Abstract: A support device that supports development of a sequence program executed by a control device includes an operation reception module that receives an operation on the support device, and setting module that sets a switching option of a display mode for a call instruction selected from call instructions of a unit program in the sequence program in accordance with the operation received. When the sequence program is displayed, the call instruction is switched to an image of a circuit configuration represented by a sequence logic defined by a corresponding unit program based on the option set and displayed.

Abstract: Provided ts an environment that can effectively supports development of a sequence program. A support device that supports the development of a sequence program deploys, when the sequence program is displayed, a call instruction of a unit program for configuring the sequence program to a circuit represented by a sequence logic defined by the unit program and displays the circuit, and changes, in accordance with an operation of changing the circuit, tire sequence logic of the circuit. When the sequence program is converted into executable code, the support device assigns, to the call instruction in the sequence program, either code of the sequence logic thus changed or code of the call instruction in accordance with a switching option.

Abstract: This information processing device is provided with an editing unit and a storage unit. The editing unit performs editing on one or more controller data sets that contain control programs to be executed on a control device. The storage unit stores a sharing setting table indicative of sharing settings of the control programs included in the respective controller data sets. When the control program for a first controller data set and the control program for a second controller data set that are included in the plurality of controller data sets are set to be shared, the editing unit synchronizes the edited content for the control program for the first controller data set with the control program for the second controller data set.

Abstract: Provided is a development support device that enables a user to easily check and easily edit comments on respective elements or the like of an array type variable. The development support device (10) outputs comments on respective array elements as a data format file which is editable in spreadsheet software, by associating the comments with a name of the array type variable and discrimination information for discriminating between the individual array elements with respect to the array type variable.

Abstract: According to the invention, a ladder diagram program is stored with the data capacity suppressed. A program development supporting part 11 includes a calculation part 111 and a storage part 112. The storage part 112 stores a ladder diagram editing program 21 and a ladder diagram program that has been edited. The calculation part 111 executes the ladder diagram editing program 21 to edit the ladder diagram program and stores the ladder diagram program in the storage part 112. The calculation part 111 assigns two-dimensional coordinates to a ladder diagram represented by the ladder diagram program, detects two-dimensional coordinates and a type of a circuit element included in the ladder diagram and detects two-dimensional coordinates of a vertical connection line included in the ladder diagram, and stores the circuit element and the vertical connection line in association with the two-dimensional coordinates respectively in the storage part 112.
