Definitions

  • the invention relates to a system and a method for generating and / or processing a message from a control device and / or an automation device via the intranet and / or the Internet.
  • the automation devices In production or manufacturing systems, the automation devices, ie the control devices and the automation devices, generate messages during operation, which are either sent to human users or to other devices in the system.
  • the messages generated by the automation devices can be both alarms that are triggered in the event of system malfunctions and messages that arise during normal system operation.
  • the latter can be, for example, the cyclical reporting of process data for trend analyzes.
  • it is necessary to supplement the respective message with additional information before forwarding it to the addressee. This can be, for example, texts that are added to a message number.
  • the messages are usually not sent unidirectionally from the sender to an addressee; rather, the message recipient sends a reply back to the message sender in the form of a receipt.
  • DE 198 37 650 AI discloses a system, a method and a control device for generating a message as an e-mail via the Internet or intranet. The e-mail is given an address and sent directly to the recipient.
  • the invention is based on the object of specifying a system and a method which easily generates and processes a message from a control device or an automation device.
  • the invention is based on the finding that it is increasingly important to process messages which are generated by automation devices in systems with the aid of a system which is as universal as possible and which functions as a message server. Such a universal system for recording and forwarding messages requires connected
  • Units for further processing of the messages do not require any special adaptation of the interfaces, as is still required today in the operating and monitoring systems used.
  • the system according to the invention also offers the possibility that all control devices present in the system send their messages to a message server. This will process the messages and also the Configuration of the automation devices is enormously simplified, since an automation device only sends its messages to exactly one message server and also receives the answers from it. Time-consuming addressing of the messages is not necessary.
  • the use of a message server for processing automation messages thus leads to an improvement both in system operation and in the configuration of the system.
  • An advantageous embodiment of the invention is characterized in that an intranet and / or an Internet is provided as the data transmission system. If an intranet or an Internet is used in addition to a universal message server for receiving and forwarding messages for data transmission, remote access to the messages via the network, in particular the Internet, is also possible for an operator of a system. A remote request for process values or information in the event of a system malfunction, in which an alarm is reported, would be possible for a production manager or maintenance engineer who is not at the site. Using the intranet or internet saves costs and increases flexibility.
  • a further advantageous embodiment of the invention is characterized in that the message server is designed as an Internet message server. This enables the server to be installed anywhere in the network and, in addition, an Internet message server does not require a special protocol, but can use the standard Internet protocol when processing the messages.
  • the Internet message server is designed as an e-mail server for an asynchronous exchange of messages.
  • the messages sent by the automation devices are automatically buffered on the server in an inbox until they reach the actual addressees can be sent or picked up by him.
  • the addressees do not have to be permanently connected to the message server via a data connection through the buffer system. Rather, the messages can be picked up from the server at any time. This is particularly advantageous if an addressee is in an inoperable state. In this case, the message is not lost, but is made available in the server's mail basket until the data connection is restored or the message recipient is available again in the system. This prevents loss of messages.
  • a further advantageous embodiment of the invention is characterized in that the Internet message server is designed as an instant messaging system for a synchronous exchange of messages.
  • the messages between the automation devices and the receivers can also be exchanged approximately synchronously. In the case of time-critical messages, this is advantageous since there is no delay in forwarding the message by temporarily storing it in a mailbox on the server.
  • a further advantageous embodiment of the invention is characterized in that means are provided for assigning the messages to at least one addressee.
  • the messages from the automation devices received on the message server are assigned to the respective intended addressees via a distribution list, depending on the keys that are attached to the messages.
  • the main advantage of centrally storing the distribution lists on the server is that the distribution lists can be easily maintained centrally.
  • the automation devices do not have to be informed of any additional information about newly added message recipients or new addresses of recipients via a configuration interface.
  • the automation devices always send their messages to only one Address, namely the server on which the messages are then placed in the corresponding outboxes for the addressees. Instead of updating the addresses on each automation device involved, only the distribution list stored on the server needs to be updated when the addressees change. This eliminates the need for time-consuming project planning.
  • a further advantageous embodiment of the invention is characterized in that the control device and / or the automation device has means for receiving a confirmation message sent back from the receiving device to the control device and / or the automation device and means for automatically marking a message as acknowledged.
  • the sender can be informed that the message sent has actually reached the recipient sought.
  • the sender can confirm the acknowledgment with a receipt.
  • the possibility of establishing such a feedback process in the system simplifies the processing of the message transmission, since the individual devices involved are informed about the respective traffic jams. Documentation of the information transfer between the devices involved is also possible. Such a feedback process thus facilitates the correct handling of communication between the devices.
  • a further advantageous embodiment of the invention is characterized in that the means for processing a message can be coupled to the message server by adding further information.
  • the majority of the messages received generally require further processing, ie texts or additional information are added to the messages.
  • Complex further processing of the messages can also be carried out, which can consist, for example, of the processing unit determining the cause of the fault for a fault message using a fault tree and forwards them in text form to a maintenance engineer.
  • a further advantageous embodiment of the invention is characterized in that the means for processing a message are identified via mailboxes and / or message channels.
  • the advantage of the embodiment according to the invention is that no special adaptations of the interfaces or the data transmission systems have to be made between the message server and the units for further processing. Any processing units that are on the market and that use the standard e-mail or standard instant messaging interfaces can be coupled to the Internet message server. Time-consuming programming of specific interfaces is no longer necessary.
  • a further advantageous embodiment of the invention is characterized in that the means for processing a message have further means for forwarding the message to a person and / or further devices present in the system.
  • the means for processing a message have further means for forwarding the message to a person and / or further devices present in the system.
  • a maintenance engineer or an operator of the system can be informed about specific alarm or error messages enriched with additional information.
  • the exact cause of the error can be communicated to the maintenance engineer via the additional information and the processing unit can also immediately forward it to him.
  • this embodiment according to the invention also offers the possibility, for example, of sending process data to a system for historical data management, which collects, archives and, if appropriate, also statistically evaluates the process values of all automation devices involved in the system.
  • a further advantageous embodiment of the invention is characterized in that further means are provided for sending a message response and / or acknowledgment of a message by a person and / or a device to the control device and / or the automation device.
  • the advantage of this is that the final recipient is able to confirm receipt of the message by himself, either as a person or as a device in the system. It only has to be confirmed if a confirmation of receipt is also necessary. There is no need for unnecessary confirmations, which leads to a reduction in data flow in the system's network.
  • the response of the person or the device like the message, can be processed by the connected processing units.
  • the automation device thus receives specific feedback on its original message.
  • FIG. 1 shows a schematic representation of an exemplary embodiment of the system for generating or processing a message from an automation device via an intranet or the Internet using an Internet
  • the data transmission system 4 is designed as an intranet or Internet 5.
  • the Internet message server 2 has an inbox 14 in which the messages are received.
  • the intranet message server 2 also has so-called distribution lists 12, With the help of which the messages received are assigned to addressees 13.
  • Processing units 7 are coupled to the intranet message server 2 and can receive messages 3 for further processing.

  • means 15 for sending a message response or acknowledgment 6 to the automation device 1 both a person 10 and a device 11 can acknowledge the message.
  • the special feature of the system 17 shown in FIG. 1 essentially consists in the fact that all automation devices or controls 1 present in the system 17 send their messages centrally to an Internet message server 2.
  • the use of a universal Internet message server 2 also enables a procedure in which all the automation devices 1 involved can always send their messages to the same addressee, namely the intranet message server 2, without further specification of addresses. A complex configuration when changing the address or changing distribution lists 12 on the individual automation devices 1 is omitted. Overall, the system 17 according to the invention described in FIG.
  • the use of the Internet or intranet 5 also enables authorized parties to access the messages from outside the system 17. This is particularly advantageous when processing alarm messages, since a maintenance engineer who may not be directly on the system can use normal e -mails is informed about the status and is informed of the alarms. Under certain circumstances, the maintenance technician can carry out a diagnosis directly from a distance using the information made available to him in the notification and, if necessary, issue corresponding instructions to the personnel present on the system.
  • expert knowledge need not be available at any time directly on site. It is also possible to query process values remotely via the Internet and e-mail, which ensures an overview and control of the production processes from outside the system.
  • the use of the Internet message server 2 as an e-mail server enables the incoming messages 3 to be buffered in a mail basket 14 until the addressees pick up their messages 3. This is particularly advantageous in the case of messages 3 which are intended for people who can easily access these messages 3 at any time via an e-mail client. However, it is also advantageous that messages can be buffered for further devices 11 or for processing units 7 until the receivers are ready to receive the messages, since this means that in the event of a potential failure of one of the units 7 and 11 involved, the messages are lost No reports. The notifications are also delayed when the systems are running again.
