The controller includes a program storage that stores programs specifying a plurality of operations associated with at least one operable unit; a program executor that executes the programs; an operation executor that causes the operable unit to operate according to the programs; and an operable unit manager that manages control of the programs. When a program is called from one of the programs, the operable unit manager obtains control of a group associated with the operable unit and specified in the called program, and releases control of a group other than the group associated with the operable unit and specified in the called program.

A total time necessary for work is shortened by reducing program correcting. A control device has a teaching program storage storing a teaching program, a command interpreter transmitting a movement-related command to a movement-related command separator, determining whether the command is a synchronous interval command or an asynchronous interval command and separating the movement-related command into command of each device according to a determination result, and executing a non-movement-related command, a movement-related command buffer selecting one of the transmission of the movement-related command to the sub-locus calculator and accumulating movement-related command therein based on a device movement state, a main locus calculator calculating movement information on the device on which synchronous control is performed from the movement-related command, a sub-locus calculator calculating movement information on the device that is not a synchronous control target based on the movement-related command, and a motor driver performing operations of the devices.

A robot controller used in a system having a machine tool and a robot, by which the robot is properly operated corresponding to an operation state of the machine tool. The robot controller has a data communicating part which obtains data representing an operation state of the machine tool at predetermined timing; a motion pattern storing part which stores a plurality of motion patterns of the robot for the machine tool; and a motion controlling part which selects a motion pattern from the stored plurality of motion patterns when an abnormality occurs in the machine tool or when an operation state of the machine tool satisfies a predefined condition, and operates the robot based on the selected motion pattern, the selected pattern being associated with an operation state of the machine tool when an abnormality occurs or when the operation state satisfies the predefined condition.

A numerical control system 1 comprises a numerical control device 5 for generating a machine tool command signal and a robot command signal, and a robot control device 6 for controlling the operation of a robot 3 on the basis of the robot command signal. The numerical control device 5 includes a coordinate form information management unit 524 for managing coordinate information according to a designated coordinate format that is based on a numerical control program, and a robot command signal generation unit 525 for generating the robot command signal on the basis of said coordinate information and a robot numerical control program. The robot control device 6 acquires a coordinate value on each axis of control in the designated coordinate format when the designated coordinate format is configured or changed, and transmits the same to the numerical control device 5 The coordinate form information management unit 524 updates said coordinate information using the coordinate value transmitted from the robot control device 6.

The control system includes a first controller, a second controller, and a third controller. The third controller includes a first communication module, a second communication module, and a control processing module configured to output a first operation command for operating the first controlled object to the first controller via the first communication module, configured to output a second operation command for operating the second controlled object to the second controller via the second communication module, configured to acquire information on a current position of the first controlled object from the first controller via the first communication module, and configured to correct the second operation command on a basis of information on the current position of the first controlled object.
