Abstract

In an automation system, a large number of field devices (1, 2, 3, 4) are locally distributed in an installation which is to be automated and are connected to a control and/or engineering system (10, 11) via a communication system (5). The field devices (1, 2, 3, 4) have adjustable device parameters for which, in the case of at least some of these field devices (1, 2, 3, 4), access protection can be activated and deactivated via the communication interfaces of the relevant field devices (1, 2, 3, 4). In order to allow effective access protection for the device parameters throughout the installation, the control and/or engineering system (10, 11) is designed to input an access-protection activation or deactivation command, with access protection being activated or deactivated on all relevant field devices (1, 2, 3, 4) in response to the access-protection activation or deactivation command.

Description

AUTOMATION SYSTEM WITH ACCESS PROTECTION FOR OPEN FIELD DEVICES STORED PARAMETERS

The invention relates to an automation system with a plurality of locally distributed in a complex field devices that are connected via a communication system with an input means having control and / or engineering system, wherein at least a part of the field devices adjustable equipment owns and parameter at at least a part of this field devices is an access protection for at least part of the device parameters via the communication interfaces of the respective field device to the communication system activated and deactivated.

In automation systems for technical or industrial installations such. B. the process industry, production and manufacturing industry, building or network technology, result in the installation concerned locally distributed, decentralized field devices (process equipment) predetermined functions as part of the plant automation and replace this process, plant and / or device-related information, if necessary, with each other but always ingsystem with higher-level components of the automation system, including its guiding or Engineer- from. To the field devices include, but are transducers for pressure, temperature, flow, level, etc., analysis equipment for gas or liquid analysis, weighing systems, actuators, positioners for valves, regulators and other decentralized drives for electric motor drives. To exchange data within the automation system, the field devices in the decentralized peripheral region, optionally joined together along with decentralized control and regulation and control and monitoring, via field buses or other communication channels, wherein different field buses over bus coupler are connected together. The buses can turn with controls such. B. Programmable automation devices to be connected to a central plant, in which also the guiding or ene is gineeringsystem, so the central control, regulation, operation and monitoring, connected.

Field devices have adjustable device parameters such as a rule. B. limits for alarms or alerts, calibration curves, parameters in analysis algorithms for signal processing, etc. are usually set these parameters in the commissioning phase and stored in the field devices. these are between 10 and up to 1000 or more parameters for each device. these settings are not normally changed, but only for maintenance such during normal plant operation. As with a device replacement, or changes in process conditions.

The device parameters can be depending on the type or manufacturer of different ways to adjust, as through wireless or wired local operation with a programming device, via input means such as a key panel, directly on the field device and / or by means of special software programs that host on a computers are installed and communicating via the communication interface of the field device with this. The device parameters are at their entry or modification on display means such. B., visualized on the programming device or field device, via the display means as a rule, more equipment and plant information, such. B. Process readings are displayed.

Some field devices have an access protection, the password entry - why here for. As well as a PIN number is expected - required if settings are to be made or changed on the device. This access protection is deactivated for most devices, so that then the modification of device parameters is always possible.

If access protection is active, the devices can behave very differently depending on device type or manufacturer. Thus, can. As a password be entered directly via the input means at the device, after which additional dialogs are enabled with critical settings via the display means. In other field devices special telegrams are used for communication via the communication interface containing a user-specific password that must be transmitted with each write request. It's also devices whose password protection can only be removed via device-specific software, which is not part of the control or engineering system. added to this heterogeneous behavior of the field devices is that the structure of the password of device is different from the device. Here, the password for. For example, be a two-digit numeric code that permanently implemented in the firmware of the device and can not be changed, but also consist of a sequence of arbitrary ASCII characters.

In a conventional system with hundreds of field devices from different device types this different device behavior causes them all individually and have to be locked with different methods. In an automation system in which the field devices work within a network, so the device function access protection is according to experience perceived as annoying and frequently disabled because otherwise be locked complicated and extended by the different device behavior, the commissioning or servicing work. On the other hand, a great harm can result in a system just by adjusting device parameters by unauthorized persons. In particular, can the local operation on the unit activate access protection at any time parameterization and operation outside the control and / or engineering system to.

The invention is therefore based on the object to enable with simple means an effective and easy to activate or de-activated access protection for device parameters of field devices in an automation system. According to the invention the object is achieved in that formed in the automation system of the aforementioned kind, the input means of the control and / or engineering system for inputting an access protection activation or -Deaktivierungs- command and that the control and / or engineering system is adapted to activate in response to an access protection activation or -Deaktivierungsbefehl access protection on all its field devices on or off.

From the control and / or engineering system, all those field devices so leave with a single command at least protect against access to their security-related device parameters, each with a tion interface on their communication activatable or deactivatable access protection. This protection can be reversed at a later date for all affected field devices from the control and / or engineering system using a single command. Of course, the access protection for the device parameters by means of the respective proposed device-specific method, for example by entering a password can continue for each individual field device individually switched directly through the input means on the device on or off. The access protection to the equipment is provided with a necessary for the deactivation password to prevent unauthorized access may compromise the protection of any point in the communication system via the communication interfaces of the devices. The password can make from which the control and / or engineering system and thus legitimate

Staff entered or automatically generated by the control and / or engineering system. For the (central) locking or unlocking total and the (local) single locking or unlocking of the device same, preferably but different passwords may be provided so that all devices encrypt and centrally through a single password to unlock, the z , B. is assigned by the control and / or engineering system and only this loading, is known as the single locking and unlocking the unit is done by individual passwords.

For such field devices, wherein the access protection by receiving an access protection activation commands can be activated together with a serving for later deactivation password, the guidance and / or engineering system sends in response to an access protection activation command, the access protection activation command and password in question to all field devices. The password is then stored in the field devices, to enable authorized access to the device parameters and later the deactivation of access protection.

For example, the parameter assignment via the acyclic channel from the master class 2 are transmitted to the field devices at the Profibus DPVl fieldbus. The parameterizing data are normally distributed over different data sets. Now if access protection is activated, it must in addition to the parameter assignment according to the invention, a

Password record be sent to the field device containing encrypted password. The device compares the incoming password with the stored password. If the passwords match, the parameterizing data are transferred, they are different, the records to the output of a corresponding error codes are rejected. is to activate protection in the field devices with the password record the access protection activation command, for example in the form of a single activation rungsbits sent to the devices. then the devices enable their access protection and save the password permanently in device internal Storage from. If access protection can be disabled, with the password record the access protection deactivation command such. As a single Deaktivierungsbit, and the password sent to all devices. Compare instrument the incoming password with the stored passwords and disable if they match the access protection. In this manner, field devices, different manufacturers, be protected with the same password.

To increase security, the password contained in a data management of the control and / or engineering system device identifiers can, for example, the tag name of the device, device individually linked, in particular encrypted, and the field devices will be sent. In this way, the user assigns Although only one password for all field devices, but which is encrypted differently for each device and stored.

For field devices that have different mechanisms of activation and deactivation of access protection to which can be accessed via its communication interface, however, a common activation or deactivation of access protection is achieved in that available for at least a portion of the respective field devices each having a device-specific software is, which provides a visible outward interface is an activation or deactivat vierungsmethode for access protection are available, and that the control and / or engineering system is adapted in response to the access protection rungs--activation or -Deaktivierungsbefehl zoom pull the rack available th activation or deactivation methods and perform. Act which is stored in the data management of the control and / or engineering system - at the device-specific software, it may, for example, drivers such as Device Type Manager (DTM) Field Device Tool (FTD) or an electronic device description (EDD Electronic Device Description) , The control and / or engineering system searches in response to the Access Protection activation or -Deaktivierungsbefehl for existing activation or deactivation methods and executes them. Since z. B. only device EDD must be expanded to include this particular function, existing field devices can be expanded easily and without firmware changes to this system function. For such field devices which do not allow activation or deactivation of access protection through its communication interfaces, can be enabled in response to an access protection-activation or -Deaktivierungsbefehl a feed handle lock in a data storage of the control and / or engineering system be on or off, wherein the control and / or engineering system blocks access to the device parameters when the access lock is activated in the data management. Then the in question field devices behave in terms of their communication interfaces such as devices with access protection. However, the device in question can be reconfigured unprotected on any existing local operation.

The control and / or engineering system preferably has a, in particular according to the standard guidelines of Microsoft Windows designed, on graphical user interface, in which the access protection activation or -Deaktivierungsbefehl is selectable, for example, by clicking on a control panel. Network access protection activation or -Deaktivierungsbefehl can be integrated into a serving for parameterization of field devices view of the user interface.

As can be contained, etc. in a plant confidential information such as batch information, recipes, technological parameters, access protection according to the invention for field devices with display means advantageously on the display given, particularly confidential, plant and / or extends device specific information is.

To further illustrate the invention, reference is made below to the figures of the drawing; In detail:

1 shows a block diagram of an automation system and Figure 2 is approximately command an example of a user interface for entering the access protection activation or -Deaktivie-.

1 shows in simplified schematic representation of an example of a process automation system with field devices 1, 2, 3, 4, to be controlled in one and / or perceive predetermined process to be controlled measurement, control and regulation functions, while process via a communication system 5 , functional and / or replace the device-relevant data with the process automation system. For this purpose, the field devices 1, 2, 3, 4 via a field bus 6, z. B. according to the PROFIBUS standard, of automation devices 7 and 8, z. As programmable logic controllers (PLC), which in turn are connected to a central system bus 9 with a superordinate control and engineering system 10,. 11 The control and engineering system 10, 11 has a data storage 12 in which inter alia the behavior and properties of the field devices 1, 2, 3, 4, z. Example in the form of electronic device descriptions (Electronic Device Description) is stored. Such automation system can in principle have a different number of automation levels, in which the individual components of the automation system are located and communicate with each other over an existing communication channels from different communication system.

As shown on the example of the field device 1, the field devices 1, 2, 3, 4 have input means 13 for inputting and amendments tion of device parameters and for querying device and

Process information such as the device parameters and process values ​​recorded on. The information are visualized on display means 14th but the input and display can also have mobile panels 15 or other programming means such. As a Process Device Manager (PDM) 16, carried. confidential information contained in the process equipment 1, 2, 3, 4, safety-relevant device parameters are provided with a confidential ID and can be displayed or changed in response to the input of a password. The input of the password can the device's own input means 13, take place the portable device 15 or in the context of data transmission over the communication interface of the device 1, 2, 3, 4 to the communication system. 5

The input of a single access protection activation command to the control or engineering system 10, 11 allows simultaneous activation of the access protection on all field devices 1, 2, 3, 4. It will be depending support the individual devices which methods of access protection, a Zugriffsschutz- activation command sent together with a password to the device, drawn the electronic device descriptions in the data management system 12 zoom in on the identification and design of the device-specific access control methods or an access barrier in the data storage 12 are activated, which for the control or engineering system 10, 11 and all components of the automation system, that communicate over the master or engineering system 10, 11 with the field devices 1, 2, 3, 4, blocks access to the device parameters.

The total locking of the field devices 1, 2, 3, 4, 11 can be lifted by a single access protection deactivation command to the control or engineering system 10. The Gesamtentriegelung is protected by a password that is generated automatically in the total locking of the operator of the control or engineering system 10, 11 or from this.

Figure 2 shows an example of a graphical user interface of Windows control or engineering system 10, 11 to enter the access protection activation or -Deaktivie- approximately command by clicking the panels "Device comparable bars ..." or "unlock device .. . "and then enter a password.

The user achieved by the inventive Total charges access protection in the form of a "lock-broadcasts" a significant improvement of access protection of its investment. Contrary to past practice, the access protection is no longer shut down due to lack of manageability, but with a "click" for complete automation enabled anläge. Parameters can then change only by authorized personnel.
