A path information generating device includes: a label information storage unit that stores label information indicating correspondence relations between label names and control devices; a system configuration information storage unit that stores system configuration information indicating correspondence relations between the control devices and networks connected to the control devices; and a path information generating unit that generates path information indicating a path from an access source control device to a first control device based on the system configuration information, and outputs the generated path information. The path information generating unit receives a first label name for designating an access destination, identifies the first control device corresponding to the first label name based on the label information, and sets the first control device as an access destination control device.

Control system and path information generating method

A system construction assistance apparatus includes a first display screen, a second display screen, and a processing section displaying units each belonging to one of categories on the first display screen such that the units are sorted by category, receiving a first input to select one unit from the units displayed on the first display screen, generating a system configuration diagram on the basis of the received first input, and displaying the generated system configuration diagram on the second display screen. After a first input is newly received and before a next first input is received, the processing section predicts a category to which a unit to be selected by the next first input belongs on the basis of first inputs received in a past and presents the predicted category as a candidate category to a user.

System construction assistance apparatus, method, and recording medium

A system construction supporting tool that supports construction of a programmable controller system, the system construction supporting tool including: a product-specification storage unit that stores therein information related to product specifications of units to be used as elements for constructing the programmable controller system; an arranged-unit-information storage unit that stores therein information related to arrangements of units already arranged in an edition operation on a display screen; a unit-list-display control unit that extracts arrangeable units based on the information stored in the arranged-unit-information storage unit and the information stored in the product-specification storage unit; and a unit-list display unit that displays a list of the units extracted by the unit-list-display control unit on the display screen.

System construction supporting tool and system construction supporting device

A shared-label extracting unit extracts a shared label to be associated with a device corresponding to a memory shared by a plurality of control devices. A shared-label write/read information generating unit identifies a control device writing data and a control device reading data with respect to the shared label by referring to a control program, and generates shared-label write/read information. A device batch assigning/associating unit sorts shared labels using the shared-label write/read information, and associates the shared label with an address of the device for each sort based on a result of determining a configuration of the control system.

Programming support apparatus, programming support method, program for causing computer to implement the method, and recording medium containing the program

A connection is made to one of a plurality of programmable controllers (hereinafter, 'PLCs') included in a control system in which the plurality of PLCs are connected to one another via one or more networks; the one of the PLCs is specified as an originating PLC; network configuration information of the control system and online connection paths to the PLCs included in the control system are collected; layout relationships among the networks as well as connection relationships of the PLCs and coordinates thereof are calculated based on the network configuration information and the online connection paths; and the results are displayed on a display means as objects.
