2.2 LED Indication
The GW-7433D provides three LEDs to indicate what situation is in the
GW-7433D. They are described as follows.
2.2.1 Power LED
The GW-7433D needs +10 ~ +30 V
The Power LED will be turn on after applying power and it will be flashing one
time per second.
2.2.2 Module Status indicator LED
The GW-7433D includes three single-color LED displays to indicate the
status of module, network and I/O device. They are MI LED (it is red), CI LED
(it is green), and ERR LED (it is red). The indicators assist maintenance
personnel in quickly identifying a problem unit. When the GW-7433D events
occur, these indicators will be triggered to glitter with different conditions.
MI LED
The LED indicates the Modbus communication status of the GW-7433D.
Following shows the condition of MI status. When GW-7433D is working and
has received a Modbus message, the MI LED will be flash red.
○ LED off: The GW-7433D receives no Modbus command.
○ LED on: The GW-7433D is receiving a Modbus command.
CI LED
This LED indicates the CANopen communication status of the module.
Following shows the conditions of CI status. When module is online and start
to communicate with the devices, it will flash. If there are no TxPDO, RxPDO,
TxSDO, RxSDO protocol running, then the CI LED will be turn off.
○ LED off: The GW-7433D receives no CANopen message.
○ LED on: The GW-7433D is receiving a CANopen message.
ERR LED & ERROR Message show in 7-LED
This LED indicates the CANopen status of the GW-7433D. The
following description shows the conditions of error status.
○ LED off: The GW-7433D has no error.
○ LED flash: The GW-7433D gets some communication errors.
○ LED on: GW-7433D gets some configuration errors.
Note: The table 2-6, section 3.4, and 4.2.2 have more information about
the details of error messages.
