Definitions
- the present invention relates to a programmable controller according to the preamble of claim 1.
- Programmable controls also known under the terms programmable logic controller (PLC) or programmable logic controller (PLC) are also used in automation technology, among other things. They contain the appropriately programmed control codes for executing the desired automation functions.
- PLC programmable logic controller
- PLC programmable logic controller
- automation systems can be created by configuring and configuring individual automation devices in accordance with the desired automation system.
- very abstract programming languages are generally used, which in the past have increasingly been adapted to the very special needs in automation technology. These programming languages are familiar to the project planner of such automation systems. Such programming languages and program codes are rather incomprehensible to a user of such automation systems. A user-specific adaptation of the automation system without detailed specialist knowledge is therefore not easily possible.
- object-oriented programming languages such as JAVA.
- object-oriented languages are relatively simple and therefore easy to understand.
- they have the disadvantage that, in contrast to the programming language commonly used in automation technology, do not run deterministically, which can ultimately deteriorate the performance of the controller.
- the object of the present invention is therefore to provide a programmable controller which enables both good controller performance and simple adaptation of the automation system to the needs of the user.
- the programmable controller having the features of claim 1, the programmable controller having a first area for storing and executing control codes for automation devices, programmed in a first programming language, and a second area which is connected to the first area via at least one Interface is connected, and wherein the second area is programmable in a programming language that differs from the first programming language.
- the first programming language is a programming language that is common in automation technology, such as that of STEP 7, and the second programming language is an object-oriented programming language, in particular Java.
- the well-known configuration software Step 7 offers the advantage that good control of the automation devices continues to be achieved.
- the advantage of JAVA is that, as an object-oriented language, it is also relatively easy for the user to understand and can therefore be used.
- the control codes can therefore continue to be on the programmable controller in a programming mode which is customary and suitable for automation technology. create speeches.
- additional user-specific routines such as, for example, diagnostic functions or additional automation functions, can be created in the simplest manner by a user on the same programmable controller, and the automation system can thus be supplemented in a user-specific manner.
- the first area containing control codes that are certified for a certain number of automation devices and secured against changes
- the second area is freely accessible programmable, in the simplest way in the second Additional user-specific automation functions or diagnostic functions can be programmed without having to change the actual core routines stored in the first secure area. This ensures that the once created and certified control codes for the core routines for operating the automation system cannot simply be changed, and thus the certification for the programmable controller would possibly expire.
- FIG. 1 schematically shows a programmable controller S with a first area A and a second area B. Both areas A and B are shown in dashed lines to indicate that the two areas within the programmable controller do not necessarily have to be spatially separated. As indicated, both areas A and B are connected to one another via at least one internal interface P, preferably via a high-performance, highly proprietary interface.
- the programmable controller S is connected to the corresponding automation devices 1, 0 via a further interface D, such as a Profibus-DP known in automation technology. These can, for example, individual actuators or sensors, entire devices or assemblies, etc.
- an interface N can be provided in order to connect further devices, such as devices for operating and monitoring, to the programmable controller, for example via an Ethernet or an Internet.
- a single programmable controller is now divided into two sub-areas A and B, both sub-areas being programmable in different programming languages, in particular a first area in a automation technology customary and a second area in a simpler object-oriented programming language.
- cher sauce - so all essential control codes for the operation of the automation system and communication with the associated devices I and 0 are for example in the area of safety-A.
- This first area A can be secured against unauthorized changes. This enables safe control of automation devices by the programmable controller, which ultimately also enables a corresponding certification of this programmable controller.
- the second area B is freely programmable, in particular in an object-oriented programming language such as JAVA, in order to give a user the opportunity to add additional user-specific routines as simply as possible. Since, as a rule, such user-specific routines will also fall back on data from the actual control from area A, a high-performance proprietary interface P is provided between areas A and B. This interface P can be used, for example, to access the process variables and data known in area A from the diagnostic routines created in area B for this data evaluate. Furthermore, routines could be created in area B, which forward this data from area A to other devices C, such as web servers, etc., via interface N. In addition, routines could be created in area B that implement very special user-related automation functions, but for which the programmable control does not have to be certified.
- an object-oriented programming language such as JAVA
