WAGO-I/O-SYSTEM 750 CoDeSys 2.3 Runtime Environment 133758-874/000-131 WAGO-I/O-IPC-C6ManualVersion 1.0.011.10.4 Frequently Asked Questions About CoDeSys WebVisualizationHow can I optimize the applet for special screen resolutions?In order to optimize the Web visualization for a PDA or a touch panel with a fixedresolution, you should proceed as follows:In the "Target system settings", enter the pixel width and height in the tab"Visualization". When the visualization is created, the visible area is highlightedin grey. However, the actual pixel width and height of the Web visualization isdefined by the attributes "Height" and "Width" of the HTML APPLET tag in the"webvisu.htm" file. Do not forget to also adapt these parameters to the existingresolution.Which JRE should I use?It is recommended that you use Java2 standard edition Version 1.5.0(J2SE1.5.0_06) or higher. This is available free of charge at www.sun.com.Microsoft's MSJVM3810 was also tested. Furthermore, for PDAs there areruntime environments available from other manufacturers (JamaicaVM, CrEme,etc.). To be considered is that for the Web visualization, these solutions canbehave differently with respect to their scope of services (e.g. stability) than thosementioned above.Should the Java Cache be used?Neither yes nor no. After a standard installation the cache is enabled. If the cacheis enabled, the JRE uses it to store applets and Java archives. If the Webvisualization is called up a second time, it requires considerably less time to startbecause the applet (approx. 250 kb) does not need to be reloaded via the network,but is already available in the cache. This is especially interesting when networkconnections are slow.Note:The Java archives may not be transferred into the cache completely due tonetwork failures. In this case, the cache must be cleared manually or be disabled.
