Definitions
- the invention relates to a protective or process control device for a power supply system, in which a plurality of device-internal device modules for the purpose of a data exchange with each other.
- Devices in the field of digital Druckleitleit- and protection technology are preferably equipped with a modular hardware platform, so that they can be easily and cost-optimally adapted to the respective requirements in terms of expansion and functional level.
- Such requirements include, for example, the type and performance of communication interfaces, the number of binary inputs and outputs as well as the functional density and performance of the device.
- the platform properties of the protection and control technology devices are currently provided on the hardware side by an internal device bus.
- the protection devices of the company SIEMENS AG are known, which are sold under the product name SIPROTEC and equipped with a parallel address, data and control bus.
- the invention has for its object to provide a protection or control technology device, which has a modular design and makes it possible, if necessary, easily and inexpensively exchange device modules or use additional device modules in the device; Nevertheless, it is supposed to be a very high degree
- Ethernet switch - hereinafter also called Ethernet switch - are in communication with a device-internal Ethernet ring and exchange their data over this.
- a significant advantage of the protection or control technology device according to the invention is the fact that this relies on the known Ethernet technology with respect to the device-internal module connection; this makes it possible to use generally accessible and mature driver components.
- Another essential advantage of the protection or control technology device is that it provides a very high level of data security because of the existing device-internal Ethernet ring, because redundancy exists because of the ring structure: namely, if the Ethernet ring at one point is intentional or unintentionally interrupted, the data connection between the device modules connected to the ring still remains intact because the ring allows data transfer around the point of interruption.
- the 3-port switches are formed by monolithically integrated components, in particular in FPGA or ASIC design.
- Ethernet ring has real-time capability. is staltet.
- the Ethernet ring can work, for example, according to the known Profinet standard "i-RTE".
- a cut-through method is understood to mean a method in which incoming data on an Ethernet switch is forwarded without intermediate storage, if these are not intended for the device module connected to the respective switch.
- the device modules are attached to a so-called DIN rail, as it is known for example from fuse boxes and the like;
- a DIN rail makes it possible to integrate device modules into the Ethernet ring in a very simple manner later by sliding the device modules located on the DIN rail at the desired coupling point or by applying the additional device module to the outer edge of the DIN rail and to the other device modules the Ethernet ring is connected.
- the Ethernet switches are formed by an FPGA or ASIC device; Such components enable low production costs.
- Ethernet switches are integrated in one and the same monolithically integrated component, for example an FPGA or ASIC component. and form a fully integrated Ethernet ring.
- a data transfer in a very simple manner is made possible by the fact that the device-internal modules are connected from the outside to the monolithically integrated module; the ring-related data transfer then takes place within the monolithically integrated module.
- an integrated electronic component in particular an FPGA or ASIC module is considered, in which - for example, for implementation in a protection or control equipment - a complete data transmission ring with a plurality of ring element switches is integrated such that from outside at least two of the ring element switches are electrically accessible and can be controlled and that data from one of the at least two ring element switches can be transmitted to another of the at least two ring element switches.
- a complete Ethernet ring with a plurality of Ethernet switches is integrated in the component; these are preferably all electrically accessible and controllable from the outside and allow data transmission among each other.
- a DIN rail is also seen, in which an ethernet-compatible ring line is integrated so that can be formed on the top hat rail Ethernet switch using the ethernet-compatible ring line an Ethernet ring.
- an Ethernet ring With regard to a simple mechanical construction of an Ethernet ring with such DIN rail, it is considered advantageous if the Ethernet switches to be connected to the Ethernet ring have side-mounted network connections which, when the Ethernet switches are pushed together on the hat rail with each other to establish a data connection.
- FIG. 1 shows an exemplary embodiment of a protection or process control device with an integrated switch Ethernet ring
- Figure 2 shows an embodiment of the mechanical structure of the device according to Figure 1 and
- Figure 3 shows an embodiment of a suitable device for the device according to Figure 1 block in which a complete Ethernet ring is monolithically integrated.
- FIG. 1 shows a protective or control device 10-referred to below as protection device 10-that includes a main CPU 20 and further device-internal device modules, specifically a binary input module 30, a communication module 40, a measured value module 50, and a command module 60 Is provided.
- protection device 10- that includes a main CPU 20 and further device-internal device modules, specifically a binary input module 30, a communication module 40, a measured value module 50, and a command module 60 Is provided.
- the main CPU 20 and the four device-internal device modules are connected to one another via a real-time capable switch Ethernet ring 70.
- the connection of the main CPU 20 and the four device-internal device modules 30, 40, 50 and 60 to the Ethernet ring 70 is carried out via an Ethernet switch or Ethernet switch 80.
- each Ethernet is -Switch 80 each formed by a 3-port switch.
- the internal structure of the 3-port switches can for example correspond to the structure as described in the published patent application DE 102 60 806 A1.
- the 3-port switches 80 each have - as the name implies - three ports. Two of the terminals are identified by the reference numeral A80 and serve to realize the ring structure of the Ethernet ring.
- the third connection S80 makes it possible to connect a device-internal device module or even the main CPU 20 to the Ethernet ring 70;
- the third port S80 may form an MII standard interface.
- the mode of operation of the Ethernet ring 70 according to FIG. 1 corresponds to the usual Ethernet standard, so that in this regard reference may be made to the relevant technical literature.
- the Ethernet ring 70 operates, for example, with a data rate of one gigabit / sec, and particularly preferably according to the pro fi net standard i-RTE.
- the 3-port switches 80 are each designed such that they operate according to the so-called cut-through method. This means that data transmitted via the ring are directly forwarded without caching unless they are intended for the respective device module; Such immediate forwarding without caching requires rapid processing of the incoming data, since the 3-port switches must check in real time which of the incoming data are relevant to their own device-internal device module and which are not.

It can be seen a DIN rail 100, on which the device modules 30, 40, 50, and 60 and the main CPU 20 are plugged.

- the device modules After the device modules have been plugged onto the DIN rail 100, they are pushed together along the longitudinal direction Z of the DIN rail 100 so that the network connections L110 / R110 in contact - optically or electrically - come and the Ethernet ring 70 is closed as shown in FIG. Specifically, for example, the right
- the main CPU 20 can also be applied to the
- DIN rail 100 attached and brought into connection with the device-internal modules 30 and 60 in connection.
- the ring line closing the Ethernet ring 70 which is identified by the reference numeral 200 in FIG. 1, may for example be integrated in the DIN rail 100. This is indicated schematically by a dashed line with the reference numeral 200 in FIG.
- the device-internal device modules may each be formed by a printed circuit board 210 on which one or more electronic components 220 such as microprocessor assemblies or the like are present.
- FIG. 3 shows an exemplary embodiment of an integrated electronic component 300, which may be, for example, an FPGA or ASIC module.
