Use Ethernet Communication instead of USB.So little modification on several sections could cause long time to build. Incremental build online: Not too big number of changes at a time: when a modification is done on a section, this complete section is rebuilt.Use Build change instead of Rebuild All (Off line).Use if possible periodic Task, with enough extra time (20% of the current scan time) to treat on line modification.On LL984 language, reduce the number of networks per segment, recommended: 40 to 100 networks maximum by segment.use small sections wherever possible in order to facilitate program maintenance and optimize performance when performing online modifications (as all the section content is downloaded during On line Change).To give you an indication, the size of a section should be limited by the application structure to around 300 instructions.General-> PLC diagnostics: turn off application diagnostics, if possible (Off line+On line) If needed : Use the HMI Variable only, to reduce the number of variables. Only use this if you need it for your SCADA system or Vijeo Designer HMI. Data dictionary-> uncheck if not needed (On line) will reduce the amount of MB being sent by reducing the information on variables.Select: Auto upload - on user request (On line) (1) (if Upload information have been check, if not this option is not applicable).Uncheck "Upload information" if you need to be secure completly keep this option.
Check "Optimize data online" change (On line).Uncheck: "save STA" (On line) if you need to be completly secure keep this option.General-> Project autosaving on download (On line) General->Management of Build messages: Turn off any warnings you don’t need (Off line + On line) Following advices will reduce time to build application (off line, on line or both).
