detection errors in AH10DNET-5A If the error still exists after power on again, send your AH10DNET-5A back to the factory for repair. 16#A0F8 Errors 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. 16#A0F9 The node address of AH10DNET-5A is repeated in 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. Method 2: Do not configure any slave in the scan list.
Download the empty configuration to AH10DNET-5A by using the “Simulate online” function. Finally, repower it. 16#A0FA The data exchange between AH10DNET-5A and AHCPU fails. If the error still exists after AH CPU and AH10DNET-5A are repowered, send your AH10DNET-5A back to the factory for repair. 16#A0FB Some error occurs in the slave or in the modules on the rack connected to AHRTU-DNET or the 1. Check if the node address of the slave has been changed. 2. Check if the network cable is connected normally in case it is loose or cut. 16#A0FC
