The data exchange between
FB AH10DNET-5A and AHCPU
fails.
AH10DNET-5A has detected
that the node equipment on the
E0
bus is different from that in the
scan list.
The actual polled data length in
E1
the slave is not consistent with
that set in the scan list.
The slave in the scan list is
offline or does not exist when in
master mode.
E2
10DNET slave module is
disconnected to the IO of master
when in slave mode.
AH10DNET-5A fails to transmit a
E3
message.
An error detected in sequence of
E4 fragmented I/O messages from
the slave device
The slave device returns error
E5 messages when AH10DNET-5A
attempts to communicate with it.
The size of IO data returned
E6 from the slave is greater than
that configured in the scan list.
AH10DNET-5A is checking if its
node address is repeated in that
E7
of other node equipment on the
network
1 0 - 6 2
Indication
Method 2: No slave is configured in the scan
list. Download the empty configuration to
AH10DNET-5A by using the "Simulate online"
function. Finally, repower it.
If the error still exists after AH CPU and
AH10DNET-5A are repowered, send your
AH10DNET-5A back to the factory for repair.
1. Check if the node address of the slave has

3. Configure the network again.
1. Check the actual IO data length of the slave.
2. Configure relevant slaves to the scanner
1. Check if the node address of the slave has

Check if the slave is operating normally.
Check if the slave is operating normally.
Ensure that the IO data length of the slave is the
same as that configured in the scan list.
Please follow the methods below to shoot the
troubles if the error code appears for long.
1. Ensure that at least two nodes work normally
2. Check if both ends of the network are
