---|---|
Abstract | The invention relates to a method for forming a device-specific information data record (N(j,i), T(j)) for use in a control station (30) to which it is possible to connect at least one electrical device (40a-40e) in an electrical installation (10), where the device-specific information data record relates to the connected electrical device (40a- 40e) and where device-specific information (0(j), TN(j)) prescribed by the user is taken into account when forming the device-specific information data record. The device-specific information data record is formed with the aid of a computer by reading a device template (TV(j), MV) associated with the connected electrical device from a database and taking a data subrecord (T1 (j), N(i)) from this device template, using the information (0(j), TN(j)) prescribed by the user as device-specific correction information and logically combining this correction information with the data subrecord (N(i), T1 (j)) with the aid of a computer, with the device-specific information data record being formed, and associating the device-specific information data record (N(j,i), T(j)) formed in this manner with the electrical device (40a-40e). |
Full Text | FIELD OF THE INVENTION The invention relates to a method for forming a device-specific information data record for use in a control station to which it is possible to connect at least one electrical device in an electrical installation, particularly a power supply installation, where the device-specific information data record relates to the connected electrical device and where device-specific information prescribed by the user is taken into account when forming the device-specific information data record. In this context, the term "electrical device" is intended to be understood to mean both single devices, such as protective or field devices, and groups or arrays of such single devices; in the latter case, the "electrical device" is thus formed by a plurality of single devices. BACKGROUND OF THE INVENTION By way of example, device-specific information data records for electrical devices need to be formed in the field of protection and control engineering for power supply installations. This will be explained below using prior art control stations, which are normally supplied for electrical control systems for power supply installations. Prior to startup, it is necessary to input into such a control station to what electrical devices (e.g. field devices, arrays of field devices, groups of field devices) the respective control station is connected or is to be connected, inter alia. It is also necessary to input the message numbers or slave addresses which are used to forward information (e.g. measured values) transmitted to the control station by the connected electrical devices to a control center which is superordinate to the control station. Comparably, besides the message numbers it is also necessary to input topology information for each device connected to the control station. In the case of the aforementioned prior art control station such device-specific information data records, which relate to message numbers (slave addresses) or topologies, need to be input manually; "assignment" of message numbers and topologies within the control station, as is also the specialist term for such input of device-specific information data records, is therefore relatively complex. OBJECT OF THE INVENTION The invention is based on the object of specifying a method for forming a device-specific information data record which gives rise to less complexity than the previously known manual method described. SUMMARY OF THE INVENTION The invention achieves this object by virtue of the device-specific information data record being formed with the aid of a computer by reading a device template associated with the electrical device from a database and taking a data subrecord from this device template. Information prescribed by the user is then used as device-specific correction information and logically combined with the data subrecord with the aid of a computer, which forms the device-specific information data record. The device-specific information data record formed in this manner is then associated with the electrical device. A fundamental advantage of the inventive method can be seen in that recourse is had to templates which are predefined for the devices (single devices or groups of devices); to generate the final device-specific information data record, it is then merely necessary to make a correction input in order to match the device template to the specific requirements in the individual case. By way of example, information data records for a control station can be formed in the manner described by forming, for each electrical device which is connected or to be connected to the control station, the information data record required for operation of the control station and storing it in the control station. By way of example, the control station is used to store one or more message numbers for a field device connected or to be connected thereto as a device-specific information data record, and the control station, when transmitting messages which originate from the field device, forwards these message numbers to a superordinate control center. Preferably, the data subrecord in this case contains a prescribed number of base numbers which have a single offset value added to them as correction information prescribed on a device-specific basis. It is also possible for the device-specific information data record associated with the electrical device to be topology information, for example, which defines a topological name for the electrical device within the installation. In this case, the data subrecord is preferably formed by a name component of the topological name of the device, with this name component having a device-specific supplementary name element added to it as correction information prescribed on a device-specific basis. Preferably, the data subrecord is formed by the last name component of the topological name, this last name component having the device-specific supplementary name element placed in front of it. The method described can also be used to operate an electrical installation having at least one field device, a control station which is superordinate to the field device and a control center which is superordinate to the control station, the control station having one or more message numbers associated with it - as described - for the field device. Measured data captured by the field device are then transmitted to the control station, which uses them to generate data telegrams and sends these to the control center. The data telegrams contain the received measured data from the field device and also the message number corresponding to the respective message. The invention is also considered to be a control station having a data processing installation which is programmed such that it can form a device-specific information data record - as described. The invention is also considered to be a computer program product which, following installation on a data processing installation, is suitable for carrying out a method - as described. The invention is explained in more detail below using an exemplary embodiment; in this context, by way of example: BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS Figure : 1 shows an arrangement with an inventive control station which is used to explain the inventive method by way of example, and Figure: 2 shows the control station from figure 1 in detail. DETAIL DESCRIPTION OF THE INVENTION In figure 1, it is possible to see a control system 10 for a power supply installation (which, for the sake of clarity, is not shown further) having a control center 20, a control station 30 which is subordinate to the control center and a multiplicity of field devices 40a, 40b, 40c, 40d and 40e, which are connected to connections E30a-E30e of the control station 30. By way of example, the field devices 40a-40e record measured values M relating to the power supply installation and transmit these measured values to the control station 30 on the basis of a master protocol. The control station 30 evaluates the . measured values M and uses the measured values M to generate, at its output A30, messages in the form of data telegrams D which are transmitted to the control center 20 using a slave protocol. The control center 20 is programmed such that for every message, that is to say for every piece of information and for every measured value M in a data telegram D, it expects a unique message number N. In this case, a message number N clearly indicates what type of information is involved and how this information is to be processed further. By way of example, the message number can indicate that the information is a measured value M and that the measured value M has been recorded by the field device 40a. Alternatively, the message number N may also indicate that the control station 30 itself has generated the corresponding information, for example by evaluating the measured values M from the field devices 40a-40e and hence forming separate evaluation information. It should be noted that each message number N should relate only to a single message type so that the control center 20 can process the incoming data telegrams D correctly. When assigning the information within the control station 20 - that is to say when stipulating what information is to be recorded and possibly combined and also forwarded - it is thus necessary to stipulate, within the control station 30, how the message numbers N are associated. In methods based on the prior art, described at the outset, message numbers N are input manually for each field device connected to the control station 30 on the basis of customer stipulations; by way of example, this means that with 500 message types it is necessary to define and input 500 respective message numbers for each of the field devices 40a-40e connected to the control station 30 in order to define the messages arising. To simplify such input, the exemplary embodiment of the invention which is described here has provision for a respective message number template MV (cf. figure 2) to be used for the field devices 40a-40e, which then receives only one field-device-specific offset value. By way of example, 500 base values N(l)-N(500) are firmly prescribed and defined in the message number template MV. During assignment of the message numbers within the control station 30, just one respective individual offset value 0(j) is then prescribed for each field device 40a-40e connected to the control station 30, said offset value being added to the base values stored in the message number template MV. In this context, "j" is meant to be a variable which clearly identifies the respective field device; by way of example, the following is meant to apply: j=l for field device 40a, j=2 for field device 40b, j=3 for field device 40c, j=4 for field device 40d, j=5 for field device 40e. The resultant field-device-specific message numbers N(j,l) to N(j,500) are then obtained through automatic addition within the control station 30 as follows: N(j, i) = N(i) + 0(j) where i = 1...500 and j = 1...4 By inputting a single offset value 0(j) per field device, it is thus possible to generate 500 individual message numbers as an information data record in a single work step. Unlike in the prior art, it is therefore not necessary to input 500 respective message numbers manually for each field device 4 0a- 4 0e; instead, these are generated automatically by inputting a single offset value 0(j) per field device and by subsequent addition by computer within the control station 30. Accordingly, a respective topological name T(j) may also be associated with the field devices 40a-40e in the control station 30 as an information data record. Within the topological name or tree, it is possible to create a voltage level below the control station 30, a field below the voltage level and a user-defined group below the field, for example. The resultant topological name T(j) then has the following form, for example: T(j) = When inputting a topological name of this kind, a respective device template is used in the form of a topology template TV(j) for each of the field devices 40a-40e, in which previously defined and stored values Value(j) for the last component of the name, for example, Tl(j) = are firmly prescribed as data subrecord Tl(j). To define the full topological name T(j) during assignment of the topology within the control station 30, it is then merely necessary to input the first element, in this case that is to say the name of the control station, the name of the voltage level, the name of the field and the name of the user-defined group, for example, as device-specific or field-device-specific supplementary name element TN(j). The control station 3 0 then forms the full topological name T(j) automatically by placing the field-device-specific supplementary name element TN(j) = in front of the predefined component T1(j)= T(j) = TN(j) + T1(j) Figure 2 shows an exemplary embodiment of the control station 30 shown in figure 1. It is possible to see an internal data processing installation 100 into which it is possible to input device-specific topology templates TV(j), device-specific supplementary name elements TN(j), a cross-device (for example device-type-specific) message number template MV and also device-specific offset values 0(j). The data processing installation 100 then automatically ascertains, by addition, the resultant device-specific message numbers N(j,l) to N(j,500) as follows: N(j , i) = N(i) + 0(j) and stores these in its memory 110. In addition, it forms the full topological names T(j) for the field devices 40a-40e by assembling the components T1(j) and TN(j), as was described in connection with figure 1, as follows: T(j) = TN(j) + T1(j) and stores these in its memory 110. In the exemplary embodiment shown in figure 2, the message number template MV and the topology templates TV(j) are input into the control station 3 0 via the connection S3 0; alternatively, they may also be stored in a database in the memory 110, so that input is not necessary. By way of example, the message number template MV and the topology templates TV(j) may have been permanently preinstalled in the memory 110. WE CLAIM 1.
