Re: Commit and checkout a WinCC OA project in SVN

If you have a central development server where you can run WinCC OA you can use the following setup: -- Start the main WinCC OA project on the server -- On the UI clients only start a UI manager which connects to the server, e.g. with config entries or start parameters If data in the database is cha...

Re: Commit and checkout a WinCC OA project in SVN

Leopold, if I understand it correctly, you propose that, before commiting a project, I (or whoever makes a modification) have to export to an ASCII file all the contents of the project, commit it, and, after a checkout I have to import that ASCII file in my project? Is this export/import done via t...

Re: Question about AES print / printTable()

When using WinCC OA 3.17 the function printTable() has a new optional parameters "options" with a mapping. The mapping can have a key "fitToWidth" which possibly has the effect that the column width is changed automatically to fit the text. I did not test, I just had a look at the documentation. In ...

Re: RAIMA Database Error *** Code:-6

Only with this part of the log messages we cannot see possible causes for the problem. Probably there are more log message written which refer to the problem in the database. If you need more information please get in contact with your common WinCC OA support. Please be aware that you have to stop a...

Re: Redundancy - Both servers active

For the Video server I do not know how redundancy and the connection check works in detail as it is a 3rd party software. If you want to have you can possibly ask the software vendor for the video software or get in contact with your common WinCC OA support. Best Regards Leopold Knipp Senior Support...

Re: Configure TCP-server

As described in my previous post you have to add some config entries for the driver connecting only to server 2.
The entries are necessary to give the driver the information that the "_2" datapoints must be used.

Re: Configure TCP-server

Are you starting the IEC driver which connect to server 1 and server 2 on the same machine? Why aren't you starting only one driver which connects to both servers? If you want to start a remote driver which connects only to server 2 in a redundant system you have to add additional config entries to ...

Re: Problems with 'copyFile'

With the CTRL function access() you can check the access mode for a file or directory.
Possibly you can use this function to detect if a write permission is given before calling copyFile().

Re: Cache for Desktop-UI transforms some folders to xx.gz files

I have made test with 3.17, in 3.16 the behaviour is possibly the same. When files are transferred to the Desktop-UI they are compressed as gz files. The compression is only made for files but not for folders. With the debug flag "-dbg http" for the script webclient_http.ctl you can possibly get add...

Re: Generate an alert when driver connection is down

Yes, I am talking about the elements where the "connection state" is written to. The name of the DP element may differ for every driver. You can modify the internal datapoints and add an _alert_hdl config to it. The System Overview panel can be used to configure an error state and an _alert_hdl conf...
