For the transmission of a telegram from the control device to the peripheral element an intermediate device receives the telegram from the control device and forwards it without amendment to the peripheral element. For the transmission of a telegram from the peripheral element to the control device the intermediate device receives the telegram from the peripheral element and forwards it without amendment to the control device. The telegrams are safety telegrams, so that telegrams forwarded to the control device or to the peripheral element from the respective receiving unit can be checked for freedom from errors.

A method for automatically modifying a program of an automation system, wherein a first item of data related to a program component is determined using an identificator assigned to the automation system, wherein a program code object stored in a database is selected using a selector based upon the first item of data, and wherein the program is modified by means of the program code object in that the program code object is integrated into the program. Further, an automation system with a program having program components and which is automatically modifiable in accordance with the method, having an assigned identificator for determining a first item of data related to a program component, a selector for selecting a program code object stored in a database based upon the first item of data, and an integrator for integrating the program code object into the program and finally a computer readable medium.
摘要:
In one aspect, a method for dynamic configuration of a modular machine, whose modules are interconnected and connected to a control unit via a communications network is provided in order to facilitate the modification of a machine configuration in automated systems. According to the method, during the operation of the machine, one of the communications partners determines the communications partners in the communications network. The communications partner then generates a suitable communications configuration and activates said configuration. This permits the communications configuration or design to be automatically executed, even during the operation of the machine.

Method of operation and control program for a central unit in an automation system, and the central unit in an automation system and the automation system itself. A central unit (e.g., CPU) (1) in an automation system repeatedly executes a control program (8) that is stored in the central unit (1) and comprises at least two subprograms (TP1-TP3). A single instance of execution occurs within a cycle time (T) which is stipulated by the control program (8). The central unit (1) executes only one of the subprograms (TP1-TP3)—the activated subprogram (TP1-TP3)—at a time. The cycle time (T) is independent of the activated subprogram (TP1-TP3), is shorter than the time (t1+ . . . +t8) required in order to execute all of the subprograms (TP1-TP3), and is at least as long as the longest of the times (T1-T3) required in order to execute one of the subprograms (TP1-TP3) once.

The aim of the invention is to improve the configuration of an automation system. To this end, a number of configuration data records are provided in a server connected to a client of an automation system via means of communication, whereby the client and server depict respective automation components. The client to be configured requests one of the number of configuration data records (S1, S5). Afterwards, the server transmits the requested configuration data record (S2, S6). Finally, the transmitted configuration data record is stored and activated in the client. This enables an automatic configuration of a client in an automation system.

The aim of the invention is to provide a method according to which an automation component is automatically integrated into a communication network. For this purpose, the automation component automatically requests a communication address during log-on (S1). A server present in the communication network transmits a corresponding communication address to the requesting automation component or to the client (S2). The inventive method eliminates the need for manually assigning a communication address for an automation component.
摘要:
The present invention is directed to a method of operation and a control program for a central unit (e.g., CPU) in an automation system repeatedly executing a control program that is stored in the central unit and comprises at least two subprograms. A single instance of execution occurs within a cycle time which is stipulated by the control program. The central unit executes only one of the subprograms—the activated subprogram—at a time. The cycle time is independent of the activated subprogram, is shorter than the time required in order to execute all of the subprograms, and is at least as long as the longest time period required in order to execute one of the subprograms once.
摘要:
A method for automatically adopting a configuration of a first automation device on a second automation device includes storing on a removable storage medium a configuration and a unique identifier identifying the first automation device, comparing in the second automation device the stored unique identifier of the first automation device with a corresponding identifier of the second automation device, determining based on the difference between the stored unique identifier and the corresponding identifier of the second automation device whether the storage medium was previously used in a different automation device, and adopting the configuration of the first automation device on the second automation device.
摘要:
An automation system having an automation device for realizing a plurality of automation functions and a control device for controlling the automation device is disclosed. The control device has a plurality of data records with handling instructions for several different types of automation devices. Further, the automation system has a communication network for a communication between the control device and the automation device, the control device being configured to identify connected automation devices in the communication network, to read out the automation functions from the identified automation devices, to identify at least one data record for each identified automation device with the aid of the read-out automation functions, and to initiate each identified automation device for execution of the handling instructions of the at least one identified data record.
