摘要:
Modular production machines with appliances and components, controlled by means of projects. A project is the establishment of an arrangement of appliances and modules. A plurality of machine objects is associated with the determined arrangement locations in the project. In this way, the projects have a variability in terms of different machine objects, which is enabled by an engineering system. A control system (a run-time system) can affect a corresponding selection from the options. To enable an economical control of production machines some appliances or components can be selectively replaced by other appliances or modules.

A method of displaying building system controller data includes receiving a user login associated with predefined user access privileges and receiving a building system controller selection, requesting a listing of building system controller applications and activities from a building system controller associated with the building system controller selection, and generating a display of available building system controller applications and allowable activities based on the user access privileges and based on the listing.

A method and system for allocating programming objects of a control program configured to control a distributed control system having a plurality of distributed control modules. A graph model of the distributed control system is constructed which represents all the possible allocations of the control program's virtual programming objects to the processing resources associated with the system's control modules. A maximum matching algorithm is applied to the graph model to determine an optimum allocation, which, for instance, may be the allocation that provides the maximum benefit. The system and method also provide for intervention by the user to refine or "tune" the allocation process. Further, the system and method provide for iteratively solving the graph matching problem, thus reducing the computation time for allocating the programming objects of a complex distributed control system
摘要:
A highly distributed industrial control system employs a number of separate control modules communicating together on a shared communications medium. Each module emulates one or more basic electrical parts having electrical terminals, such as switches and relays, and transmits production messages indicating the state of the parts, such as conducting current or not. A connection list for each part in each control module defines message identifiers of other parts whose production messages are received by the control module and interpreted as current flow to one or more of its parts. The control system is programmed by generating a schematic on a programming terminal showing connections of terminals on symbols of the parts such as would represent actual wiring of the emulated parts. A parts layout diagram is used in conjunction with the schematic to identify each part to a physical module. In this way the program is divided to run concurrently on the various modules without explicit instructions by the programmer.

A connection list for each part in each control module defines message identifiers of other parts whose production messages are received by the control module and interpreted as current flow to one or more of its parts. The control system is programmed by generating a schematic on a programming terminal showing connections of terminals on symbols of the parts such as would represent actual wiring of the emulated parts. This schematic is analyzed to determine the immediate upstream neighbors of each part and the message identifiers of those parts in the control modules form the connection lists. In this way the program is divided to run concurrently on the various modules.
摘要:
The present disclosure is generally directed to automation systems and methods of use thereof to control devices. More particularly, the present disclosure includes systems including function-based controls and methods of assigning function-based controls to allow a user to add, relocate, and/or remove a device without requiring the user to reprogram the system.
摘要:
The invention relates to a method for parameterizing operating means connected to a data transmission medium. In this case, for at least several of the connected operating means, in each case, a device description will be stored in a central facility, each device description containing at least one function and the parameter set belonging thereto. In addition, a list of several predefined device functions will be stored in memory, for which the corresponding parameter set will be assigned each time to the operating means that support the device function. If a device function is selected, then in response to the selected device function, at least one operating means that supports this device function will be parameterized.

摘要:
A control system with a plurality of devices connected through a network may be started up by connecting a control system setting device including a computer accessible to profile data which describe characteristics of these devices and to program parts for programs executed by these devices. The profile data are prepared individually for the devices, and at least some of them include program part data that specify program parts for at least some of the devices. A memory device stores a control system setting program for creating programs executable by at least some of the devices. This control system setting program serves to input network data related to connection relationships of the devices on the network, to extract program part data from the profile data related to an object device for programming on the network based on the network data, to display on a display device those of program parts that are utilizable by the object device for programming based on the extracted program part data, to have a user to select program parts to be used, and to create the program by using these selected program parts.
摘要:
A cell for a network which provides for sensing of conditions, communicating messages and controlling objects through messages encoded into segments of six bit codes each containing 3 binary ones and 3 binary zeros. The messages begin with one predetermined code which provides bit synchronization followed by a second predetermined code which provides byte synchronization.
