1. Check if the network cable is normal and the
2. Check if the baud rates of all node equipment
3. Check if both of the two ends of the network
4. Repower AH10DNET-5A.
How to deal with
Ensure that at least one node and
AH10DNET-5A have the same baud rate
and communicate normally on the network.
1. Ensure that the node address of
AH10DNET-5A is unique.
2. Repower it.
1. Check if the network cable connection is
correct.
2. Check if the network power is normal.
Return it to the factory for repair.
How to deal with
--
Turn the AH500 series CPU module to RUN
and start I/O data exchange.
AH10DNET-5A is unique.
Configure the slave in the scan list and
download the scan list to AH10DNET-5A.
Check if the power supply for AH10DNET-5A
and the AH500 series CPU module is normal.
Switch IN1 from ON to OFF and repower

Make sure the cable is correctly connected and
check if the network power is normal.
If the error still exists after power on again, send
your AH10DNET-5A back to the factory for
repair.
If the error still exists after power on again, send
your AH10DNET-5A back to the factory for
repair.
If the error still exists after power on again, send
your AH10DNET-5A back to the factory for
repair.
If the error still exists after power on again, send
your AH10DNET-5A back to the factory for
repair.
Method 1: Reset the node address of
AH10DNET-5A, which must be different from
that of the slave configured in the scan list and
then repower it.
