Abstract

An offset printer has a number of computer controlled stations Ä1.1-1.5Ü which are interconnected via an optical fibre bus cable Ä2Ü. Each station has a bus coupler Ä3Ü having a transmitter Ä3.1Ü and a receiver Ä3.2Ü to exchange information with other stations. The transmitter stages are coupled to a control and analyser unit Ä4Ü that controls the power of the optical devices. At system start up the transmitter power is increased in a number of steps until a level is reached that is appropriate for signal transmission.

Description

Die Erfindung betrifft ein Bussystem für eine Druckmaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to a bus system for a printing press according to the preamble of claim 1.

Bei Bogenoffsetdruckmaschinen ist es, wie schon seit langem bei großen Rollenrotationsdruckmaschinen bekannt, in den einzelnen Einheiten Stationen in Form vom Rechnern anzuordnen und diese mittels einem Bus miteinander zu verbinden. So ist beispielsweise aus der EP 0 543 281 Al eine Steuerung für Rotationsdruckmaschinen bekannt, bei welcher jedem Anlagenteil ein oder mehrere Rechner-Einheiten zugeordnet sind und diese Einheiten über einen Koax- bzw. verdrillten Zweidrahtleiter-Bus miteinander verbunden sind. So ist es möglich, daß beispielsweise von einer Master-Station, über welche die gesamte Steuerung der Druckmaschine erfolgt, Kommandos in Form von Bussignalen an die einzelnen Rechner-Einheiten in den jeweiligen Aggregaten gesendet werden. Die einzelnen Einheiten, welche beispielsweise mit Sensoren oder sonstigen Erfassungseinrichtungen verbunden sind, können ebenfalls Signale an die Master-Station zurücksenden. Ebenfalls kann vorgesehen sein, daß keiner der Rechner-Einheiten einen Master darstellt, sondern daß sämtliche Rechner-Einheiten autark und gleichberechtigt nötige Information in Form von Signalen senden und empfangen können.In sheet-fed offset printing presses, as has long been known for large web-fed rotary printing presses, it is necessary to arrange stations in the form of computers in the individual units and to connect them to one another by means of a bus. For example, a control for rotary printing presses is known from EP 0 543 281 A1, in which one or more computer units are assigned to each system part and these units are connected to one another via a coax or twisted two-wire bus. It is thus possible, for example, for commands to be sent in the form of bus signals to the individual computer units in the respective units from a master station via which the entire control of the printing press takes place. The individual units, which are connected, for example, to sensors or other detection devices, can likewise send signals back to the master station. It can also be provided that none of the computer units represents a master, but that all computer units can send and receive necessary information in the form of signals independently and with equal rights.

Aus der DE-Z der Polygraph, 9/86, Seite 1103 und 1104 ist es ferner bekannt, die in den einzelnen Druckwerken angeordneten Mikroprozessoren über ein Verbundnetzt aus Glasfaserkabeln untereinander und mit dem Fernsteuerpult der Druckmaschine zu verbinden. Der Vorteil der Glasfasertechnik als Bussystem liegt dabei darin, daß eine größtmögliche Datenübertragungsrate bei völliger Immunität gegenüber elektrischen Störeinflüssen gegeben ist.From DE-Z of Polygraph, 9/86, pages 1103 and 1104 it is also known to connect the microprocessors arranged in the individual printing units to one another and to the remote control panel of the printing press via a composite network of fiber optic cables. The advantage of fiber optic technology as a bus system lies in the fact that the highest possible data transmission rate is given with complete immunity to electrical interference.

Bei Installations- und insbesondere Servicearbeiten kommt es aber immer wieder vor, daß die Verbindungen der einzelnen Stationen mit dem Bus gelöst bzw. wieder hergestellt werden müssen. Dabei kann es passieren, daß elektrische und/oder optische Verbindungen (Steckverbindungen) nicht ordnungsgemäß hergestellt werden. Bei elektrischen Steckverbindungen kann beispielsweise ein nicht vollständiges Aufstecken oder das Einbringen von Verunreinigungen in den Steckverbinder dazu führen, daß die derartig mit dem Bus verbundene Station keine ordnungsgemäße Signalankopplung an den Bus erfährt. Für eine bestimmte Zeit kann dabei trotzdem noch ein Signaltransfer zwischen Bus und jeweiliger Station stattfinden, es liegt dann aber eine potentielle Fehlerquelle vor, welche auch durch übliche und bekannte Bustests mittels Signalroutinen und dgl. zu nicht vorhersehbaren plötzlichen Ausfällen führen kann.During installation and in particular service work, however, it often happens that the connections of the individual stations to the bus have to be disconnected or re-established. It can happen that electrical and / or optical connections (Plug connections) are not properly established. In the case of electrical plug connections, for example, an incomplete plugging in or the introduction of contaminants into the plug connector can result in the station connected in this way to the bus not being properly coupled to the bus. A signal transfer can still take place between the bus and the respective station for a certain time, but there is then a potential source of error, which can also lead to unpredictable sudden failures through conventional and known bus tests using signal routines and the like.

Bei Installations- und Servicearbeiten werden die das Bussystem darstellenden Leitungen oftmals in nicht vorschriftsgemäßer Weise belastet. So kann es vorkommen, daß das Kabel eines Lichtwellenleiters oder eines Koax-Leiters zu stark gekrümmt bzw. geknickt wird. Auch kann es durch Ziehen von Kabeln, insbesondere durch enge, scharfkantige Öffnungen zu einer Beschädigung der Isolations- bzw. Schutzummantelungen kommen. Derartigen Schadensmöglichkeiten sind dabei auch verdrillte Zweitdrahtleiterbusse ausgesetzt.During installation and service work, the lines that represent the bus system are often loaded in an improper manner. It can happen that the cable of an optical waveguide or a coax conductor is bent or bent too much. Pulling cables, in particular through narrow, sharp-edged openings, can also damage the insulation or protective sheathing. Such types of damage are also exposed to twisted-pair wire buses.

Die oben beschriebenen Beschädigungs- oder Fehlbehandlungsmöglichkeiten stellen ebenfalls eine potentielle Fehlerquelle dar. Auch hier ist bei bekannten Bussytemen ein plötzlicher Signalausfall nicht vorhersehbar.The damage or incorrect handling options described above also represent a potential source of error. Here, too, a sudden signal failure cannot be foreseen in known bus systems.

Neben unsachgemäßen Handhabungen an dem Busleitungssystem können ferner gerade bei Koax- bzw. verdrillten Zweidrahtleiterbussen Störfelder zu einer Herabsetzung der Übertragungskapazität, wenn nicht gar zum totalen Übertragungsausfall des jeweiligen Bussystems führen. Hier seien beispielsweise magnetische oder kapazitive Einkopplungen von Starkstromleitungen, Überkopplung benachbarter Leitungen und Ströme in Abschirmungsleitungen genannt. Derartige Störungen stellen ebenfalls eine starke Beeinträchtigung des Bussystemes dar, wozu es insbesondere dann kommt, wenn Leitungen insbesondere bei Serviceleitungen nicht ordnungsgemäß verlegt werden und in zu enge Nachbarschaft mit anderen Leitungssystemen gelangen. Auch Alterungen in Bauteilen, insbesondere bei optoelektronischer Signalübertragung, stellen eine potentielle Fehlerquelle dar.In addition to improper handling of the bus line system, interference fields can also lead to a reduction in the transmission capacity, if not to a total transmission failure of the respective bus system, especially in the case of coax or twisted two-wire bus. Magnetic or capacitive couplings of power lines, coupling of neighboring lines and currents in shielding lines may be mentioned here, for example. Such faults also represent a severe impairment of the bus system, which occurs in particular when lines, particularly in the case of service lines, are not routed properly and come into close proximity with other line systems. Aging in components, particularly with optoelectronic signal transmission, is also a potential source of errors.

Bei Glasfaserkabeln und Lichtwellenleitern ist es bekannt, deren Funktionssicherheit hinsichtlich der Signalübertragung über die Messung der optischen Dämpfung zu erfassen.In the case of glass fiber cables and optical fibers, it is known to determine their functional reliability with regard to signal transmission by measuring the optical attenuation.

Dazu ist es aber nötig, die zusammenhängenden Enden in der Leitung von der jeweiligen Station zu lösen und an ein spezielles Meß- und Diagnosegerät anzuschließen. Bei dem nachfolgenden Anschließen der zusammenhängenden Enden einer Leitung an die Einheiten kann es dabei wegen der nötigen Handhabungen ebenfalls zu potentiellen Fehlerquellen führen, wenn insbesondere die optische Ankoppelung zwischen Leiterende und der dazugehörigen Optoelektronik nicht vollständig und einwandfrei hergestellt wird. Weist die Optoelektronik einer Station dabei mehrere und auch freie Eingänge auf, so ist ferner auch ein Fehlstecken bei der Wiederherstellung der Lichtwellenleiterverbindung möglich.To do this, however, it is necessary to disconnect the connected ends in the line from the respective station and to connect them to a special measuring and diagnostic device. When the connected ends of a line are subsequently connected to the units, the necessary handling can also lead to potential sources of error if, in particular, the optical coupling between the end of the conductor and the associated optoelectronics is not completely and correctly produced. If the optoelectronics of a station have several and also free inputs, it is also possible to insert them incorrectly when restoring the optical fiber connection.

Aufgabe der vorliegenden Erfindung ist es daher, ein Bussystem gemäß dem Oberbegriff von Anspruch 1 derartig zu erweitern, so daß bei einfacher Ausgestaltung die oben genannten Nachteile vermieden und Veränderungen in der Übertragungskapazität des Bussystems frühestmöglich erkannt werden können.The object of the present invention is therefore to expand a bus system in accordance with the preamble of claim 1 such that, with a simple design, the disadvantages mentioned above are avoided and changes in the transmission capacity of the bus system can be detected as early as possible.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen. Der Begriff Bus bzw. Bussystem wird hierbei auch für Übertragungsleitungen verwendet, bei denen eine Datenübertragung jeweils zwischen benachbarten Stationen nach Art einer Loop erfolgt.This object is achieved by the characterizing features of claim 1. Further developments of the invention result from the subclaims. The term bus or bus system is also used here for transmission lines in which data is transmitted between neighboring stations in the manner of a loop.

Erfindungsgemäß ist vorgesehen, daß wenigstens eine der an das Bussystem angekoppelten Stationen einen Buskoppler aufweist, der von Zeit zu Zeit bzw. bei jedem Einschalten des Bussystems (Power-On) eine Signalfolge zwecks Aufbau einer Verbindung mit der oder den anderen Stationen auf das Bussystem sendet, wobei diese Signalabgabe durch den Buskoppler in einer Weise erfolgt, daß wenigstens eine physikalische Größe des dem Bussystem zugrunde liegenden Leitungsprotokolls außerhalb eines vorgesehenen Rahmens liegt. Dies kann insbesondere bei Lichtwellenleitern in einer Weise erfolgen, daß z.B. eine Master-Station bei einem Power-On, also dem Einschalten der Druckmaschine nebst Steuerung, über das Bussystem mit den anderen Stationen eine Verbindung mit geringer Sendeleistung aufzubauen versucht. Dabei kann insbesondere vorgesehen sein, daß die eine Station diese Verbindungsaufnahme mit sukzessiv steigender Sendeleistung wiederholt. Erst wenn sämtliche angesprochenen Stationen den Verbindungsaufbau ordnungsgemäß quittieren - die Quittierung erfolgt in zweckmäßiger Weise auf dem gemäß Leitungsprotokoll vorgesehenem Sendeleistungsniveau -, schaltet der Buskoppler der vorgesehenen Station auf die vorgesehene Sendeleistung um und es erfolgt im fehlerfreien Fall der normale Sendebetrieb. Durch das sukzessive Erhöhen der Sendeleistung beim Versuch Verbindungen zu den übrigen Stationen aufzubauen ist es möglich, festzustellen, welche minimale Sendeleistung die Busleitung benötigt um eine ordnungsgemäße Datenübertragung gerade noch zu ermöglichen. Es ist somit die Differenz zwischen der normalen Sendeleistung gemäß Leitungsprotokoll und der derartig ermittelten Minimalsendeleistung bildbar, woraus ein Maß für die Systemreserve abgeleitet werden kann.According to the invention it is provided that at least one of the stations coupled to the bus system has a bus coupler which from time to time or each time the bus system is switched on (power-on) sends a signal sequence for the purpose of establishing a connection with the other station or stations to the bus system , wherein this signal output by the bus coupler takes place in such a way that at least one physical quantity of the line protocol on which the bus system is based lies outside an intended frame. This can be done in particular in the case of optical fibers in such a way that, for example, a master station tries to establish a connection with low transmission power with the other stations via the bus system during a power-on, that is to say when the printing press and the control system are switched on. It can in particular be provided that the one station repeats this connection establishment with successively increasing transmission power. The bus coupler only switches the intended one when all the addressed stations properly acknowledge the connection establishment - the acknowledgment is expediently carried out at the transmission power level provided in accordance with the line protocol Station to the intended transmission power and normal transmission takes place in the fault-free case. By gradually increasing the transmission power when trying to establish connections to the other stations, it is possible to determine which minimum transmission power the bus line requires in order to enable proper data transmission. The difference between the normal transmission power according to the line protocol and the minimum transmission power determined in this way can thus be formed, from which a measure of the system reserve can be derived.

Eine wie eingangs beschrieben zustandegekommene Fehlerquelle wird aber in der Regel bewirken, daß die Differenz zwischen der normalerweise vorgesehenen Sendeleistung und der gerade noch zum Zustandekommen eines Verbindungsaufbaues minimal benötigten Sendeleistung deutlich geringer wird. Durch den erfindungsgemäß gestalteten Buskoppler ist dies feststellbar und kann beispielsweise zur Anzeige eines entsprechenden Warnhinweises oder gar zum Auslösen eines Systemabbruchs mit einem Sperren des Druckmaschinenantriebs gegen ein Anlaufen genutzt werden.However, an error source which has arisen as described at the outset will generally have the effect that the difference between the transmission power normally provided and the transmission power which is just minimally required to establish a connection is markedly smaller. This can be determined by the bus coupler designed according to the invention and can be used, for example, to display a corresponding warning or even to trigger a system shutdown by blocking the printing press drive against starting.

Das erfindungsgemäße Prinzip ist dabei nicht nur zur Verwendung bei Bussystemen beschränkt, welche Glasfaserkabel bzw. Lichtwellenleiter aufweisen. Auch muß nicht die Sendeleistung, mit der eine Station den Verbindungsaufbau zu anderen Stationen versucht, variiert werden, sondern es können auch andere physikalische Größen im vom Leitungsprotokoll abweichender Weise verwendet werden. Erfindungsgemäß können potentielle Busfehlerquellen auch dadurch ermittelt werden, indem der Verbindungsaufbau mit abweichender Sendefrequenz, mit einer anderen als vorgesehenen Bandbreite, unter bewußter Hinzumischung von Neben- oder Störfrequenzen und dgl. durchgeführt werden. Auch hier ist das Kriterium zur Ermittlung der Systemreserve das Variieren einer physikalischen Sendegröße, also bei welchem Wert der Wert der variierten physikalischen Größe ein ordnungsgemäßer Verbindungsaufbau zwischen den Stationen zustande kommt.The principle according to the invention is not only limited for use in bus systems which have glass fiber cables or optical fibers. Also, the transmission power with which a station tries to establish a connection to other stations does not have to be varied, but other physical variables can also be used in a manner that differs from the line protocol. According to the invention, potential bus error sources can also be determined by carrying out the connection establishment with a different transmission frequency, with a bandwidth other than the intended one, with deliberate addition of secondary or interference frequencies and the like. Here, too, the criterion for determining the system reserve is the variation of a physical transmission variable, that is to say at which value the value of the varied physical variable is able to establish a proper connection between the stations.

Sind die Übertragungsleitungen des Bussystems als sogenante Loop ausgebildet, bei der die Daten von einer Station zu jeweils einer benachbarten Station weitergeleitet werden, so weist jede Station einen erfindungsgemäßen Buskoppler auf Geprüft werden dann die Übertragungsleitungen zwischen benachbarten Stationen.If the transmission lines of the bus system are designed as a so-called loop, in which the data are forwarded from one station to an adjacent station, each station has a bus coupler according to the invention. The transmission lines between adjacent stations are then checked.

In einer als Bus im eigentlichen Sinne ausgebildeten Übertragungsleitung reicht es, daß lediglich eine Station einen entsprechend steuerbaren Buskoppler zur Variation wenigstens einer physikalischen Sendegröße aufweist.In a transmission line designed as a bus in the actual sense, it is sufficient that only one station has an appropriately controllable bus coupler for varying at least one physical transmission variable.

Des weiteren erfolgt die Erläuterung eines Ausführungsbeispiels der Erfindung anhand der Zeichnungen. Es zeigt:

Fig. 1 zeigt die Druckwerke einer Bogenoffsetdruckmaschine. Den einzelnen Druckwerken sind als Rechner ausgebildete Stationen 1.1 bis 1.5 zugeordnet, welche über einen gemeinsamen und als Lichtwellenleiter ausgebildeten Bus 2 in Signalverbindung miteinander stehen.Fig. 1 shows the printing units of a sheet-fed offset printing machine. The individual printing units are assigned stations 1.1 to 1.5 designed as computers, which are in signal connection with one another via a common bus 2 designed as an optical waveguide.

Eine Station 1.1 weist, wie die übrigen Stationen 1.2 bis 1.5 (dort nicht dargestellt), einen Buskoppler 3 auf, der aus einem Sende- 3.1 und Empfangsteil 3.2 besteht. Über den Sende- 3.1 und Empfangsteil 3.2 erfolgt das Senden und Empfangen von Signalen des Busses 2 an und von den übrigen Stationen 1.2 bis 1.5.A station 1.1, like the other stations 1.2 to 1.5 (not shown there), has a bus coupler 3, which consists of a transmitter 3.1 and receiver 3.2. The transmitting and receiving parts 3.2 are used to send and receive signals of the bus 2 to and from the other stations 1.2 to 1.5.

Der Sendeteil 3.1 des Buskopplers 3 der Station 1.1 steht mit einer Steuer- und Auswerteeinheit 4 in Wirkverbindung, so daß auf dem Bus 2 über die Optoelektronik des Buskopplers 3 Sendesignale mit unterschiedlicher Signalleistung abgegeben werden können. Der Sendeteil 3.1 weist dazu einen in der Lichtleistung steuerbaren Lichtsender auf. Über die Steuer- und Auswerteeinheit 4 erfolgt die Festlegung, mit welcher Leistung der Lichtsender die optischen Signale in den Lichtwellenleiter einspeist.The transmitting part 3.1 of the bus coupler 3 of the station 1.1 is in operative connection with a control and evaluation unit 4, so that 3 transmission signals with different signal power can be emitted on the bus 2 via the optoelectronics of the bus coupler. For this purpose, the transmitting part 3.1 has a light transmitter that can be controlled in terms of light output. The control and evaluation unit 4 determines the power with which the light transmitter feeds the optical signals into the optical waveguide.

Erfindungsgemäß ist nun vorgesehen, daß bei einem Power-On - dazu steht die Steuer- und Auswerteeinheit 4 mit einer nicht dargestellten Spannungsversorgung der Druckmaschine in Wirkverbindung - über den Sendeteil 3.1 des Buskopplers 3, gesteuert durch die Steuer- und Auswerteeinheit 4, ein Signal zur Verbindungsaufnahme mit ein oder mehreren der übrigen Stationen 1.2 bis 1.5 mit verminderter und danach steigender Sendeleistung wiederholt abgegeben wird.According to the invention, it is now provided that during a power-on - for this purpose the control and evaluation unit 4 is in operative connection with a voltage supply of the printing press, not shown - via the transmitting part 3.1 of the bus coupler 3, controlled by the control and evaluation unit 4, a signal for Establishing contact with one or more the other stations 1.2 to 1.5 with reduced and then increasing transmission power is repeatedly delivered.

Fig. 2 zeigt ein Zeitdiagramm, nach welchem die Steuer- und Auswerteeinheit 4 über den Sendeteil 3.1 des Buskopplers 3 die Sendeleistung zur Aufnahme einer Verbindung mit den übrigen Stationen 1.2 bis 1.5 schrittweise erhöht. Im Zeitdiagramm der Fig. 2 ist dabei mit Pn die Sendeleistung des normalen Signalaustausches gekennzeichnet. In diesem Beispiel sendet der Sendeteil 3.1 des Buskopplers 3 insgesamt drei mal Signale zur Verbindungsaufnahme mit einer Sendeleistung P, welche jeweils kleiner ist als die normalerweise vorgesehene Sendeleistung Pn. Unter der Signalabgabe zum Aufbau einer Verbindung mit den übrigen Stationen 1.2 bis 1.5 ist bei dem Lichtwellenleiter des Busses 2 als seriellen Bus eine bestimmte Bit-Folge zu verstehen. Die Erhöhung der Sendeleistung P wird dabei von Signalabgabe zu Signalabgabe schrittweise bis auf den vorgesehenen Sendeleistungswert Pn erhöht.2 shows a time diagram, according to which the control and evaluation unit 4 gradually increases the transmission power to establish a connection with the other stations 1.2 to 1.5 via the transmission part 3.1 of the bus coupler 3. In the time diagram of FIG. 2, the transmission power of the normal signal exchange is identified by Pn. In this example, the transmitting part 3.1 of the bus coupler 3 sends a total of three times signals for establishing a connection with a transmission power P which is in each case smaller than the normally provided transmission power Pn the bus 2 to understand a certain bit sequence as a serial bus. The increase in transmission power P is gradually increased from signal output to signal output up to the intended transmission power value Pn.

Im unter dem Zeitdiagramm der Fig. 2 dargestellten Zeitdiagramm der Fig. 3 ist wiedergegeben, daß erst zu einem Zeitpunkt T1 einer der Stationen 1.1 bis 1.5 die Signalfolge zwecks Verbindungsaufbau erkannt und entsprechend mit voller Sendeleistung an die Sendestation 1.1 zurückgeschickt hat. In der mit dem Buskoppler 3 in Wirkverbindung stehenden Steuer- und Auswerteeinheit 4 ist somit ein Antwort signal A generierbar, welches hier beispielhaft zu verstehen von 0 auf 1 wechselt, wenn von einer oder mehrerer der Stationen 1.1 bis 1.5 der ordnungsgemäße Verbindungsaufbau quittiert worden ist. Die Stationen 1.2 bis 1.5 müßen zur Quittierung des korrekten Verbindungsaufbaues nicht die mit verminderter Sendeleistung gesendeten Signale wieder an die Station 1.1 zurücksenden, sondern es ist auch möglich, daß das Quittieren des korrekten Verbindungsaufbaues durch eine vorgegebene Signal- bzw. Bit-Folge erfolgt.The time diagram of FIG. 3 shown under the time diagram in FIG. 2 shows that only at time T1 one of the stations 1.1 to 1.5 recognized the signal sequence for the purpose of establishing a connection and accordingly sent it back to the transmitting station 1.1 with full transmission power. A response signal A can thus be generated in the control and evaluation unit 4 which is operatively connected to the bus coupler 3 and which, here to be understood as an example, changes from 0 to 1 when the correct connection establishment has been acknowledged by one or more of the stations 1.1 to 1.5. Stations 1.2 to 1.5 do not have to send the signals sent with reduced transmission power back to station 1.1 to acknowledge the correct connection establishment, but it is also possible for the correct connection establishment to be acknowledged by a predetermined signal or bit sequence.

Da die mit dem Buskoppler 3 der Station 1.1 in Wirkverbindung stehende Steuer- und Auswerteeinheit 4 schrittweise die Sendeleistung P erhöht hat und ferner durch die Steuer- und Auswerteeinheit 4 über den Empfangsteil 3.2 des Buskopplers 3 feststellbar ist, zu welchem Zeitpunkt also bei welcher Sendeleistung P von einer der Stationen 1.2 bis 1.5 der korrekte Verbindungsaufbau quittiert wurde, ist nun feststellbar, wie groß die Differenz zwischen normalerweise vorgesehenen Sendeleistung Pn und der minimal nötigen Sendeleistung für einen ordnungsgemäßen Datenverkehr ist. Aus dieser Leistungsdifferenz ist sodann ein Gütewert bildbar, aus dem hervorgeht, wie groß die Leistungsreserve des Bussystems ist. Unterschreitet diese zuvorstehend definierte Leistungsdifferenz einen vorgegebenen Grenzwert, so kann vorgesehen sein, einen Warnhinweis anzuzeigen und/oder den Antrieb der Druckmaschine gegen ein Anfahren zu sperren.Since the control and evaluation unit 4, which is operatively connected to the bus coupler 3 of the station 1.1, has gradually increased the transmission power P and can also be determined by the control and evaluation unit 4 via the receiving part 3.2 of the bus coupler 3, at which point in time at which transmission power P The correct connection establishment has been acknowledged by one of the stations 1.2 to 1.5, it can now be determined how large the difference between the normally provided transmission power Pn and the minimum required Is transmission power for proper data traffic. A quality value can then be formed from this power difference, which shows how large the power reserve of the bus system is. If this previously defined performance difference falls below a predetermined limit value, it can be provided to display a warning and / or to block the drive of the printing press against starting.

Im obigen Ausführungsbeispiel wurde die Erfindung an einem eigentlichen Bus bzw. Bus-system erläutert. Lediglich eine Station 1.1 weist den erfindungsgemäß ausgebildeten Buskoppler 3 auf. Ist der Bus als Loop ausgebildet, so weist jede der vorhandenen Stationen 1.1 - 1.n den erfindungsgemäßen Buskoppler 3 auf, so daß jeweils eine Überprüfung der Übertragungsleitungen zwischen zwei benachbarten Stationen erfolgt. Der zuvor beschriebene Ablauf ist dabei aber der gleiche.In the above exemplary embodiment, the invention was explained on an actual bus or bus system. Only one station 1.1 has the bus coupler 3 designed according to the invention. If the bus is designed as a loop, each of the existing stations 1.1-1n has the bus coupler 3 according to the invention, so that the transmission lines between two neighboring stations are checked in each case. The procedure described above is the same.
