Benefits of technology

"The present patent provides a method for displaying and altering the electrical sequence flow of an automation system. The system includes a plurality of electrical sequence elements, such as steps or transitions, which are connected to each other. The system also includes a user interface for receiving input from a user and displaying the electrical sequence flow on a screen. The user interface can allow the user to identify and change the position of the electrical sequence elements. The technical effect of this patent is to provide a more intuitive and user-friendly way to model and alter the electrical sequence flow of an automation system."

Problems solved by technology

A manual abstraction is time consuming and tends to be error-prone.

Embodiment Construction

[0059]In one aspect of the present disclosure, an improved method of modeling an automation system is provided. Another aspect of the present disclosure is directed to an improved mechanical model of the automation system. Yet another aspect of the present disclosure is directed to an improved mechanical sequence flow of the automation system. Still another aspect of the present disclosure is directed to an improved electrical model of the automation system. A further aspect of the present disclosure is directed to an improved electrical sequence flow of the automation system. Yet a further aspect of the present disclosure is directed to an improved method to monitor an automation system.

[0060]The present disclosure is described in context of the automation system being a lifting apparatus. The principles of the present disclosure, however, are not limited to use within a lifting apparatus but may be applied to other machines and systems in an automation system.

Abstract

The present disclosure describes output signal behavior for a programmable logic controller. The output signal behavior may be modeled in an electrical sequence flow of an automation system. The modeling including a visual representation of the output signal behavior. After the modeling, at least one programmable logic controller of an automation system may be programmed based on the model.

Description

BACKGROUND[0001]In the automation field, and more specifically during operational machine planning for a plant, an engineer traditionally creates a model that describes the operation a machine or system which will later be involved in the plant operation phase. For Example a mechanical model of a lifting apparatus is illustrated in FIGS. 1A-1H.[0002]Referring to FIG. 1A, the lifting apparatus 100 has securing ends 110, rollers 120, a surface 115, and a lifter 130. The securing ends 110 may move up and down and are shown in an up position in FIG. 1A. The lifter 130 may raise or lower the surface 115 and is shown in a lower level position in FIG. 1A. Referring to FIG. 1B, the securing ends 110 are moved down into a down position. Referring now to FIG. 1C, the rollers 120 rotate to convey a parcel 140 onto the surface 115 of the lifting apparatus 100. As shown in FIG. 1D, at a time after the parcel140 is located on the surface 115 of the lifting apparatus 100, the securing ends 110 are...
