License error for recipe and maintenance

[dbindernagel]

Hello,

opening the Gedi produces the following two SEVERE license error messages:

WCCOAui (1), 2022.11.03 17:48:28.703, SYS, SEVERE, 105, Invalid license, No License 'recipe' for the ctrl script, C:\Siemens\Automation\WinCC_OA\3.18\scripts\libs\rcp.ctc
WCCOAui (1), 2022.11.03 17:48:29.021, SYS, SEVERE, 105, Invalid license, No License 'maintenance' for the ctrl script, C:\Siemens\Automation\WinCC_OA\3.18\scripts\libs\wh_sc.ctc

Neither the recipe nor the maintenance feature is used.
How can we get rid of these error messages?

Bug can easily be reproduced by creating a new legacy project and starting it. Once the Gedi is open the error messages appear (of course only when a license is used that is missing these features).

Tested with WinCC 3.18 P013 (but also occurs in previous versions)

Thx

The gedi loads all libs at startup so it knows all functions. So it loads also this rcp.ctc and wh_sc.ctc. If you encrypt CTRL files, you must specify the required "// $License: ", usually this is "NOLICENSE". I guess rcp.ctc has "recipe" and wh_sc.ctc has "maintenance". And that's where this message comes from.

Thank you for the explanation @kilianvp.
I guess I could delete both files but I don't like to mess in the installation folder. Wouldn't survive an update either.

While not really a big problem I would like to avoid to explain to a customer that they are indeed licensed correctly and they should ignore the license error message marked as severe.

Hope ETM finds a workaround for this in the future.

As a workaround you could try adding the following lines to your config file:

Code: Select all

[ui_extend]
UnloadCtrlLibs = "rcp.ctc"
UnloadCtrlLibs = "wh_sc.ctc"

Thank you for the help but this didn't work for me.

The confg entries might not help for the GEDI as this part of WinCC OA tries to load all the libraries.
It looks like the log messages are related to the changes in the licensing system in WinCC OA 3.18. If you want to get further information please get in contact with your common WinCC OA support.
