PLC DESIGNING APPARATUS

摘要

An editor-screen display unit configured to cause a display device to display a list of one or more units applicable to a programmable logic controller, a unit-configuration display unit configured to cause the display device to display a model indicating an arrangement state of the one or more units of the programmable logic controller, a unit-selection/arrangement-input detecting unit configured to detect unit selection operation for selecting a unit in the unit list using an input device and unit arrangement operation for designating a CPU unit on the model by operating the input device in a state in which the unit selection operation is maintained, and a management-CPU-determination processing unit configured to determine a CPU that manages the unit selected by the unit selection operation as a CPU included in the CPU unit designated by the unit arrangement operation, are included.

1. A PLC designing apparatus formed on a computer including a pointing device and a display device by the computer executing an editor program and configured to design a programmable logic controller having a multi CPU configuration including a plurality of CPU units, the PLC designing apparatus comprising:
an editor-screen display unit configured to cause the display device to display a list of one or more units applicable to the programmable logic controller; a unit-configuration display unit configured to cause the display device to display a model indicating an arrangement state of the one ore more units of the programmable logic controller; a unit-selection/arrangement-input detecting unit configured to detect unit selection operation for selecting a unit in the unit list using the pointing device and unit arrangement operation for designating a CPU unit on the model by operating the pointing device in a state in which the unit selection operation is maintained; and a management-CPU-determination processing unit configured to determine a CPU that manages the unit selected by the unit selection operation as a CPU included in the CPU unit designated by the unit arrangement operation.
