Have you seen this post Refresh delay? Basically if pictures are slow to open the first thing you should do is determine WHY. Usually the delay can be eliminated. In the rare cases where it is not possible to speed up the opening time ( due to PLC or network delays or amount of scripts on a PDL ) it is possible to load all windows into PictureWindows and simply make them visible / invisible. This will slow down the initial start-up time for WinCC Runtime but after that the PDLs are opened automatically. This is because they are already open and just being made visible ! Remember, when a PDL is opened, all scripts on the picture are run. This is usually what causes the delay along with poorly configured update rates. |

Yep, cyclic triggers will usually cause slow picture loading times. Please change all these scripts to use a tag trigger (where possible) and let us know if it helps. NOTE : Use the User Cycle 1 for the poll rate of the tag trigger. This means you are polling the tag every User Cycle 1 (e.g. 1 second) and not running the script every User Cycle 1. This distiction makes all the difference with performance [;)] Attachmentperformance.zip (445 Downloads) |
