  FIG. 11 is a flowchart of a calculation process performed when the programmable logic controller configuration calculation unit of the programmable logic controller setting file generation support apparatus according to the first embodiment calculates a programmable logic controller setting file candidate. In the calculation process of step S110, the following steps S111 to S115 are executed in order.

  In step S111, the programmable logic controller configuration calculation unit 38 acquires the device score upper limit 74 of the record of the programmable logic controller 13 selected in step S100 shown in FIG. 5 and registered in the specification information 70 of the programmable logic controller. .

  In step S112, the programmable logic controller configuration calculation unit 38 acquires the connectable number 93 of the network 15 selected in step S100 shown in FIG.

  Thereafter, steps S113 to S115 are loop processing, and the processing is repeated for the number of input control devices.

  In step S114, the programmable logic controller configuration calculation unit 38 adds the value of the device score upper limit 84 necessary for control to the cumulative value during the loop processing.

In step S115, the programmable logic controller configuration calculation unit 38, the network 15 which connects the control device 14 and a programmable logic controller 13 that is the target of loop processing, network indicating the cumulative value of the control devices on the network Add 1 to the number of connected units.

  FIG. 12 is a flowchart illustrating a flow of determination processing in which the programmable logic controller configuration calculation unit of the programmable logic controller setting file generation support device according to the first embodiment calculates a programmable logic controller setting file candidate.

  In the determination process in step S120, the necessity of reconfiguration of the programmable logic controller configuration is determined based on the result of the calculation process in step S110. In the determination process of step S120, the following steps S121 to S130 are executed.

  In step S121, the programmable logic controller configuration calculation unit 38 compares the number of connectable networks 93 with the number of network connections calculated in step S115, and determines whether the number of network connections exceeds the connectable number 93. To do.

  In step S122, the programmable logic controller configuration calculation unit 38 compares the device upper limit score 74 of the programmable logic controller 13 with the device score calculated in step S114, and determines whether the device score exceeds the device upper limit score 74.

  FIG. 13 is a flowchart of a process flow in which the programmable logic controller configuration calculation unit of the programmable logic controller setting file generation support device according to the first embodiment reconstructs the programmable logic controller configuration. In the reconstruction process in step S130, the following steps S131 to S134 are executed in order. Steps S133 and S134 are a loop process, and the process is repeated by the value calculated in step S131.

  In the programmable logic controller setting file generation support device according to the first embodiment, it is assumed that there is no correlation between the device score upper limit 74 usable by the programmable logic controller and the network connectable number 93. For this reason, the flowchart shown in FIG. 13 corresponds to the reconstruction of the programmable logic controller configuration for both the upper limit 74 of devices that can be managed by the programmable logic controller that causes the reconstruction of the programmable logic controller configuration and the network connectable number 93. To do.

  In step S131, the programmable logic controller configuration calculation unit 38 calculates the number of groups that need to be divided by dividing the total calculated value by the upper limit value. The calculated value here is the total of the set device scores or the total of the networks 15 selected by each control device. As described above, the change method 104 has three types of “upper limit”, “equal”, and “replacement”. If the change method is an upper limit, the upper limit value is a value defined in the default value 105 of the programmable logic controller configuration calculation rule 100, that is, the upper limit 74 of device points or the network connectable number 93. If the change method is equal, the upper limit value is a value defined in the set value 106 of the programmable logic controller configuration calculation rule 100. If the change method is replacement, the upper limit is 1.

  In step S132, the programmable logic controller configuration calculation unit 38 defines a threshold value for the next loop processing. The threshold value is an index indicating how many control devices are included in one group. This index is determined by the change method 104. If the change method 104 is an upper limit, the threshold value is a value defined as the default value 105 of the programmable logic controller configuration calculation rule 100, that is, the upper limit 74 of device points or the network connectable number 93. When the change method 104 is equal, a value obtained by dividing the total number of device points by the value calculated in step S131 is set as a threshold value. When the change method 104 is replacement, the device value upper limit 74 or the network connectable number 93 is set as a threshold value after replacement with another programmable logic controller 13 or network 15 that can include the calculated value sum.

  Thereafter, step S133 and step S134 for distributing each control device 14 to each programmable logic controller 13 or network 15 are repeated.

  In step S133, the programmable logic controller configuration calculation unit 38 adds the values to be calculated and calculates a cumulative value. The value to be calculated is a device score for a device and 1 for a network.

  In step S134, when the cumulative value of the calculation target values exceeds the threshold value, the programmable logic controller configuration calculation unit 38 sets a set of control devices up to immediately before as a control target of the same programmable logic controller or network.

  In the display process of step S140, the programmable logic controller configuration candidate display unit 36 receives a programmable logic controller configuration that satisfies the restrictions of the device score upper limit 74 and the connectable number 93 from the programmable logic controller configuration calculation unit 38, and displays it on the display device 21. Let The programmable logic controller configuration calculation unit 38 selects the network 15 so that the programmable logic controller 13 and the control device 14 are connected by the network 15 of the type 92 that matches the types set in the network type 75 and the network type 85. . Further, when there are a plurality of programmable logic controllers 13 or networks 15 applicable to the programmable logic controller configuration, the constraint conditions set by the user are satisfied based on the power consumption 76, 86 and the prices 77, 87, 94. The programmable logic controller 13, the control device 14, and the network 15 are selected.

  The constraint conditions are conditions when the programmable logic controller configuration calculation unit 38 selects a programmable logic controller, a control device, and a network to be applied to programmable logic controller configuration candidates. Specific examples of constraints include price and power consumption. In other words, when a price constraint is set, the programmable logic controller configuration calculation unit 38 selects a programmable logic controller, a control device, and a network to be used for the programmable logic controller configuration so as to be within the set price. To do.
