Abstract: A method for splitting and merging runtime software for a programmable logic controller, wherein the runtime software is splittable between a plurality of programmable logic controllers. After the runtime software has been split, the runtime software of a programmable logic controller may be merged into the runtime software of a different programmable logic controller.

Abstract: The present disclosure provides a dynamic view in a modeling of an automation system. A first portion of the model may be described in a first sequence description and a second portion of the model may be described in a second sequence description. The sequence descriptions are linked together. In one embodiment, the links are visually provided.

Abstract: The present disclosure describes the insertion of proxy steps in a model of on automation system. A location is identified to insert the proxy step. The proxy step is inserted at the location. In one aspect an icon is displayed where a proxy step may be inserted, in which case the icon is replaced by the proxy step. A programmable logic controller may be programmed based on the model.

Abstract: A visualization of an electrical machine operation model of logic controller behavior is displayed on a display such as a two-dimensional computer display. The display includes separate spaces representing separate devices in the model. For each device, several characteristics are shown in the model, including mechanical steps, electrical steps and electrical signal outputs. The electrical steps are shown superimposed on the mechanical steps, and electrical transitions link sequential electrical steps in time. Representations of conditions link the electrical transitions with signal outputs upon which the electrical transitions are conditioned.

Abstract: An electrical logic controller behavior model of logic controller behavior is automatically or semi-automatically derived from a model of mechanical machine operation. To create the electrical model, an electrical step is created corresponding to each mechanical step of the mechanical model. For each mechanical transition on the mechanical step, a corresponding electrical transition is created on the corresponding electrical step. For each identified signal associated with an end position of the mechanical step, a condition is created for the associated signal on the corresponding electrical transition. The electrical logic controller behavior model is then used to generate PLC-specific software to control a machine or plant.
