DeviceNet Network Scanner DVPDNET-SL

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.
