Summary 

User-LED glows dimly in LED-OFF state


Motivation, trigger 

User-LED glows dimly in LED-OFF state


Details of change

An add-on C-BIOS library or a CODESYS XML import file is available. If

required, please contact STW.


Alert impact

Due to component discontinuation, STW was forced in early 2023 to

use another bi-color LED type with some changed optical

characteristics, esp. the LED chip for red color is some brighter than

it was before.

This results in a dim red glowing, even if the LED is switched off by

software via function x_sys_set_led().

Further, the predefined colors X_SYS_LED_COLOR_ORANGE and

X_SYS_LED_COLOR_YELLOW do not result in the expected color

shade.

Since several years, the market for bi-color LED provides no

alternatives that suit to the ECU requirements.

Unfortunately, there is no hardware solution available for ESX.3xm to

solve this issues.

Software strategy for customers with application programming in C:

STW can provide a small add-on library incl. some xt_sys_led_...()

functions that will avoid the red glowing and will adapt the yellow /

orange color shade. However, this requires an update and

recompilation of existing application software.

This add-on library might be used for all parts with serial number

(T_x_sys_logistic_data.au8_SerialNumber) 230000121713 or higher,

but an appropriate "if-serial-number-above-check" in the application

software is recommended. Please note, that this add-on function

should not be used on parts with serial number below 230000121713

as this would have unwanted impact regarding the color shade.

Software strategy for customers with application programming in

CoDeSys:

STW can provide a XML file that might be imported to CODESYS and

solves the "shifted color shading" issue by changed scaling of

ou16_Color via new FB_xtSysLedSet (instead of original

FB_x_sys_set_led) or via new "I/O Mapping"

FB_xtSysLedColorRemap. This routines also ensure a correct

handling of old vs. new LED type (by checking if ECU serial number

lower/higher than SerN 230000121713). However, there is no solution

available in CODESYS for the "dim red glowing".
