- the CNC could perform only appropriate processing in response to a request instructed by the host computer and return the result to the host computer again, and could only have a passive role.
- the CNC itself makes appropriate decisions according to the conditions of the surrounding machines and takes necessary measures. It has also been required to instruct the host computer, other programmable controllers, and CNCs. In other words, it has come to be required that CNCs have autonomous functions. Disclosure of the invention
- the present invention has been made in view of such a point, and a net
- the purpose is to give the autonomous function to the CNC as a component of the work.
- a numerical control device which is one component of an FA system, etc., mainly a host computer, a programmable controller that controls the operation of the machine is provided with the status of the machine or other components.
- a numerical control device is provided, which is provided with command means for commanding necessary processing to other components based on the result of monitoring the status of elements.
- Command means are provided in the programmable and controller of the numerical control device, and necessary processing determined based on the result of monitoring the status of the machine or the status of other components is commanded to other components. I did it. For this reason, it is possible to provide the numerical control device with a function of requesting other components for necessary processing. Therefore, it becomes possible to configure an autonomous type numerical control device, which previously could only serve as a server.

- FIG. 3 is a block diagram of the hardware of the numerical controller according to the present invention. BEST MODE FOR CARRYING OUT THE INVENTION
- BEST MODE FOR CARRYING OUT THE INVENTION an embodiment of the present invention will be described with reference to the drawings.
- FIG. 2 is a diagram showing a configuration of an FA system in which the numerical controller according to the present invention is used.
- the FA system 10 is composed of, for example, a LAN.
- the FA computer 1 controls the operation of the CNC systems 2A, 2B, 2C, PLC 3, etc., which are connected to each other by RAN 11.
- Each of the CNCs 2A, 2B, and 2C issues a command to the PLC 3, the FA computer 1, and other CNCs based on the results of its own judgment.
- it is configured as an autonomous CNC.
- the autonomous CNC will be described below.
- FIG. 1 is a diagram showing a configuration of a numerical controller (CNC system) of the present invention.
- CNC system 2A in FIG. 2 will be described as an example, but the other CNC systems are similarly configured.
- the CNC system 2A includes a CNC board 21, a PMC board 22, and a communication board 24.
- it plays a role as a machining cell in the FA system 10 including the machine tool 23.
- These boards 21, 22 and 24 are connected by a bus 20.
- the board 22 receives the request from the FA computer 1 via the LAN 11 and the communication board 24, and performs appropriate processing on the machine tool 23. The processing result is returned to the FA computer 1 via the communication board 24 again.
- the PMC board 22 is provided with a command means 22 A, and the command means 22 A is adapted to the situation of the machine tool 23 based on various data sent from the machine tool 23. Appropriate judgment according to And request the required action from the FA computer 1, PLC 3, and other CNC systems 2B and 2C. It also makes appropriate decisions based on data from other devices other than itself, such as various data on IZ0 devices and the like sent from PLC 3, and similarly takes necessary actions on FA computers. 1 or PLC 3, request for other CNC system.
- the request command is output from the command means 22 A via the communication board 24 and the LAN 11.
- the CNC system 2 A since the command means 22 A is provided in the PMC (programmable controller) 22, the CNC system 2 A itself makes autonomous judgment, and determines an appropriate command. Can be output. That is, the CNC system 2A can be configured as an autonomous CNC, and the functions that the FA computer 1 should originally execute can be executed instead of the programmable controller 22. Therefore, the load on the FA computer 1 is reduced, and the processing speed of the entire system can be accelerated accordingly.
