Embodiment Construction

[0018] figure 1 A detailed circuit diagram of subassembly SK1 is shown. In this embodiment, the structural component SK1 comprises three standard components T_ON, BSEL and AND interconnected for specific functions. Each component has at least one input and one output. In this exemplary embodiment, the inputs IN and TIME of the component T_ON are connected to the connectors IN and TIME. Accordingly, the input IN2 of the component BSEL is connected to the connector IN2. The connector arranged on the left side of the figure represents the input interface of the structural component SK1. Interaction with other program parts is adjusted through these interfaces. Connectors OUT and OUT1 of the output interface are provided on the right side of the figure. They are connected to corresponding outputs of the components AND and BSEL. In this case, the structural component SK1 with the described structure is defined as a type A structural component. When the type of structural com...

Abstract

According to the invention, during the continuous operation of an automation system, one type of structural component is initially modified by means of a projection tool in the surroundings of the projection, independently of the start of operation of the structural component and a characteristic of the type is maintained in a constant manner. Subsequently, the instance the structural component is replaced in the function plan by the modified structural component and the structural modifications are correspondingly recorded. In the following step, the exchanged structural component is transmitted into the automation system, parallel to the continuous operation of the automation system and without repercussions thereon. In said automation system, the uninterrupted switching to the configuration takes into account the exchanged structural component such that the modified and exchanged structural component is activated.

Description

technical field [0001] The invention relates to a method for exchanging structural components for an automation system. Background technique [0002] The automation of large plants, such as power plant plants, requires flexible and versatile control technology and automation systems in order to handle increasingly complex control and regulation tasks. [0003] Changes or adaptations to current conditions in control technology systems are implemented by design. Graphical design tools are mainly used here at present. Changes implemented in the design environment in the control technology system can be carried out in the operating environment of an automation system arranged at a lower level, which is formed from a plurality of memory-programmable control devices. [0004] In the European standard EN 61131-3, also known as IEC 61131-3 or IEC 1131-3, five programming languages ​​are defined with which memory-programmable control devices can be programmed. An example of a full...
