Problems solved by technology

This results in an increase in the number of cycles required to monitor all controllers
[0009] exist Figure 14b In the known example shown in , the monitoring computer activates monitoring tasks (one per controller is required), so these tasks increase in number as the number of controllers connected to the computer increases, causing the monitoring computer to become overloaded

Abstract

A controller management system enables a computer managing a device to effectively communicate with a plurality of controllers. These controllers are connected with the monitoring computer of the management device through the network. The monitoring computer performs power state determination tasks and monitoring tasks. Each controller sends a power-on message indicating the power-on state to the monitoring computer at specified intervals. When the power state monitoring task does not receive any controller's power on information within the specified time period, it is determined that the power supply to the controller is in the off state. The monitoring task skips the controller that has been determined to be powered off, thereby not receiving data from it, and communicates with the next powered-on controller. Since the controller whose power is off is skipped without performing reception data communication with the controller, time for wasteful time-out processing is not required and effective communication can be realized.

Description

technical field [0001] The present invention relates to a controller management system including a plurality of controllers and a management device connected to the controllers through a network for managing the controllers and executing a plurality of applications to perform common processing with the controllers. Background technique [0002] Typically in fields such as production systems, controllers such as CNC (Computer Numerical Controller) or robot controllers that control robots are used to control various machines and equipment. For more efficient production, these controllers are connected via a network to a management device including a computer (personal computer). The management device realizes the management of the controller together with the application software (application program) running therein. Used as a network is a bus-connected network, such as Ethernet (trademark), through which a plurality of controllers are connected. [0003] For example, figu...
