12.4.9 Error Codes and LED Indicators for Module AS01DNET
(Master/Slave Mode)
Code Explanation
Node address of AS01DNET-A
0~63
(in normal operation)
80 AS01DNET-A is in STOP status.
The node ID of AS01DNET is the
F0 same as that of other node or
exceeds the allowed range.
F1 No configured slave in Scan List.
Too low voltage of the work
F2
power
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.

Turn the PLC to RUN and start I/O data exchange
1. Ensure that the node address of AS01DNET is unique.
2. Re-power AS01DNET.
Configure the scan list and then download the configuration to
AS01DNET.
Check if the power supply for AS01DNET and the PLC is normal.
Switch the function switch IN1 from On to Off and re-power
AS01DNET-A.
1. Check if the network cable is normal and the shielded cable is
grounded.
2. Check if the baud rates of all nodes in the network are same.
3. Check if the start and end of the network cable are both connected
with a 121Ω terminal resistor.
4. Re-power AS01DNET-A.
1. Check if the network cable is normal.
2. Ensure that the network power is normal.
If the error still exists after re-power, send AS01DNET-A back to the
factory for repair.
If the error still exists after re-power, send AS01DNET-A back to the
factory for repair.
If the error still exists after re-power, send AS01DNET-A back to the
factory for repair.
1. Configure the network correctly and re-download it to AS01DNET-
A.
2. Check if the node address of one slave in the scan list is the same
as that of AS01DNET-A.
1. Check if there is any change in node ID of the slave in the
network.
2. Check if some node device in the network is replaced.
3. Re-configure the network.
Re-configure I/O data size of the slave, download the configuration to
AS01DNET-A and run the PLC.
1. Check if there is a change in the node address of the slave.
2. Check if the communication cable is disconnected or connected
loosely.
3. Check if the bus cable length exceeds the maximum transmission
distance. If so, the system may not be stable.
1. Make sure that the connection between AS01DNET-A and the
network is normal.
