In online mode, the Status tab of the bus coupler provides monitoring and diagnostics information for the bus coupler and connected modules.
Displaying Diagnostic Information
Bus coupler and expansion module status information is displayed under the Status tab of the bus coupler in EcoStruxure Machine Expert.
For more information, refer to Status tabs description.
The following graphic shows the LEDs of TM3 Modbus Serial Line bus coupler:
The following table describes the status LEDs:
|
LED |
Color |
Status |
Description |
|---|---|---|---|
|
PWR |
Green |
On |
Power is applied. |
|
Off |
Power is removed. All LED indicators are off. |
||
|
COM |
Green |
Flashing |
Data sending and receiving. |
|
Off |
No data exchanged. |
||
|
Red |
Flashing |
Device is receiving an incorrect data frame. |
|
|
ERR |
Red |
Flashing |
Device has detected an error that is, under most circumstances, recoverable. For example: oRotary switch position changed during operational mode. Return to the initial position to reset the LED behavior. oError detected during firmware update. oCommunication and configuration errors. |
|
Off |
No error detected. |
||
|
I/O |
Green |
Flashing |
Device has received and applied the expansion modules configuration. |
|
On |
Device is communicating with the expansion modules. |
||
|
Green Red |
Flashing On |
The physical configuration is inconsistent with the software configuration. No data exchange (status and I/O) is occurring. |
|
|
Green Red |
On On |
The physical configuration is inconsistent with the software configuration. I/O data is not applied. |
|
|
Green Red |
On Flashing |
At least one TM2 or TM3 expansion module did not respond to the bus coupler for 10 consecutive cycles. |
|
|
Off |
No configuration. Device is not communicating with the expansion modules. |
NOTE: With the exception of the PWR LED, each LED is ON for a few seconds, then OFF during boot sequence. The LED behavior rules apply when the boot is completed successfully.
