Indication
Device key parameter does
not match the scan list
table.
Data size returned does not
match the scan list.
Slave device in the scan list
does not exist or is offline.
DVPDNET-SL fails to
transmit a message.
Error detected in sequence
of fragmented I/O
messages from device
Slave device returns error
when DVPDNET-SL
attempts to communicate
with it.
Data size returned is bigger
than expected.
DVPDNET-SL is checking
MAC ID.
How to correct
Make sure that the device parameter in the scan list
matches the desired key parameter, including vendor
ID, product code, device type and version.
Re-configure the scan list using correct data size.
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.
Make sure that the connection is valid and check if the
baud rate is correct.
Check if the slave is operating normally.
Check if the slave is operating normally.
Ensure that the size of the IO data of the slave is the
same as that configured in scan list.
If the code is displayed long, do the troubleshooting
according to the following steps.
1. Make sure that at least two nodes work normally on
the network.
2. Check if both ends of the network are connected
with a terminal resistor of 121Ω respectively.
3. Check if the baud rates of the node devices on the
network are identical.
4. Check if the communication cable is normal so as to
avoid that the cable is disconnected or connected
loosely.
5. Re-power the DVPDNET-SL module.
