Abstract: A robot simulation apparatus for moving a virtual robot along a track includes: a track calculating unit that performs, in an interrupt time interval, track calculation processing for calculating a track of the virtual robot after a sampling time; and a time changing unit that separately sets both of the sampling time and the interrupt time interval variable in a range in which the sampling time is equal to or shorter than the interrupt time interval.

Abstract: A control system configured to control a predetermined unit by using a control program running on a general-purpose OS. The control system includes an auxiliary storage device configured to store the general-purpose OS, the control program, and various data items required for the control program to run, and a main storage device on which each of the general-purpose OS and the control program are loaded when they are executed. The entire auxiliary storage device is constituted by a silicon disk, or by a hard disk and the silicon disk.

Abstract: A multi-tasking system in which tasks are grouped and the action of the safety function is different for each group so that the control of a machine can safely and easily be performed with one control device and that the monitoring of each device can be performed at all times, and a medium and a processing device in which a program thereof is recorded. A multi-tasking system 100 for controlling a plurality of tasks has a program executing unit 11 for processing a plurality of tasks by the multi-tasking processing and a task table 21 for keeping grouping information set for each of the plurality of tasks, and the program executing unit 11 has stop units (an emergency stop unit 16, a temporary stop unit 17 as the safety function, and the stop unit obtains grouping information from the task table 21 on the basis of a stop instruction and identifies a group of each task, and performs a different control for each group.

Abstract: A database, in which information an NC apparatus needs in machining products is accumulated for each product, is set in a hard disk connected to the NC apparatus. In this database, products are represented by numbers assigned to them. When an operator specifies a product number, information required for machining of the product corresponding to that number is retrieved and extracted from the database to be automatically transferred to a predetermined memory of the NC apparatus.
