Definitions

  • the invention relates to a web server with software modules integrated in the web server and an automation system or a computer program product with such a web server.
  • web servers that are connected to clients via the Internet and make this information, usually Internet pages, available are called web servers.
  • Such a web server is an application that runs on one or more computers. Data is stored centrally on the web server, which can be used by many different clients, regardless of the respective location of a client. Both the software application running on a computer and the computer itself are referred to as web servers.
  • web servers serve as a universal provider of information on the Internet, but also in local networks that are based on Internet technologies.
  • the option of expansion modules of the web server is often used, e.g. to enable access to databases, forms, etc.
  • US 6 061 603 A describes a control system which enables a user to achieve a programmable logic controller via a communication network, such as the Internet, using a web browser.
  • the system contains an interface between the network and the programmable logic controller.

  • the object of the invention is to demonstrate a non-proprietary solution for realizing an automation functionality.
  • This object is achieved with a web server with software modules, in which at least one first software module has first means for realizing an automation functionality and second means for accessing a real-time operating system.
  • the invention is based on the knowledge that the classic world of automation today has few points of contact with the Internet, since automation technology mainly uses proprietary protocols.
  • the web server according to the invention surprisingly combines web technology with automation technology, in that an expansion module integrated directly into the web server, usually a software module, provides the required automation functionality.
  • a web server expanded in this way in terms of functionality can handle both complex tasks of classic automation technology and smaller tasks, for example in the consumer area.
  • the direct integration of the automation functionality into the web server means that existing web implementations can also be used when processing the automation task.
  • the web server has a real-time operating system.
  • the automation components used must be real-time capable, especially when used in process automation (e.g. drive control in paper production). This requirement is met by coupling the first software module to the real-time operating system.
  • the real-time operating system can be used in addition to a non-real-time capable operating system (in part) or as the sole operating system.
  • the web server according to the invention By connecting the web server according to the invention to a communication network, in particular the Internet, on the one hand Internet technologies of automation technology are accessible and on the other hand a continuous connection of the automation components to the communication network or the Internet is achieved.
  • Internet protocols for communication of the software modules with one another and for communication of the software modules with components outside the web server enables the components of the web server to be standardized with regard to their communication interfaces.
  • the expansion of the web server with additional modules is made easier, since these can be used without complex adaptation to proprietary protocols.
  • Examples of common Internet protocols are HTTP and FTP (File Transfer Protocol).
  • the web server is provided for the configuration and administration of the software modules.
  • the web server according to the invention is easily scalable and can therefore be used according to a further advantageous embodiment to control the components of an industrial automation system if the first software module has a connection to the industrial automation system.
  • the web server In order to use available Internet security mechanisms, it is proposed that the web server have a connection to the Internet via a firewall.
  • the security mechanisms required on the Internet are generally not feasible because of the narrow free spaces.
  • connection of the web server to a communication network can advantageously be used to support the automation functionality if the web server is connected via a communication network to a web browser as an operating and monitoring system for the automation system controlled by the first software module.
  • This operator control and monitoring system can also be used for project planning, programming, software updates, generally for data communication and data representation.
  • FIG. 1 shows a system with web servers connected via the Internet, which perform different tasks
  • FIG. 2 shows a web server with automation functionality
  • FIG. 3 shows a schematic view of the structure of a web server with automation functionality.
  • a first web server 3 communicates directly with the Internet 1 via a connection 2.

  • a web browser 26 is connected to the Internet 1 via a connection 25.
  • a web server is a process on one computer - or distributed over several computers - and usually supplies a large number of clients (web browser on different devices) with information. This information can either be static on the web server or it can be generated dynamically by other utilities.
  • Usual communication partners connected via the Internet 1 are thus web servers in the configuration of the fifth web server 24 and web browser 26.

  • the web servers 10, 15 are linked to the Internet 1 via a firewall 8.
  • the firewall 8 effectively prevents inadmissible access via a communication link 7 to one of the web servers and thus to the drive 18 or the machine tool 13.
  • the web server with automation functionality is a so-called embedded web server 20, which contains as expansion module 21 a temperature controller for controlling a valve 22.
