Description

  The present invention provides an alarm display device for notifying the controller status display window and the alarm window of the host device of the operating status information and alarm messages of the modules constituting the controller based on the diagnostic information of the controller communicating with the host device. About.

  FIG. 6 is a functional block diagram showing an example of a conventional alarm display device applied to a distributed control system. Reference numeral 1 denotes a host device, and reference numeral 2 denotes a controller, which communicates with the host device 1 via the network 3.

  In the host device 1, 11 is a controller status display window, and 12 is a controller operating status acquisition means. The controller operating status acquisition means 12 acquires the current operating status information notified from the controller 2 and the alarm presence / absence information for each module constituting the controller, and passes them to the controller status display window 11 for display.

  13 is an alarm window, 14 is a message collecting means, and 15 is an all alarm message holding means. The message collecting unit 14 acquires an alarm message for each module notified from the controller 2, passes it to the alarm window 13 and displays it.

  In the controller 2, 21 is a CPU diagnosis means, 22 is a power supply diagnosis means, and 23 is an IOM (input / output module) diagnosis means, which diagnoses the state of the modules constituting the controller 2 and indicates an abnormal module and abnormality content. Output an alarm message.

  Reference numeral 24 denotes system monitor means, which obtains the operating status information of the module from each of the diagnostic means and sends the current operating status information and the alarm presence / absence information for each module constituting the controller to the controller operating status acquisition means 12 of the host device 1. Notice.

  An alarm management unit 25 collects alarm message outputs of the abnormal modules from the respective diagnosis units and outputs them to the all alarm message holding unit 26 and notifies the message collection unit 14 of the higher level apparatus 1.

  In such a configuration, the controller status display window 11 graphically displays the current operating status of the modules constituting the controller. FIG. 7 shows an example of the display screen. Modules in which an abnormality has occurred are displayed in different colors such as red, and normal modules are displayed in green. In the figure, the hatched PSM (power supply module) and IOM3 modules are displayed in red, indicating that an abnormality has occurred.

  With such a graphical display, the operator can know at a glance the module in which an abnormality has occurred on the controller, but the reason why the abnormality has occurred cannot be determined from this window alone.

  As described above, the controller status display window 11 is not related to the alarm message output by each diagnostic means of the controller. Therefore, when the operator analyzes an abnormality, the alarm window 13 is separately operated to display all alarms. It is necessary to manually extract the alarm message of the corresponding module from the message.

Japanese Patent Laid-Open No. 5-166086

The conventional alarm display device has the following problems in analyzing the abnormality of the module.
(1) The cause of the abnormality is notified to the host device as an alarm message, but the message must be referred to in an alarm window that is not related to the controller status display window. Don't be.
(2) In the case of a one-shot error that occurs immediately after a module error has occurred, the history of the error occurrence cannot be known from the controller status display window alone.
(3) In the graphical display of the controller status display window, alarms cannot be organized and understood for each module (for each card such as a CPU or IOM).

  Therefore, the problem to be solved by the present invention is to provide an alarm display device that can extract and display an alarm message of a module specified in the alarm window by specifying the module from a controller status display window that hierarchically displays the module configuration. Is to realize.

In order to achieve such a problem, the configuration of the present invention is as follows.
