A visual software modeling method based on a software meta view for constructing software meta models. After determining basic components of the software meta view, the present invention constructs software views through the software hierarchy view, the software interface views, the software interaction views, the software algorithm view, the software process view, and the software transfer view as step features and thereby provides a specification for visual software modeling activities in various fields; such specification has advantages including generality and convenience; the software views constructed through the present invention is executable, has a clear structure, adjustable hierarchies, and controllable granularities for modeling; this method supports both top-down analysis and bottom-up integration for modeling in various software modeling; the modeling method is simple and full visual, thereby even those not skilled in any modeling language nor computer programming language can easily and independently construct the software view, eliminating the tedious and unnecessary communication with and dependence on professional modelers and application developers, greatly reducing modeling time.

A method for determining the functional relationship of several pumps which are controllable in their rotational speed, in a hydraulic installation. At least one pump is activated with a changed rotational speed, and at least one functional relationship of the installation is determined from the hydraulic reactions. With a suitable selection of the control and detection of the hydraulic changes, one may determine the functional relationship of the complete installation.

A programming assist device for a PLC program and a programming assist method for a PLC program capable of easily preparing separate executable files for causing redundant CPUs of a PLC to operate and reliably preventing an emergency stop of the PLC due to a failure in converter software are provided. First and second intermediate codes are generated from an original program. An inverse conversion program is generated from the first intermediate code. A reconverted first intermediate code and a reconverted second intermediate code are generated from the inverse conversion program. In the case where the intermediate codes and the reconverted intermediate codes match each other, a first executable file is generated from the reconverted first intermediate code, and a second executable file is generated from the reconverted second intermediate code. The executable files are transferred to the PLC.

The invention relates to a method and system for determining travel paths of painting robots, in particular for the production of electronics. In a hierarchical approach, using mixed integer linear programming (MILP), a surface to be painted is divided into horizontal and vertical regions and strips to be painted, which are then travelled by a painting robot in an advantageous manner.

The method involves providing (S1) data of an area topology, data of a location of an area for a solar cell table arrangement, and data of power plant components e.g. inverters, which are provided for an open area photovoltaic power plant. A configuration of the arrangement of the power plant is provided (S2) based on the provided data for locating the power plant components. The data of the area topology is produced by interpolation of height data by triangulation. Compatibility of the components is tested relative to each other. A number of cable and service paths is calculated. Independent claims are also included for the following: (1) a device for creating a configuration of a solar cell table arrangement for an open area photovoltaic power plant (2) a computer program comprising instructions for performing a method for creating a configuration of a solar cell table arrangement for an open area photovoltaic power plant.

The method is for the control of pump stations and pumps in a pipeline and involves the total energy consumption of all pumps minimised at a predetermined total flow and height. The pipeline has a pump station PS1 with one pump (1), a pump station (PS2) with three pumps (2,3,4) and a pump stastion (PS3) with two pumps (5,6). - The first pump station is in flow direction connected via a pipeline segment (S12) with the second pump station, the second pump station is connected with the third pump station via a pipeline segment (S23) and the first pump station is connected via a pipeline segment (S1) with a first user (V1), which in turn is connected via a further pipeline segment (S2) with a further user (V2). The pump stations generally have several possible different pumps, producing via the users a regular and specific fluid quantity. Control is effected by the adjustment of the speed of the individual pumps and the pressure heights of the individual pump stations to be produced. - An INDEPENDENT CLAIM is also included for a computer program product.
