Abstract
A PLC system includes a displacement sensor, drives, and a PLC. The PLC system performs a data obtaining process for obtaining one-dimensional information from the displacement sensor and positional information from the drives in a task with a first constant cycle, and performs a data generation process for generating two-dimensional shape data or three-dimensional shape data based on the obtained measurement data in a task with a second constant cycle, and can set an amount of processing to be performed for one task in the data generation process.
Claims19
A control system, comprising:
- a measurement device configured to obtain one-dimensional information about an object,
- a drive configured to change a relative position of the measurement device relative to the object, and
- a controller configured to control the measurement device and the drive to obtain information about a two-dimensional shape or a three-dimensional shape of the object based on the one-dimensional information obtained by the measurement device,
- the controller including
- a measurement data obtaining unit configured to perform a data obtaining process for obtaining the one-dimensional information from the measurement device and positional information from the drive in a task with a first constant cycle to obtain measurement data through the data obtaining process, and
- a shape data generation unit configured to perform a data generation process for generating two-dimensional shape data or three-dimensional shape data based on the measurement data obtained by the measurement data obtaining unit in a task with a second constant cycle,
- wherein the shape data generation unit is configured to set an amount of processing to be performed for one task.
A control method used by a controller for controlling a measurement device configured to obtain one-dimensional information about an object, and a drive configured to change a relative position of the measurement device relative to the object to obtain information about a two-dimensional shape or a three-dimensional shape of the object based on the one-dimensional information obtained by the measurement device, the method comprising:
- performing a data obtaining process for obtaining the one-dimensional information from the measurement device and positional information from the drive in a task with a first constant cycle to obtain measurement data through the data obtaining process;
- and
- performing a data generation process for generating two-dimensional shape data or three-dimensional shape data based on the measurement data in a task with a second constant cycle,
- wherein performing the data generation process includes setting an amount of processing to be performed for one task.
A non-transitory computer-readable recording medium storing a program for a controller that controls a measurement device configured to obtain one-dimensional information about an object, and a drive configured to change a relative position of the measurement device relative to the object to obtain information about a two-dimensional shape or a three-dimensional shape of the object based on the one-dimensional information obtained by the measurement device, the program causing a processor included in the controller to perform operations comprising:
- performing a data obtaining process for obtaining the one-dimensional information from the measurement device and positional information from the drive in a task with a first constant cycle to obtain measurement data through the data obtaining process;
- and
- performing a data generation process for generating two-dimensional shape data or three-dimensional shape data based on the measurement data in a task with a second constant cycle,
- wherein performing the data generation process includes setting an amount of processing to be performed for one task.
