Abstract

In order to be able, for control of an automation system, to project, establish, process and/or simulate device functions of the control devices used in a simple and flexible way, the invention provides a method by means of which at least one software module is made available in an execution environment (350) with a program function (301-305b, 311-315, 321a-324) that can be executed in the execution environment (350), where the program function (301-305b, 311-315, 321a-324) is a representative function of the device function (201-205b, 211-215) that is stored in an associated control device (101-105, 121-125) of the control system, the device function and the program function are at least partially identical, the device function comprises at least one first variable function parameter, and the program function comprises at least one second variable function parameter that is assigned to the first function parameter of the device function, the second function parameter is adjusted as a function of user inputs, the adapted second function parameter is transferred to the associated control device (101-105, 121-125) via a network (400), and the first function parameter is set at the value of the second function parameter. Furthermore, the invention provides a control device and control system that are designed to carry out the method.

Dependent claims

A method for controlling an automation system, wherein a control system with control devices with predetermined device functions that are interconnected via a network is used for the control, and wherein a control program with a predetermined device function is stored in at least one control device, the method comprising:

providing an execution environment that is connected to the network,
providing at least one software module within the execution environment with a program function that is executable in the execution environment, wherein:
(i) the device function comprises at least one first variable function parameter,
(ii) the program function is at least one of a revolutions per minute (RPM) regulator and a speedometer function, and
(iii) the program function comprises at least one second variable function parameter that is assigned to the first function parameter of the device function;
adapting the second function parameter as a function of user inputs, wherein the user inputs are made available by a user interface of the execution environment;
transmitting the adapted second function parameter from the execution environment to the at least one control device via a network;
setting the first function parameter to the value of the second function parameter,
wherein the program function is a representative function of the device function stored in the control device, and wherein the device function and the program function are at least partially identical,
wherein the representative function is assigned to the device function, and
wherein a part of the device function is shifted to the representative function, in such a way that the device function is carried out partially in the device and partially within the execution environment by the corresponding representative function, so that the device function is completed by the representative function, and
controlling the automation system using the control device and the representative function.

9 more elements

A control device of a control system for controlling an automation system, comprising:

a memory with a first program module stored in the memory, wherein the first program module comprises at least one executable device function with at least one first variable function parameter,
a processor unit for executing the first program module, and
a network interface for connecting the control device to a network,
wherein the first program module is designed to communicate via a software interface with at least one second program module,
wherein the second program module is arranged in a computer system that is connected to the control device via the network and that comprises at least one program function with at least one second variable function parameter,
wherein the program function is at least one of a revolutions per minute (RPM) regulator and a speedometer function,
wherein the program function is a representative function of the device function stored in the control device, and wherein the device function and the program function are at least partially identical,
wherein the representative function is assigned to the device function, and
wherein part of the device function is shifted to the representative function, in such a way that the device function is carried out partially in the device and partially within the execution environment by the corresponding representative function, so that the device function is completed by the representative function, and
wherein the automation system is controlled using the control device and the representative function.
