Description

  The present invention relates to a system design support apparatus, method, and program for supporting design of a monitoring system.

  In the FA (Factory Automation) field, a monitoring system is used to monitor industrial machines. Examples of the components of the monitoring system include a control device that controls the industrial machine, a network connected to the control device, a server connected to the network, and a monitoring device connected to the server and monitoring the control device.

  The control device is exemplified by a programmable controller (JIS B 3502: 2011, programmable controllers (PLC)). The network is exemplified by Ethernet (registered trademark) or CC-Link. The server is exemplified by an OPC (OLE for Process Control) server. The monitoring device is exemplified by a SCADA (Supervisory Control And Data Acquisition) device.

  As a related technique, the following Patent Document 1 describes one processing system of a real-time operating system in order to manage the ratio of the execution time of the application scheduler and the ratio of the execution time of data processing to one execution cycle time of the system. And a determination means for determining and notifying whether or not the execution time of the data processing is sufficiently secured when the execution time of the bandwidth management layer is set by the user (Claim 1).

  Patent Document 2 below stores a blinking interval time management table storing command / response response times of each PLC, and displays the display icon of each PLC in the network configuration diagram as the previous command / response response time. There is described a network configuration diagram display device that blinks in response (paragraph 0031 to paragraph 0035).

  Further, in the following Patent Document 3, in the plant monitoring control system, when the signal transmission route for the selected signal is not limited to one, the designer does not perform an operation to limit the signal transmission route to one, A database construction method is described in which a signal transmission route is automatically determined based on the load of each passing device in order to equalize the load on the passing device and network (paragraph 0044).

  Further, the network configuration diagram display device described in Patent Document 2 blinks the display icons of the PLCs in the network configuration diagram according to the previous command / response response time. Therefore, the network configuration diagram display device described in Patent Document 2 is configured so that the display icon of each PLC in the network configuration diagram is displayed according to the previous command / response response time unless the system is actually constructed and operated. Cannot blink.

  In addition, the database construction method described in Patent Document 3 automatically determines a signal transmission route based on the load of each passing device in order to equalize the load of the passing device and network. That is, in the database construction method described in Patent Document 3, a plant monitoring control system is constructed, and thereafter a signal transmission route is automatically determined. Therefore, the database construction method described in Patent Document 3 may cause a trouble that the target monitoring performance is not achieved after the plant monitoring control system is actually constructed.

  The present invention has been made in view of the above, and an object of the present invention is to obtain a system design support apparatus capable of suppressing a trouble that a target monitoring performance does not appear after an actual monitoring system is constructed. .

The line 14e1a of the network improvement plan data 14e1 describes “Change Ethernet (registered trademark) to CC-Link”. In general, the communication time interval of the network CC-Link is shorter than that of the network Ethernet (registered trademark). Therefore, when the network is a bottleneck, the network monitoring performance can be improved by changing Ethernet (registered trademark) to CC-Link.

  In the line 14e1b of the network improvement plan data 14e1, “divide the network” is described. Dividing one network into two networks reduces the load on each of the networks.

  In the line 14e2b of the monitoring device improvement plan data 14e2, “reducing the number of monitoring data” is described. When the number of monitoring data is reduced, the load on the monitoring device is reduced. Therefore, when the monitoring device is a bottleneck, the monitoring performance of the monitoring device can be improved by reducing the number of monitoring data.

  In the row 14e2c of the monitoring device improvement plan data 14e2, “2 units” is described. When the number of monitoring devices is two, the load on each of the monitoring devices is reduced. Therefore, when the monitoring device is a bottleneck, the monitoring performance of the monitoring device can be improved by using two monitoring devices.

  The server improvement plan data 14e3 also describes an improvement plan for improving the monitoring performance of the server when the server is a bottleneck, like the network improvement plan data 14e1 and the monitoring device improvement plan data 14e2.

  Similarly to the network improvement plan data 14e1 and the monitoring device improvement plan data 14e2, the control device improvement plan data 14e4 describes an improvement plan for improving the monitoring performance of the control device when the control device is a bottleneck.

  Referring to FIG. 2 again, the CPU 11 executes the system design support program stored in the storage unit 14. Thus, the system design support unit 11a is realized.
