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.
