The invention relates to a method for operating a computer system. The inventive method allows best possible utilization of the efficiency of a concrete target hardware by providing in a program alternative passages of which exactly one is selected for execution by the processor by means of a code.

Method for operating a computer system

In the field of automation technology, processes, which are controlled by stored program controllers (), are divided into modules, which are also known as function blocks. If possible, these function blocks should be used universally. The interfaces of these modules are different from or independent of the technological parameters of the actual technical function. It is a problem for the user to have access to internal knowledge of the program in order to implement the controller () for a specific application. To address this and other problems, a programming tool and programming method for creating programs are disclosed, which will provide the user (), either additionally or alternatively, with technological insight into a process that is to be controlled and/or regulated. An interface () is connected between the user () and the stored program controller (), and a plurality of input masks () is offered to the user () for inputting technological parameters of the process. Therein a respective input mask () is assigned to at least a part of the function blocks.

Programming tool and programming method

A connector for lightwave guides with release levers attached at the narrow sides thereof, which, when lateral pressure is applied, actuate detents. Simultaneously at the narrow sides of the connector casing recesses are provided for the release levers such that the release levers do not rise more than a small amount above the edge of the recess; whereby, the connector can be pulled by manual actuation of the release lever through the recess.

A process and a device for substantially eliminating tolerance-dependent variations of a preselectable space between the components of an optical communication apparatus is described. U-shaped recesses are provided in a metal casing for pressing in flange-type necks of, for example, optical transmitting and receiving devices. The parallel arranged devices are so spaced from each other that they are not subject to tolerance-dependent variations. For this purpose the metallic necks are coated with a plastic layer, and ribs provided at the lateral walls of the U-shaped recesses dig into the plastic layer. The necks are pressed in precisely at a predetermined spacing by means of a gauge. By the application of varying degrees of pressure when the ribs are pressed in on one side and the other side of the neck, one of the U-shaped recesses can be off-center.

Process and apparatus for elimination of tolerance dependent variations

Adjacent lying plug-connector halves, the front ends of which exhibit pin or sleeve shaped plug elements, are provided with first and second supporting bodies, of which the first supporting body, with a sleeve shaped plug element, may be connected by means of a joinable groove-tenon-interconnect lying crosswise to the plug insertion direction, and exhibits an entrance channel for a plug connector half with a pin shaped plug element. The second supporting body with a concentric guiding tube for the insertion of pin shaped plug elements from both directions exhibits a tenon-groove-interlock contour at both ends that matches that of a sleeve shaped plug element. The first supporting body can therefore be interlocked with second supporting bodies or sleeve shaped plug elements at choice, whereby light wave guides single or double plugs may be connected to transmit- and/or receive modules and light wave guides single or double plugs may be inter-connected.
