Chapter 9 Troubleshooting
9.2.7 Troubleshooting for AH10DNET-5A
The parameters which are mentioned in the table below are set in DeviceNet Builder version 1.07 or above.
Error
code
Description Remedy
16#A080 AH10DNET-5A stops running.
Switch the operating status of the CPU module to the
running status.
AH10DNET-5A functions as a
master. The slave in the scan
list is disconnected or does not
exist.
1. Check whether the node ID of the slave changes.
2. Check whether the communication cable is disconnected
or loose.
3. Check whether the length of the cable is larger than the
maximum transmission distance. If the length of the
cable is larger than the maximum transmission distance,
the stability of the system can not be ensured.
16#A0E2
AH10DNET-5A as a slave does
not connect to the I/O module
as a master.
1. Check whether the node ID of the slave changes.
2. Check whether the communication cable is disconnected
or loose.
3. Check whether the length of the cable is larger than the
maximum transmission distance. If the length of the
cable is larger than the maximum transmission distance,
the stability of the system can not be ensured.
16#A0E7
AH10DNET-5A is checking
whether its node ID is the
same as the node ID of other
device on the network.
If the error has occurred for a long time, please eliminate
the error in the following way.
1. Make sure that there are at least two nodes working
normally on the network.
2. Check whether the both ends of the cable are connected
to 121 terminal resistors.
3. Check whether the serial transmission speeds of other
devices on the network are the same.
4. Check whether the communication cable is disconnected
or loose.
5. Check whether the length of the communication cable is
larger than the maximum transmission distance. If the
length of the communication cable is larger than the
maximum transmission distance, the stability of the
system can not be ensured.
6. Check whether the shielded cable is grounded.
7. Supply power to AH10DNET-5A again.
16#A0E8
AH10DNET-5A is being
initialized.
If the error has occurred for a long time, please supply
power to the module again.
16#A0F0
The node ID of AH10DNET-5A
is the same as other node ID on
the network, or exceeds the
range.
Make sure that the node ID of AH10DNET-5A is the only
one on the network. If the node ID of AH10DNET-5A is not
the only one on the network, please change the node ID,
and supply power to AH10DNET-5 again.
16#A0F1
No slave is put on the scan list
of AH10DNET-5A.
Put slaves on the scan list, and then download the scan list
to AH10DNET-5A.
16#A0F2
The working voltage of
AH10DNET-5A is low.
Check whether the working voltage of AH10DNET-5A and
that of an AH500 series CPU module are normal.
16#A0F3
AH10DNET-5A enters the test
mode.
Switch IN 1 on the module OFF, and supply power to
AH10DNET-5A again.
