The Operating System The Operating System Software Before a computer can perform any work it must boot and make active special software known as an operating system. The eV+ operating system coordinates the activities of all the computer components and any external equipment used by the system. When you first turn on the Omron Adept controller, this software is automatically loaded and made ready for use. You do not have to do anything special to make this software active. For details on customizing and optimizing the operating system behavior, see Customizing an Omron Adept System, which lists several options for customizing and optimizing the operating system behavior.
However, as delivered from Omron Adept, the operating system will correctly run your basic system. Application Software Application software makes the Omron Adept system perform the tasks required by your particular automation system. Application software has many sources: Omron Adept provides standard graphical interface and optional application packages; Omron Adept system integrators provide custom software programs; or you may create your own application software. Application software must be specifically loaded from the Secure Digital card to system RAM each time the controller is turned on, or after each time the programs are removed to make room in RAM to run other programs.
For details on loading and unloading the software, see Understanding eV+ Programs. 1 Omron Adept's "Assembly and Information Management" system. The Operating System The eV+ operating system manages the flow of information within the controller. The operating system accepts instructions from application programs, input from workcell peripheral devices, and operator input from the pendant. The tasks performed by the operating system include:
l Managing the execution of application programs l Managing the flow of information to and from mass storage devices l Monitoring external devices attached to the controller l Reporting errors generated during processing In general, unless you are programming applications, you do not have to be concerned with the internal operation of the operating system. Using Files and Directories Application programs and other data are stored in files on the system storage device (Secure Digital card, or USB device) when not being actively used by the controller.
