DeviceNet Network Scanner DVPDNET-SL DVP-PLC Operation Manual 41 Code Indication How to correct E2 Slave device in the scan list does not exist or is offline. 1. Check if there is any change for the node address of the slave. 2. Check if the communication cable is disconnected or connected loosely. E3 DVPDNET-SL fails to transmit a message. Make sure that the connection is valid and check if the baud rate is correct. E4 Error detected in sequence of fragmented I/O messages from device Check if the slave is operating normally. E5 Slave device returns error when DVPDNET-SL attempts to communicate with it. Check if the slave is operating normally. E6 Data size returned is bigger than expected.
Check the configuration of slave device and scan list. E7 DVPDNET-SL is checking MAC ID. If the code is displayed long, do the troubleshooting according to the following steps. 1. Make sure that at least two nodes work normally in the network. 2. Check if either end of the network is connected with the terminal resistor of 121Ω. 3. Check if the baud rates of the node devices in the network are consistent with each other. 4. Check if the communication cable is normal so as to avoid that the cable is disconnected or connected loosely. 5. Re-power 10DNET scanner module.
