Indication
How to deal with
E8
AH10DNET-5A is initializing.
If initializing lasts too long, please repower
AH10DNET-5A.
E9
An error in the modules on the
rack connected to
AHRTU-DNET or the extension
rack error
1. Check if the modules on the rack connected
to AHRTU-DNET are normal.
2. Check if the extension rack connected to
AHRTU-DNET is connected normally.
10.10.3 Software Diagnosis
When ISPSoft is used to read PLC system record, the following error codes may appear.
Error code
Description
How to deal with
16#A0F1
No slave is configured in
the scan list
Configure the slave in the scan list and then download
the scan list to AH10DNET-5A.
16#A0F0
The node address of
AH10DNET-5A is
repeated in that of other
node or exceeds the valid
range.
Ensure that the node address of AH10DNET-5A is
unique and repower it after changing its node address.
16#A0F2
Excessively low voltage
for AH10DNET-5A.
Check if the work power for AH10DNET-5A and the
AH500 series CPU module is normal.
16#A0F3
AH10DNET-5A enters the
test mode.
Switch IN1 from ON to OFF and repower
AH10DNET-5A.
16#A0F4
AH10DNET-5A enters the
bus-off state.
1. Check if the network cable is normal and the
shielded wire has been grounded.
2. Check if the baud rates of all node equipment on the
network are the same.
3. Check if both ends of the network have been
connected with a 121 Ω resistor respectively.
4. Repower AH10DNET-5A.
16#A0F5
No power for the
DeviceNet network is
detected.
Make sure that the cable is correctly connected and
check if the network power supply is normal.
16#A0F6
Internal storage unit
errors in AH10DNET-5A
If the error still exists after power on again, send your
AH10DNET-5A back to the factory for repair.
16#A0F7
Data exchange unit errors
in AH10DNET-5A
If the error still exists after power on again, send your
AH10DNET-5A back to the factory for repair.
16#A0F8
Sequence number
detection errors in
AH10DNET-5A
If the error still exists after power on again, send your
AH10DNET-5A back to the factory for repair.
16#A0F9
Errors in reading/writing
the configuration data
If the error still exists after power on again, send your
AH10DNET-5A back to the factory for repair.
16#A0FA
The node address of
AH10DNET-5A is
repeated in that of the
slave configured in the
scan list.
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.
Method 2: Do not configure any slave in the scan list.
Download the empty configuration to AH10DNET-5A
by using the “Simulate online” function. Finally, repower
it.
16#A0FB
The data exchange
between AH10DNET-5A
and AHCPU fails.
If the error still exists after AH CPU and AH10DNET-5A
are repowered, send your AH10DNET-5A back to the
factory for repair.
16#A0FC
Some error occurs in the
slave or in the modules
on the rack connected to
AHRTU-DNET or the
1. Check if the node address of the slave has been
changed.
2. Check if the network cable is connected normally in
case it is loose or cut.
