12.3.7 Troubleshooting for AH10DNET-5A

The parameters which are mentioned in the table below are set in DeviceNet Builder version 1.07 or above.
Error
Description
code
The node ID of AH10DNET-5A
is the same as other node ID on
16#A0F0
the network, or exceeds the
range.
No slave is put on the scan list
16#A0F1
of AH10DNET-5A.
The working voltage of
16#A0F2
AH10DNET-5A is low.
AH10DNET-5A enters the test
16#A0F3
mode.
The bus of AH10DNET-5A
16#A0F4
becomes OFF.
AH10DNET-5A detects that
16#A0F5 there is no power supply to the
DeviceNet network.
Something is wrong with the
16#A0F6 internal memory of
AH10DNET-5A.
Something is wrong with the
16#A0F7 data exchange unit of
AH10DNET-5A.
The product ID of
16#A0F8
AH10DNET-5A is incorrect.
An error occurs when the data
is read from AH10DNET-5A, or
16#A0F9
when the data is written into
AH10DNET-5A.
The node ID of AH10DNET-5A
16#A0FA is the same as that of the slave
set on the scan list.
The data exchange between
16#A0FB
AH10DNET and AH CPU failed.

Remedy
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.
Put slaves on the scan list, and then download the scan list
to AH10DNET-5A.
Check whether the working voltage of AH10DNET-5A and
that of an AH500 series CPU module are normal.
Switch IN 1 on the module OFF, and supply power to
AH10DNET-5A again.
1. Check whether the communication cable is normal, and
whether the shielded cable is grounded.
2. Check whether the serial transmission speeds of other
devices on the network are the same.
3. Check whether the both ends of the cable are
connected to 121 Ω terminal resistors.
4. Supply power to AH10DNET-5A again.
Check whether the communication cable is normal, and
whether the network power supply is normal.
Supply power to AH10DNET-5A again. If the error still
occurs, please contact the local authorized distributors.
Supply power to AH10DNET-5A again. If the error still
occurs, please contact the local authorized distributors.
Supply power to AH10DNET-5A again. If the error still
occurs, please contact the local authorized distributors.
Supply power to AH10DNET-5A again. If the error still
occurs, please contact the local authorized distributors.
Method 1: Set the node ID of AH10DNET-5A again. The
new node ID can not be the same as the node ID of the
slave set on the scan list. Supply power to AH10DNET-5A
again.
Method 2: Put no slave on the scan list, and download the
blank scan list to AH10DNET-5A through the simulated
online mode in the software. Supply power to
AH10DNET-5A again.
Supply power to the AH10DNET and AH CPU and try to
exchange data again. If the issue continuses, contact the
local authorized distributors.
