F3 AS01DNET enters the test mode
F4 BUS-OFF
F5 No network power
Internal error; Flash or RAM
F6
check error
Error produced in factory
F8
manufacturing
Internal error; EEPROM access
F9
failure
FA Invalid configuration data
Identification parameters returned
E0 from the slave do not match the
configuration data.
I/O Data size returned does not
E1
match that in the scan list.
The slave device in the scan list
does not exist or is offline when
AS01DNET-A is in master mode.
E2
The I/O connection between the
slave AS01DNET-A and the
master is broken when
AS01DNET-A is in slave mode.
AS01DNET-A fails to transmit
E3
data.
Error detected in sequence of
E4 fragmented I/O data from the
slave device.
The slave device returns error
E5 when AS01DNET-A attempts to
communicate with it.
IO data size returned from the
E6 slave is bigger than that
configured in Scan List.
AS01DNET-A is checking MAC
E7
ID.
Explanation
Switch the function switch IN1 from On to Off and re-power
AS01DNET-A.

Check if the slave is operating normally.
Check if the slave is operating normally.
Check that the IO data size of the slave should be the same as that
configured in Scan List.

Correction
Check if the network cable is normal and the shielded cable is
grounded.
Check if the baud rates of all nodes in the network are same.
Check if the start and end of the network cable are both connected
with a 121Ω terminal resistor.
Re-power AS01DNET-A.
Check if the network cable is normal.
Ensure that the network power is normal.
Configure the network correctly and re-download it to AS01DNET-
A.
Check if the node address of one slave in the scan list is the same
as that of AS01DNET-A.
Check if there is any change in node ID of the slave in the
network.
Check if some node device in the network is replaced.
Re-configure the network.
Check if there is a change in the node address of the slave.
Check if the communication cable is disconnected or connected
loosely.
Check if the bus cable length exceeds the maximum transmission
distance. If so, the system may not be stable.
Make sure that the connection between AS01DNET-A and the
network is normal.
Check if the baud rate of AS01DNET-A is the same as that of
other node in the network.
