The following figure explains the EEC initialization process:

The main application of EEC is ec.exe, which is located in the EEC installation folder. The main program does not contain any program logic. It ensures the Windows-compliant calling of Eclipse (exe file, display of the application icon when switching with ALT-Tab, etc.).

The ec.exe file starts the Java Virtual Machine (VM) via the program javaw.exe.

The ec.exe file transfers the VM arguments, which are called VMArgs. On the one hand, VMArgs control the VM’s behavior, for example, the maximum RAM. On the other hand, arguments can be transferred to the VM that are interpreted by the application running in the VM (in this case, the EEC).

Eclipse underlying the EEC defines the Eclipse arguments, which control ec.exe, for example, for enabling or disabling the Welcome screen, but which are largely transferred to the VM during the booting of the platform.

Eclipse arguments and VMArgs are transferred to ec.exe for initialization. The effects of the VMArgs placed on the running application can be checked in the running EEC:

  1. Click Help > About EPLAN Engineering Configuration > Installation Details > Configuration.

The transfer of the Eclipse arguments and VMArgs to ec.exe is based on the default Eclipse mechanisms. Two mechanisms are supported for the specification of the parameters:

  1. Transfer via batch file.
  2. Initialization file (ec.ini).
