What is a Project?

A project (or application as it is sometimes known) is the configuration that is required to customize the operation of PcVue for a particular use. A typical project will include mimics, variables, communications, data recording, user configuration and programs.

You can create a new project or select an existing one using a dialog displayed by the Select Project command on the Configure.Project sub-menu. ClosedShow picture

How to create a new project

  1. From the Project sub-menu, display the Select Project dialog.
  2. Type the name of the new project into the text field at the bottom of the dialog. See below for limitations that apply to project names.
  3. Select the OK command button. PcVue will create the new project.
  4. Shut down and restart PcVue. You can then select the new project for opening.

How to select an existing project

  1. From the Project sub-menu, display the Select Project dialog.
  2. Select the name of the project by double clicking on its name in the list of projects.
  3. Select the OK command button.

The project folder structure

Each project appears as a sub-folder under the project root folder, USR. Normally the project root appears under the PcVue root folder although, using the -b option in the command line that starts PcVue, it can be located elsewhere. ClosedShow picture
