Abstract: 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.
