  • the on the communication device attached cable can be removed with its End are plugged into one of these connections.
  • the connection consists essentially of a mostly Fieldbus interface in combination with a power supply for the passive, so no own power supply containing Communication device.
  • About the fieldbus are at the communication device all plant-wide data available.
  • a detection of the attachment of the communication device takes place so far, by using a separate line a yes / no signal for the assignment of the connection from this to the plant control is transmitted.
  • the communication device After plugging in the communication device at a desired connection point and run up its operating program is at the communication device usually presents a start screen, from which the Operator by selecting appropriate submenus up to the corresponding process data of the plant, which is currently advancing are interesting for him. This is for example information about the plant part, in front of which the operator is currently located. Especially for very large plants that have a variety to provide information on the communication device, it is For the operator often very tedious, to the desired information penetrate. After each change of the communication device to another port, this process must be repeated be because the communication device after connecting behaves the same way on each connection.
  • Object of the present invention is to provide a method and to provide a facility to facilitate the operation of the Communication device to allow.
  • connection of the communication device can be made via a connection cable or also stationary, e.g. by inserting into one attached to the system docking station done.
  • the Communication device can be detached from the connection at any time, by e.g. reconnected to another location on the machine to become.
  • the identifier identifies the connection e.g. with a for this assigned name in the form of an alphanumeric string like "machine center” or with an example also printed on the port running number like "03". In any case, the identifier describes a specific one Connection unambiguous.
  • the identifier transmitted to the communication device is in an initialization, the on the Connecting the communication device to the port follows, the identifier is then available in the communication device and can be used there.
  • the initialization mode is upstream of the normal mode.
  • the identifier is available if the Communication device in the normal mode for process coupling with the system changes. This information can be in the communication device can be used, e.g. to get information about to display the connection. Also, depending on the identifier in the communication device e.g. certain security features be unlocked in the communication device not are available when connected to other terminals is.
  • the connection that unlocks the safety functions here is e.g. only accessible to the factory manager.
  • a clear information available to which of the various ports the communication device is currently connected is displayed.
  • the plant operator can, for example on the display of the communication device this information are displayed.
  • the user can then click on e.g. directly a submenu corresponding to the connection in the software of the communication device and thereby passes fast and secure to information, which for him am relevant connection point are relevant.
  • a normal mode is selected after the initialization operation, the communication device changes in the selected normal mode.
  • the normal modes can differ, for example, in that different Information is available in the normal modes be put. This information may e.g. so be chosen that they only information about the condition the plant in the immediate area of a certain connection location of the communication device. Because the Normal mode depending on the identifier and thus dependent from the point of connection where the device is currently located is an automatic selection of process data possible at a certain connection location of the communication device are displayed. A connection point dependent User guidance is possible.
  • the data between system and Communication device exchanged via a data protocol.
  • the transmission of the identifier takes place with the same data protocol.
  • already existing Communication devices may possibly by pure modification of the operating program and without intervention in their hardware for the process according to the invention can be improved.
  • This brings a significant cost advantage for the plant operator because he does not have to buy any new communication devices.
  • the cable leading to the communication device is not through extra lines too thick and unwieldy and the Number of assignable identifiers is not limited.
  • the object underlying the invention will continue solved by a device for communication with a system, in particular for operating or observing an automation system in industrial manufacturing, the Plant a connection for a communication device for data exchange having the plant.
  • the communication device is in an initialization mode or in a normal mode operated.
  • the port is a storage device in which an identifier is stored, which is the connection clearly identifies.
  • the identifier is during the Initialization operation to the communication device transferable.
  • the storage device can be a separately in the system existing memory module, which e.g. about the plant internal Fieldbus in particular with the plant control and connected to the port. It can also be a Program module of the control program of the system act, in which stores the identifier as a fixed value or string is.
  • the memory device is after the connection of the Communication device connected to this, so that the identifier during the initialization operation to the communication device is transferable. With the device can be perform the method mentioned in claim 1, what to leads to the advantages mentioned there.
  • the storage device is integrated afterwards.
  • the connection as a whole unit includes a memory device in the form of a DIP switch. Is the storage device in the Integrated connection, so this is also physically directly on Connection arranged.
  • the association between in the storage device stored identifier and connection is thus For example, during maintenance work at any time directly on the connection verifiable or adjustable. When replacing a e.g. mechanically defective connection with integrated storage device can this directly with the exchange again with the identifier identifying the port is assigned.
  • a further preferred embodiment provides that the Plant has multiple connections and each connection one associated with another identifier during the initialization operation from this to the communication device transferable is. Is each port assigned a different identifier? so each connection is clearly marked.
  • each identifier is assigned a normal operating mode, it can after passing through the initialization mode that of the transmitted Identification associated with selected normal mode and the communication device in the selected normal mode switch.
  • a preferred embodiment of the invention provides that the communication device at the connection via a data line can be connected, and via the data line, both the communication data transferable from and to the system and the identifier are.
  • This allows for communication devices that for process coupling, ie for the exchange of communication data from and to the plant anyway have a data line, that over the same data line and the identifier transferable is.
  • Existing communication devices thus need not additional lines for the identification transmission can be extended and can with the inventive Procedure only by modifying your operating program continue to be operated.
  • Fig. 1 shows an automation system 2 for industrial Production with a communication device connected to it 4.
  • the automation system 2 comprises a machine 6, a machine 8 monitoring controller 8 and three connections 10a-c, to which the communication device 4 can be connected is. All mentioned components of the automation system 2 are connected via a field bus 12 to each other mutual data exchange.
  • a memory device 14 is included in each of the connections 10a-c.
  • a numerical value which is uniquely associated with the corresponding port 10a-c is. This numerical value serves as identifier for the corresponding Connection 10a-c.
  • the terminal 10a thus carries the identifier "01", the connection 10b "02" etc.
  • Each terminal 10a-c has a connection socket 16.
  • the Jacks 16 and memory devices 14 are also connected to the field bus 12.
  • In the connection sockets 16 is also a power supply, not shown integrated.
  • the communication device 4 which is shown in plan view is, has at its top buttons 18, which the operation of the communication device 4 and the controller 6 of the Automation system 2 serve. Furthermore, the communication device 4, a display 20 is present on the process data the automation system 2 and operating instructions of the communication device 4 are shown. On the communication device 4 is a connecting line 22 with a connector 24th attached, which is inserted into the sockets 16.
  • connection line 22 at the terminal 10b is through the shown dashed line, so it is in both Cases around the same connection line 22.
  • the automation system 2 During normal production operation of the automation system 2 is not a communication device at any of the ports 10a-c 4 connected. The connection is made first, if the automation system 2 e.g. serviced for maintenance or should be observed.
  • the operating software in the communication device 4 is ready, then is via the connecting line 22 is a connection from the communication device 4 to field bus 12 manufactured. Because the communication device 4 is still in initialization mode, is now stored in the memory device 14 Identification via the fieldbus 12 and the connecting cable 22 transmitted to the communication device 4. In Fig. 1 this is the identifier "01". The communication during the entire initialization operation takes place along the communication route 26, which is shown in Fig. 1 by a double arrow that is between the memory device 14 and the communication device 4 runs.
  • the transmitted identifier "01" is now from the program in the communication device 4 evaluated, whereupon the communication device 4 detects that it is connected to connector 10a.
  • This information can now be displayed either on the display 20 or one of several possible normal modes of operation, namely the corresponding the identifier "01" to be selected.
  • connection 10a is off e.g. only the machine part 30 of the machine 6 visible.
  • To the Machine part 32 of the machine must be able to see itself the plant operator, for example, go to port 10b, from where this machine part 32 is visible.
  • the communication device 4 the operator removes the connector 24 from the socket 16 of the terminal 10a, moves to port 10b where it carries the connector 24 in the socket 16 of the terminal 10b a. In Fig. 1, this case is shown in dashed lines.
