Definitions

  • the invention relates to a method for licensing and / or access authorization of software modules for indus ⁇ -industrial controllers Us / or computer systems.
  • the object of the invention is to provide a user of software modules with a simple, flexible method for licensing and / or access authorization of software modules which is adapted to his changing requirements and which can be used in particular in distributed systems.
  • this object is achieved in that a customer acquires value points as a user authorization for the desired software modules, each software module being assigned a value in the form of value points and that the customer is authorized if the number of value points acquired by the customer is at least the sum of the value points of the currently desired software modules is reached, whereby the current balance between acquired and used value points is continuously calculated and monitored by a license manager.
  • software module is to be used synonymously with software program or software component.
  • a major advantage of the invention is that a customer does not conclude a license agreement for the software modules used and their number, but acquires a license agreement for value points.
  • the customer can use the software modules required in a flexible and needs-oriented manner within the "Value Points License" he has acquired. Instead of a price, the software modules are assigned a value in the form of value points, each value point having a price. Changes to the customer's requirements or new software components do not require a change in the license agreement if the value of the software modules currently required is compensated for by the value points already acquired.
  • the use of value points as license The use of software modules greatly simplifies the administration and license administration of software for a system, but also for an entire company.
  • the licensing procedure is simplified by the invention.
  • the licensing also enables a high granularity and easy combinatorics of the software modules.
  • the invention permits function-neutral pre-orders, ie a buyer does not have to commit himself to certain software modules when acquiring a license, but can acquire a number of value points and use them for any software modules.
  • value points as the authorization currency for the use of software modules, the customer can be satisfied with changes in his software requirements without having to change the license agreement. This saves additional administration and administration processes.
  • the customer can thus buy a voucher for a number of value points, so to speak, whereby he is allowed to flexibly exchange and exchange these value points in software modules.
  • the customer can thus individually assemble his module delivery and does not have to accept packages prepared by the supplier.
  • a further advantage of the invention is that the customer is authorized to use the software modules that are currently desired when the number of value points already acquired by the customer reaches at least the sum of the value points of the software modules currently desired.
  • the usage authorization for customers is done by simply checking the total balance of the value points. Because dedicated value points are assigned to each software module, it is very easy to compare the sum of the value points of the currently desired software modules with those from the license agreement acquired value points are carried out. Insofar as the customer's value point account is not exceeded by the sum of the value points of the currently desired software modules, the customer is granted user authorization.
  • a license manager permanently records the current number of required value points and compares them with the existing ones, a customer can be billed according to need or use. With the license manager, newly acquired value points can be easily integrated and taken into account in terms of licensing, but also additional value points required in an application can be easily recognized.
  • the license manager continuously determines the "value point target", i.e. the sum of the value points of all currently required software modules, and compares them with the "value point having", i.e. the total credit of value points acquired through the license.
  • a first advantageous embodiment of the invention is that the license manager is implemented as a mobile agent. This makes the licensing process very easy to use in distributed environments.
  • the software modules that are subject to licensing can run on devices that e.g. Are connected via fieldbus connections, but also Local Area Network (LAN) or Internet or. Intranet connections are possible.
  • LAN Local Area Network
  • Intranet connections are possible.
  • Another advantageous embodiment of the invention is that the system automatically calculates the value points required for an application. A user thus immediately recognizes which license costs (in the form of value points) the configuration of software modules selected by him, ie his applications, causes.
  • the required value points can be determined by the license manager or, for example, by a routine in the engineering system for industrial controls.
  • Another advantageous embodiment of the invention is that the value points are transmitted to the industrial controls or to the computer systems via a data line or via the Internet. This means that no data medium or other hardware component is required to transfer the license currency (value points) to the customer.
  • Another advantageous embodiment of the invention is that the value points are supplied on a data carrier that is already available for the operation of the control or the computer system anyway. This makes handling on the control or computer system easier, but also saves storage space and storage costs.
  • Another advantageous embodiment of the invention is that the value points are fed to the control or the computer system on a memory card.
  • a memory card is usually used in control devices anyway and can be easily inserted into the slot provided.
  • MMC memory cards are very suitable as carriers of information due to their size and shape. MMC memory cards are comparable in appearance to a small SIM card as they are known on mobile phones.
  • a further advantageous embodiment of the invention is that the value points are fed in at one point or in one device or at different points, ie on several devices for the entire system or for the entire system.
  • This enables a customer, for example, to obtain licensing information (license currency in the form of value points) for software components that cover the entire system or affect the entire system at a single point (e.g. device) and in the same way.
  • This greatly simplifies license handling for a customer, particularly with regard to distributed applications and network operation.
  • a further advantageous embodiment of the invention is that the target / actual comparison of the value points required for the access authorization takes place during the installation of the software modules. This means that it is only when a customer installs the software modules they have purchased on a device or system that a check is made as to whether the number of value points they have acquired is sufficient for the desired software modules.
  • the fact that the customer's value point account is only debited when the software modules are loaded onto a device or system means that the check as to whether the customer is authorized to use the software modules takes place at the point in time at which the customer actually intends to use the To use modules.
  • the billing of the value points is done for the customer according to need.
  • Another advantageous embodiment of the invention is that the target / actual comparison required for the access authorization takes place when the software modules are used.
  • the value points can thus be linked to the number of incarnations or instantiations of the software modules. This makes it possible to provide a customer with user-oriented licensing procedures for their respective requirements.
  • a customer who uses a software module for motion controls e.g. a technology package
  • the "Positioning” technology package includes the "Positioning axis" technology object.
  • the number of incarnations or instances of the technology The "positioning axis" object or other technology objects are billed, ie his value point account is debited with the number of incarnations or instances of the technology objects. Due to the incarnation-related authorization at runtime, a customer's value point account is only debited by those software modules that he really needs and uses for his applications. There is therefore a very finely granular billing mechanism, and a customer only has to pay for the functionality required and used.
