AH500 Module Manual 10-62 Code Indication How to deal with Method 2: No slave is configured in the scan list. Download the empty configuration to AH10DNET-5A by using the “Simulate online” function. Finally, repower it. 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. FB AH10DNET-5A has detected that the node equipment on the bus is different from that in the scan list. 1. Check if the node address of the slave has been changed. 2. Check if the node equipment on the bus has been changed. 3. Configure the network again.
E0 The actual polled data length in the slave is not consistent with that set in the scan list. 1. Check the actual IO data length of the slave. (Please see section 10.9.2.) 2. Configure relevant slaves to the scanner module again. E1 The slave in the scan list is offline or does not exist when in master mode. 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. 3. Check if the bus communication cable length exceeds the maximum transmission distance. If it does, the system will no longer keep stable. (See section 10.3.3.) E2 10DNET slave module is disconnected to the IO of master when in slave mode.
AH10DNET-5A fails to transmit a message. 1. Check if the connection between the scanner module and network is normal 2. Ensure that the baud rates of the scanner module and other node are same. E3 An error detected in sequence of fragmented I/O messages from the slave device Check if the slave is operating normally. E4 The slave device returns error messages when AH10DNET-5A attempts to communicate with it. Check if the slave is operating normally. E5 The size of IO data returned from the slave is greater than that configured in the scan list. Ensure that the IO data length of the slave is the same as that configured in the scan list.
E6 AH10DNET-5A is checking if its node address is repeated in that of other node equipment on the network Please follow the methods below to shoot the troubles if the error code appears for long. 1. Ensure that at least two nodes work normally on the network. 2. Check if both ends of the network are connected with 121 Ω terminal resistors respectively. 3. Ensure that the baud rates of all node equipment are same. 4. Check if the network cable is connected normally in case it is loose or cut. 5. Check if the bus communication cable length exceeds the maximum transmission distance. The system may no longer keep stable if the maximum distance is exceeded. 6.
Check if the shielded wire in the network communication cable is grounded. 7. Repower AH10DNET-5A. E7
