2.4.2CAN bus indicator LED

The i-7540D includes three single-color LED displays to indicate the status of module, network and I/O device. They are ER LED (it is red), TX LED (it is green), and RX LED (it is red). The Indicators assist maintenance personnel in quickly identifying a problem unit. The LED test is to be performed at power–up. When the CAN communication events occur, these indicators will be triggered to glitter with different conditions.

zER LED

This LED provides device status and indicates whether or not the device is operating properly. Table 2-6 shows the conditions of ER status. Therefore, when the device is operated normally, the ER-LED must be turned off. If this led flashing red, users can use the “99S” command, in section 4.5, to read the status of the i-7540D.

 

Table 2-6 ER-LED conditions

Condition

Description

Off

Device is normal; no error occurs

 

 

Red

Device has unrecoverable fault

 

 

Flashing red

Device has recoverable fault.

 

To recover:

 

Reset device or perform error recovery

 

 

zTX LED

This LED indicates the status of message transmitted. Table 2-7 shows the conditions of TX status. Therefore, when the device transmits messages to the CAN bus, the TX-LED is normally flashing green.

 

Table 2-7 TX led conditions

Condition

Description

Off

No data is being transmitted to the CAN side

 

 

Flashing green

Data are transmitting to the CAN side

 

 

Solid green

Transmit data error
