How Can I Increase the Memory Limit Available for EcoStruxure Machine Expert on 32-Bit Operating Systems?
Large EcoStruxure Machine Expert projects can stress a 32-bit operating system to the technical limit regarding memory consumption. This is due to 32-bit operating systems providing only 2 GB of memory for user processes such as EcoStruxure Machine Expert.
Identifying a Large EcoStruxure Machine Expert Project
EcoStruxure Machine Expert projects can be considered to be large if they contain a large total count of Objects. The Objects that are available in a project, such as Devices, POUs, Actions, DUTs, Global Variable Lists, Visualizations are listed in the Statistics tab of the Project Information dialog box. However, it is not just the total count of Objects that can indicate a large project. Even individual Objects can be inherently large.
