A sequence-program design support device includes a display unit displaying a work screen corresponding to a designing work, an input unit receiving a setting operation of work phases, a zoom-in operation, and a zoom-out operation, a state storage unit storing the work phases and a current work, a work-model storage unit storing a partial order relation of a work specified for each of the work phases with a work screen corresponding to the work, and a control unit displaying a work screen corresponding to a next work of the current work in the order relation and storing the next work when the input unit receives the zoom-in operation with a first operation amount, and displaying a work screen corresponding to a previous work of the current work in the order relation and storing the previous work when the input unit receives the zoom-out operation with a second operation amount.

A ladder display device of the disclosure includes: a ladder circuit storage unit that stores an insertion condition including at least an operation start position of a gesture operation, an operation end position of the gesture operation, and a circuit state of a net on a ladder diagram related to the gesture operation as insertion target ladder circuit information in association with a ladder circuit that is an insertion target; a ladder circuit condition determination unit that, with reference to the ladder circuit storage unit, determines a ladder circuit whose insertion condition is satisfied by a gesture operation performed on the touch panel; a ladder circuit generation unit that generates a ladder circuit determined by the ladder circuit condition determination unit as the gesture operation satisfying an insertion condition; and an edition control unit that inserts a ladder circuit generated by the ladder circuit generation unit into the ladder program.

A technology for associating and ascertaining the location of device variables which are in a control program and correspond to devices, and the dependency relations between the device variables, when division programming is carried out, is provided. A graph display device according to one aspect of the present invention generates a first directed graph, which comprises a plurality of first nodes respectively representing the device variables, and edges representing the existence of a dependency relation, and a second directed graph, which comprises a plurality of regions corresponding respectively to each subprogram, a plurality of first nodes, and edges, wherein the first nodes are arranged in a region of a subprogram that uses the device variable to be expressed from among the plurality of regions. In response to an instruction from a user the display device switches between displaying the generated first directed graph and displaying the generated second directed graph.

Various systems and methods are presented regarding monitoring and controlling operation of a process. A visual representation of the process can be created based on a supermodel comprising models (representing one or more devices) and nodes (representing respective device variables and constraints). Further, the process can be represented by levels, wherein devices at each level can be self-aware and have onboard artificial intelligence, such that a device at any level can auto-configure itself in accordance with a requirement placed upon it. Field-level devices (IFLDs) can be smart devices which auto-configure based upon a requirement from a higher-level device. Accordingly, system awareness can be incorporated across all levels of the process enabling overall and device-specific optimization of the process. IFLDs can auto-configure to collect and transmit data in accordance with an instruction from a higher-level device, leading to efficient data collection, reduced data bandwidth/processing, and expedited system optimization.
