Config Entries
aliveTimeout
With version 3.17 the config entries "[eip] aliveTimeout", "[mod] aliveTimeout" as well as "[iec61850] aliveTimeout" have been renamed. If they are used within your project they must be replaced with the entries [mod] aliveInterval, [eip] aliveInterval respectively [iec61850] aliveTimeout61850.
Manager Options
Upgrading a project to 3.18 may move some manager options to the corresponding entries in the config file to facilitate the correct usage.
paramLang
If you upgrade a project which contains the config entry "paramLang", you have to delete this entry manually from the config file before starting the project.
Powerconfig
If the powerconfig file is present in the WinCC OA project directory under /config, it has to be merged with the current version from the WinCC OA installation directory under /config.
Scrollbar Config Entries
When upgrading WinCC OA version 3.8 or below to version 3.18, the options for the config entries "vScrollBarMode" and "hScrollBarMode" change their state from "AlwaysOff" to "ScrollBarAsNeeded" due to a change of available options.
Subprojects
When updating a project that contains nonexistent or inaccessible subprojects, these must be commented out in the config file before the project is updated.
