Abstract: A ladder program generating device includes: a ladder chart displayer configured to display a ladder chart including a plurality of program elements; a variable specifier configured to identify one program element included in the ladder chart and specify a variable included in the one program element; a program element searcher configured to search the program element including the variable specified by the variable specifier inside the ladder chart; a search result displayer configured to display a list of program elements searched by the program element searcher as a search result; a search result storage configured to at least store a search history by the program element searcher; and a search result selector configured to select the search result to be displayed next by the search result displayer based on the search history.

Abstract: A time chart creation apparatus for providing control data to a machine control system controlling an operation conversion apparatus includes circuitry which receives an input of a travel distance of a mechanical element of the operation conversion apparatus, receives an input of one or more of an acceleration time, a deceleration time, an acceleration rate and a deceleration rate of the mechanical element of the operation conversion apparatus, calculates a time chart based on the travel distance and one or more of the acceleration time, the deceleration time, the acceleration rate and the deceleration rate such that the time chart includes a velocity transition of the mechanical element of the operation conversion apparatus, and outputs the control data to the machine control system, which controls the mechanical element of the operation conversion apparatus based on the time chart represented in the control data.
