Explanation
Error Codes and LED Indicators for Module AS01DNET
(RTU Mode)
Indication
Node ID of the scanner module
(When in RUN state)
The node ID is repeated or
exceeds allowed range.
No I/O module is configured to
AS01DNET (RTU) in the
DeviceNet Builder software.
The work voltage of AS01DNET
(RTU) is too low.
AS01DNET (RTU) enters the
test mode.
AS01DNET (RTU) is the Bus-
Off state.
2. Check if the baud rate of AS01DNET-A is the same as that of
other node in the network.
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.
If the code is displayed long, do the troubleshooting according to the
following steps.
1. Make sure that at least two nodes work normally in the network.
2. Check if either end of the network is connected with the terminal
resistor of 121Ω.
3. Check if the baud rates of the node devices in the network are
same.
4. Check if the communication cable is normal so as to avoid that
the cable is disconnected or connected loosely.
5. Check if the bus cable length exceeds the maximum transmission
distance. If so, the system may not be stable.
6. Check if the shielded wire of the network cable is grounded.
7. Re-power AS01DNET-A scanner module.
No correction needed
1. Ensure that the node ID of AS01DNET (RTU) is unique in
the DeviceNet network within the range of 0~63.
2. Repower it on after changing the node ID.
Add I/O modules in AS01DNET (RTU) in the DeviceNet
Builder software and download the configuration data to
AS01DNET (RTU) after the configuration is finished.
Check if the power supply for AS01DNET (RTU) works
normally.
Repower AS01DNET (RTU).
1. Check if the network communication cable is normal and
the shielded cable is grounded.
2. Ensure the baud rates of all network nodes are same.
3. Check if the two ends of the network are both connected
with a 120Ω terminal resistor.
4. Repower the scanner module.
