Calling dpDisconnectUserData will crash the process

[flindecke]

When i call dpConnectUserData and afterwards dpDisconnectUserData, a ControlScript Process will crash without notice.

See https://www.winccoa.com/fileadmin/image ... erData.ctl and run it (using CtrlOaUnit).

Expected to see log message "After dpDisconnectUserData"
Actual see logs until message "Before dpDisconnectUserData"

Any tips to solve this problem?

I've started the script to check if a crash occurs. For the test WinCC OA 3.15 + P005 was used.
The manager is stopped in a normal way. A crash cannot be seen.
Some of the last log messages are:
WCCOActrl (2), 2017.08.16 13:52:25.490, SYS, INFO, 1/oaUnit_errors, Testfall 'main' OK, Before dpDisconnectUserData
WCCOActrl (2), 2017.08.16 13:52:25.495, SYS, INFO, 1/oaUnit_errors, Testfall 'main dpDisconnectUserData' OK, dpDisconnectUserData
WCCOActrl (2), 2017.08.16 13:52:25.500, SYS, INFO, 1/oaUnit_errors, Testfall 'main' OK, After dpDisconnectUserData
...
WCCOActrl (2), 2017.08.16 13:52:27.531, SYS, INFO, 2, Manager Stop

Can you please check it again.

Hello Leopold Knipp,

it seems to be a problem of our development version of WinCC OA [hide](a very early 3.16, 2 months old)[/hide].

[spoiler]
We currently need the feature of modfying panel files by CTRL code and writing the panel at runtime to new files.
Also we need the fixed layout problem (with the new panel layout index properties).
[/spoiler]

I will ask our customer service person to get a new version if possible.
Currently it does not crash our application, but a single test fails and crashs the test process.

I will update this ticket when i have more infos.

Thanks for the reply and retest with WinCC OA 3.15 P005.

With regards,
Frank Lindecke
