摘要:
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.
摘要:
A controller managing system that enables a computer of a managing device to efficiently perform communication processing with a plurality of controllers. These controllers are connected via a network. to the monitoring computer of the managing device. The monitoring computer performs a power status determination task and a monitoring task. Each controller transmits power-ON information representing a power ON state to the monitoring computer at prescribed intervals. When the power status determination task cannot receive the power-ON information within a predetermined time period from either one of the controllers, it is determined that the power supply to that controller is OFF. The monitoring task skips the controller that is determined as being in a power OFF state; so as not to receive data therefrom, and communicates with the next controller that is in a power ON state. Since the controller whose power is OFF is skipped so as not to perform data reception communication therewith, time for wasteful timeout processing is unnecessary and efficient communication can be achieved.
摘要:
A controller and a display device are connected to each other by a network. The controller comprises a network control program which controls a network control section to communicate with the display device for each of a plurality of operation modes, including an initialization mode, a normal action mode, and an alarm mode. Various data, such as operation mode information for the controller, are transmitted to the display device connected by the network through the network control section and display data is displayed on the display device.
