GEDI

With 3.18 the list of illegal characters for data point names has been updated.

Forbidden characters for data point names are: blank and . : , ; * ? [ ] { } $ @ as well as unprintable ASCII characters:

\x01 \x02 \x03 \x04 \x05 \x06 \x07 \x08 \x09 
\x0A \x0B \x0C \x0D \x0E \x0F 
\x10 \x11 \x12 \x13 \x14 \x15 \x16 \x17 \x18 \x19 
\x1A \x1B \x1C \x1D \x1E \x1F 
\x20 \x7F

See here for more information on these unprintable characters.

Since WinCC OA 3.14 the font sizes are saved in pixels instead of points. This means a possible change in the font size for panels from older projects.

From Version 3.18 onwards, the behaviour of the pattern search in the GEDI search window pattern was changed. Instead of the previous search with patternMatch(), patterns are now made with perl compatible regular expressions. Thus it works similar to regexpIndex().

Starting with 3.18, objects which are managed by layouts can not be moved or resized. This includes script actions as position, positionAsDyn, size or sizeAsDyn.

Due to enhancements to the WinCC OA Layout Management feature the existing behavior and default values have changed. Consider this when upgrading your WinCC OA project. It may be necessary to adjust your existing layout settings to get the previous visuals representation of your panels.

With version 3.20, the behavior of dragging and dropping a picture from the project tree into a free area of ​​the panel changes. Previously, this set the background of the panel. Now a new rectangle (without frame, in the standard size of the picture) is created with the picture as "fill".
