Abstract

The invention relates to a method for controlledly carrying out a measure on a hydraulic device (1), in particular a hydraulic valve, having a hydraulic unit (1a), a control unit (1b) and a data-storage unit (1c), by a user, wherein the control unit (1b) of the hydraulic device (1) is connected to a computing unit (3) via a connector (2). In the method, which is being performed by the computing unit (3), the type of the hydraulic device (1) is first determined (S100) on the basis of identification data stored in the data-storage unit (1c) of the hydraulic device. Subsequently, on the basis of the measure and the type of the hydraulic device (1) that has been determined, at least one action is ascertained (S110) that has to be performed in order to carry out the measure. Information regarding the at least one action is displayed (S120) on a display of an I/O device (4) which is connected to the computing unit (3). The computing unit (3) determines (S130) whether the at least one action has been performed, and, if it is determined that the at least one action has been performed, a result of the action is determined (S140). Subsequently, it is determined (S150), on the basis of the result of the at least one action that has been performed, whether at least one further action has to be performed and, if it is determined that no further action is required to carry out the measure, the result of the actions performed is stored (S160) in the data-storage unit (1c). The invention also relates to a system for performing the method.

Description

Method and system for carrying out an action on a hydraulic device Description The present invention relates to a method and a system for carrying out a measure on a hydraulic device. Background of the invention Existing software programs with user interfaces for interacting with hydraulic devices may have the ability to read and write parameters. However, the user interfaces and operating logic or workflows differ depending on the product or product family. At the moment, service technicians have to describe parameters directly using various software and use the operating instructions to find out which parameters they need. Although there are some dialogs in the existing software solutions for the various product families and products, these are not uniform and vary depending on the product. The user must therefore not only be familiar with the different products or product families, but also with the different user interfaces and operating logic. Depending on which function is required, the user must jump into the submenus and parameters must be adjusted manually. This complex structure means that users must know in advance what the exact goal is and which steps must be taken to achieve this goal. Manual calculations must be carried out, for example to determine setpoint values. There may be no user interface at all for individual parameters or groups of parameters. These must be looked up in the function or operating instructions and manually described using the parameter search. Users must be very familiar with a range of products in order to be able to provide good service using various software programs. disclosure of the invention According to the invention, a method and a system for carrying out a measure on a hydraulic device with the features of the independent patent claims are proposed. Advantageous embodiments are the subject of the subclaims and the following description. The invention is based on a hydraulic device, in particular a hydraulic valve, which has a hydraulic unit, a control unit that controls the hydraulic unit, and a data storage unit and on which a measure, for example commissioning, maintenance and repair work, troubleshooting or a conversion measure, is to be carried out by a user. For this purpose, the control unit of the hydraulic device is connected to a computing unit, for example an external server, via a data-transmitting connector (so-called connector, e.g. commercially available industrial PC). The method according to the invention, which is carried out by the computing unit, enables the user to carry out services on different products and product families using workflows with instructions, without having to resort to different systems that require different user interfaces and operating logic. The workflows make it easier for the user to achieve their goals through intuitive use. A workflow is a sequence of steps that must be carried out in a specific order. There can be nodes at which, depending on the answer or input, a branch to further steps occurs. This means that there is a workflow logic that allows context- and product-dependent decisions to be made. It contains several components that combine various backend services with a frontend. First, a type of hydraulic device is determined based on identification data stored in the data storage unit of the hydraulic device. It is also possible that further data, such as specified parameters, which are also stored in the data storage unit, are stored by the computing unit and/or the parameters of the hydraulic unit are reset. The data stored in the data storage unit The identification data stored can be displayed in particular on the display of an input and output device connected to the computing unit, so that the user can compare them with the identification data printed on the hydraulic device and correct them if necessary. Based on the measure that can be communicated to the computing unit by the user via the input and output device and the specific type of hydraulic device, at least one action is determined that must be carried out to carry out the measure. The actions can in particular be one or more of a measuring process, a reading process from the data storage unit, a writing process to the data storage unit, a calibration of the hydraulic device and a control of the hydraulic device. Information about the at least one action, i.e. a workflow for carrying out the measure, is then displayed to the user on the display of the input and output device. Depending on the action to be carried out, this is carried out by the computing unit, the user or a combination of both. In the next step, it is determined whether at least one action has been carried out. This can be determined automatically by the computing unit, for example, or the user can confirm the completion of an action via the input and output device. If it has been determined that at least one action has been carried out, a result of the at least one act
