How to correct
Make sure that the power supply to
DVPDNET-SL is normal.
Make sure that there is at least one node
which can communicate with DVPDNET-SL
normally, at the same baud rate as
DVPDNET-SL on the network.
1. Ensure that the node address of
DVPDNET-SL is unique.
2. Re-power DVPDNET-SL.
1. Check if the network cable is correctly
connected to DVPDNET-SL.
2. Check the 24V DC network power.
Return to your factory or distributor for repair.
How to correct
--
Turn the PLC to RUN to start I/O data exchange.
1. Ensure that the node address of DVPDNET-SL is
unique.
2. Re-power DVPDNET-SL.
Configure the scan list and download it to
DVPDNET-SL.
Check if the power supply to the DVPDNET-SL and
PLC is normal.
Change IN1of the function switch from On to Off and
re-power the DVPDNET-SL.
1. Check if the network cable connection is proper.
2. Check if the baud rates of the nodes on the network
are consistent.
3. Re-power DVPDNET-SL.
1. Make sure that the cable is correctly connected.
2. Ensure that the power supply to the network is
normal.
If the error still exists after re-power, send your
DVPDNET-SL back to the factory for repair.
If the error still exists after re-power, send your
DVPDNET-SL back to the factory for repair.
If the error still exists after re-power, send your
DVPDNET-SL back to the factory for repair.
If the error still exists after re-power, send your
DVPDNET-SL back to the factory for repair.
1. Configure the network correctly and re-download it
to DVPDNET-SL.
2. Check if the node address of the slave in the scan
list is the same as the node address of
DVPDNET-SL.
