Ensure that the node address is unique and
repower it after modifying the node address.
Configure the module and then download it to
AHRTU-DNET-5A.
Check if the work power of AHRTU-DNET-5A is
normal.
Repower AHRTU-DNET-5A.
1. Check if the network cable is normal and the

Ensure that the network is normal and
re-download the configuration; ensure the node
address of AHRTU-DNET-5A is different from
that of other node.
The corresponding module connected to the rack
slot is in error state; check if the corresponding
module alarms or is bus-off or does not fit the
configured module or has been added to the scan
list.
