    摘要: An industrial control system device that can be utilized for drive control, process control and/or logic control and which is comprised of a unique combination of hardware and software. Use of one or more of the devices in an industrial control system application permits the control system to be partitioned into subsystems which communicate with one another and which operate as self-contained units. Each subsystem can be further subdivided into modules that have distinct operating functions. The software utilized by the control system device separates the required operating functions of the control system into distinct tasks that operate concurrently (multi-tasking) on a priority level basis while sharing system data and control signals. Three programming languages (BASIC, Control Block, Ladder Logic) are employed so that the most appropriate language can be utilized for each task. Processors can be added to the industrial control system to permit the movement of a task from processor to processor (multi-processing) without reprogramming.

    摘要: A method is provided for configuring a smart module which is coupled to a programmable logic controller. The controller includes an initial configuration file which specifies an initial configuration for the smart module. After power up and initialization of the controller, the initial configuration file is transmitted from the controller to the smart module. The initial configuration file is now designated a current configuration file and the smart module assumes the configuration specified by the current configuration file. In accordance with the method of the invention, module specific information which is stored in the module is then displayed to aid a user in configuring the module. The user can then modify the current configuration file in response to the module specific information which was displayed. This method significantly simplifies the process of configuring smart modules for the user.
