Definitions
- the invention relates to a method for exchanging field device data.
- field devices are often used to regulate or control process sequences.
- level meters which determine the level of a liquid in a liquid container.
- Pressure gauge which measures the pressure of a liquid or a gas e.g. B. determine in a pipeline.
- Mass flow meters that determine the mass flow of a liquid in a pipe section.
- Valves that regulate the flow in a pipe section.
- Such field devices are normally connected to a central control unit via a data connection line, which controls the entire process sequence in a manufacturing plant.
- field devices are complex technical devices that are normally tested by the manufacturer before delivery, but which are nevertheless due to the special application conditions (temperature, pressure, chemical properties of the process liquid or process gas etc.) and the complex interaction with them other field devices and special data communication can only function to a limited extent. If the user has problems with his or her special process application, he usually contacts the customer or service department of the manufacturer.
- the customer or service department takes up the problem and usually offers the user various solutions or sends a service technician.
- the Internet offers a global exchange of data and information in a worldwide network.
- Data (files) on so-called servers can easily be transferred from other computers (Clients) can be accessed and downloaded via download.
- This data can be linked on servers in such a way that new files are created for clients that can be further processed.
- This technology is already used by Internet search engines (Yahoo, Altavista, Hotbot, etc.) or is used in e-business. Such Internet search engines are very complex and their data must be updated regularly. In some cases, links that are displayed in a hit list are no longer available.
- the object of the invention is therefore to make current data available via field devices to a large number of users without this data having to be temporarily stored or updated on an additional storage medium.
- This object is achieved by a method for exchanging field device data, in which several computer units connected to the Internet form a user group and each user releases special files on his computer unit for access by other users, one computer unit being temporarily selectable as a client and the rest Computer units serve as a server, characterized in that the client sends a search request to a relay server connected to the Internet, which forwards the search request to the server and the servers compare the released files with the search request and report the corresponding hit file to the relay server if they match creates a hit list from all hit files and sends this hit list to the client.
- the essential idea of the invention is that several users, for example using field devices from a certain manufacturer, form a user group that make certain files (information) on their computer units available to the other users and that these files can be searched via the Internet.
- the search query is from
- Relay server forwarded to the corresponding computing units.
- the relay server creates a hit list from the hit files, which is sent to the client.
- the client can select a special file from the hit list and download it from the corresponding server.
- the Internet is only used for data transmission. No search engines are needed for the search, the information of which must be updated regularly. The information is only available to the user in a file. If the user updates this file, the updated information is immediately available to the entire user group.
- the single drawing shows several computer units R1, R2, R3, R4, which are connected to one another via the Internet (world wide web WWW).
- the number of computing units is not limited to four, it can be any.
- the data is transmitted on the Internet WWW using the known standards TCP / IP and is not the subject of
- Each computer unit R1, R2, R3, R4 has a screen BS1, BS2, BS3, BS4 for displaying information.
- the computer units R1, R2, R3, R4 form a user group.
- each computer unit R1, R2, R3, R4 several files are normally stored on a storage medium.
- Special files FD which contain information about field devices, are released by the user for the user group.
- This information can e.g. deal in problem solving, device descriptions, documentation etc.
- users need a software program SW, which they e.g. can load and execute them on diskette in their computer units.
- This software program SW can e.g. B. be provided by the manufacturer of the field devices.
- the search query consists of one or more search terms that can be linked together (Boolean logic).
- This computer unit R1 temporarily represents the client.
- the software program SW sends the search request to one or more relay servers RS1, RS2, RS3.
- the relay servers RS1, RS2, RS3 forward the search request to the other computer units R2, R3, R4 of the user group.
- a list of the computer units R1, R2, R3, R4 belonging to the user group is stored in the relay servers RS1, RS2, RS3.
- Each computing unit R2, R3, R4 checks its released files FD for compliance with the search request. If there is a match, the computer unit R2 sends the name (s) of the hit file (s) found to the relay server (s) RS1, RS2, RS3.
- the relay server (s) RS1, RS2, RS3 compile a hit list from the hit files and send this to the client R1.
- the hit list is displayed on the client R1 screen.
- the client R1 can now select a file from the hit list and download it from the relevant computer unit, for. B. Download R2.
- the relay servers RS1, RS2, RS3 can also be dispensed with.
- a similar process is already offered by the Gnutella company via the Gnutella.com website.
- each computing unit has a list of the computing units belonging to the user group. However, this list need not be exhaustive.
- a client directs a search query to a computer unit known to it, the user lists are compared and the query is directed to all computer units that appear at least once. In this way, all computer units of a user group are successively reached using a kind of snowball system.
