Modules have three LEDs on the front upper right edge. Depending on the error or operational procedure that occurs, the LEDs will flash in certain sequences providing the user a code to either diagnose the problem or be aware of module status.
LED codes for module status
-
Blue LED indicates the module status
-
Green LED indicates the communication bus status
-
Q.series XE: EtherCAT bus status (INIT | PRE_OP | SAVE_OP | OP)
-
Q.series XL: Localbus status (configuration | run | timeout)
-
-
Red/green LED indicates the analog input status
-
Green: analog input is configured and no range error
-
Red: analog input is configured, but a range error
-
When a configuration file is downloaded via Localbus the red/green LED flashes to show that the download is active.
LED codes for problem diagnoses
When a hardware or configuration failure has been detected the blue and the red/green LEDs signal the failure code.
APP failure codes
A problem with the module's application program is indicated by the following flashing sequence of the blue LED: flash 1x - break - flash 1x.
The flashing sequence of the red LED indicates the failure:
|
Flash 1x - Break - Flash 1x |
Incorrect calibration file |
|
Flash 2x - Break - Flash 2x |
Incorrect FPGA code |
|
Flash 3x - Break - Flash 3x |
DIP switch access failure (timeout) |
|
Flash 4x - Break - Flash 4x |
Socket EEPROM access failure (timeout) |
|
SOS (blue and red LED) |
A mismatch between the configuration file in socket EEPROM and module EEPROM. |
OS failure codes
A problem with the module's operating system is indicated by the following flashing sequence of the blue LED: flash 2x - break - flash 2x.
The flashing sequence of the red LED indicates the failure:
|
Flash 1x - Break - Flash 1x |
Incorrect calibration file |
|
Flash 2x - Break - Flash 2x |
Incorrect FPGA code |
|
Flash 3x - Break - Flash 3x |
Application (APP) cannot be read |
|
Flash 4x - Break - Flash 4x |
FPGA cannot be found |
|
Flash 5x - Break - Flash 5x |
Calibration file codes are not accepted for this module |
|
Flash 6x - Break - Flash 6x |
ET1100 configuration file cannot be read |
|
Flash 7x - Break - Flash 7x |
DDR access or reset failure |
Q.series XE-specific LED codes
- Green LED: EtherCAT bus status (INIT | PRE_OP | SAVE_OP | OP)
-
Blue LED:
-
Configuration mode: 5 s ON, 500 ms OFF, 5 s ON, 500 ms OFF, …
-
After a GetlifeList command, the module can be configured differently through the RS485 interface. The GetLifeList is only possible when the module is in PRE_OP or INIT state. Then a file can be downloaded and the module can be reconfigured.
