Method and apparatus for configuration of a computerized system,

The invention relates to a method for detecting the configuration of a computer-aided system, in particular a high performance printer, in which a central controller via a communications bus having a plurality of manner of a chain cascaded control modules is connected. Further, the invention relates to a system employing this method. The invention can be in the form of computer program elements used.

The special features of a computerized system with different hardware components generally designated configuration. The configuration there is information as to which components the entire system is equipped and which components TRE interact th can. The configuration includes configuration data, based on which the system can identify which components are actually present and can be done under which address with them traffic.

Conventional computerized systems are configured only in the production. The user of such a system can carry out only with considerable restrictions subsequent changes. This disadvantage occurs particularly in high-performance printing systems is clear. The mechanical and electronic components of such high-performance printing systems have a one-time on the part of the manufacturer and thus set the configuration; later changing the arrangement of the various components and a new configuration is possible by the user only with great effort. From DE-C 44 07 895, an information data network is known which includes a plurality of network nodes. The network nodes activate each other mutually in order to stuffs to übermit- from a central computer their respective node identifier.

From DE-A-196 49 676 describes a system with a central unit and several peripheral units is known, which addresses are supplied from the central processing unit. For this purpose, a ste ER signal line is provided, is produced with the parallel connection (bus connection) between the central unit and the peripheral units. A second data line, a cascade connection between the central unit and the peripheral units is prepared. For this purpose, the central processing unit is to be serially connected to the first peripheral unit, to which in turn the following peripheral units are connected serially.

It is an object of the invention to provide a method and Einrich- tung which a change in the structure of the components compilation allows in a simple manner, automatically to recognize the newly formed configuration, and the configuration data are acquired.

This object is inventively achieved by a method for detecting the configuration of a computer-aided system, in particular a high performance printer, in which a central controller via a communications bus having a plurality of manner of a chain cascaded tax it is connected odulen, each control module holds identification data, by the central control and / or the further control modules identify it, the central controller via the communication bus, all control modules requests using a multiple contact information, send trainees identification data, the control modules are connected by an identification line with each other, all the control modules are connected passively in a preparatory phase, in which they will send out request for identification no identification data, each control module upon receipt of a separate identification signal, and after its request for identification Identifikationsd ata emits again switched to the passive state and emits the identification signal on the identification line to the adjacent control module, the in-chain at the end of control module first receives the identification signal and wherein said central controller upon receipt of the respective identifica- onsdaten a assigns configuration address for the respective control module, with which it can be addressed by the central control or of the other control modules.

In the invention, the various control modules are arranged in the manner of a chain or "party-line". The control modules give gradually according to their arrangement in the chain identification data from which enable accurate correlation and addressing via the communication bus. Since the identification data are given off in the order of arrangement, also the place of the respective control module within the chain is known. The central controller contains a list of all possible control modules and can make an accurate mapping of these control modules and their identification data to this list. In this way, the central controller and, optionally, also the other control modules able to uniquely identify all of the control modules within the chain and communicate if necessary with them.

that the configuration of control modules is detected automatically by the invention is achieved. The user can compose a complex system with a plurality of control modules themselves, without having to have detailed knowledge of the system, because the system can recognize the configuration change automatically. The invention can be advantageously used in a variety of systems, especially in systems whose control modules must be assembled for specific applications, for example in computerized systems in industrial plants, in lifts, etc .. In particular, there are advantages when used in a high-capacity printing system, wherein each the requirement of pressure there are various combinations of hardware stations.

A preferred embodiment of the invention is characterized in that the central control unit after a predetermined waiting period in which no identification data is output to the communication bus to a request for identification, the emission of the request for identification breaks off. By this measure, an end criterion is defined, upon the occurrence of the Selbstkonfigu- ration is complete and the central controller assumes its other control tasks, which are responsive, the control modules in accordance with the determined configuration information.

According to a further aspect of the invention is provided a system according to claim 3, which implements said process substantially. The beneficial effects mentioned imagine a well in the inventive system.

Embodiments of the invention are explained below with reference to the drawing. In this drawing shows

1 shows a high-performance printer system with multiple

stations

2 shows a general example of a computer-aided system to a communication bus to which several control modules are connected,

3 shows method steps for self-configuration of the system according to Figure 2 and Figure 4 a of Figure 2 corresponding system, which is expanded by an additional identification line.

Figure 1 schematically shows a high-performance printer system having a central printer unit, which also contains the central control in general. On the input side the Druk- kereinheit can be connected to various input units A, B, C. These input devices A, B, C, for example, can differ in the nature is to be printed on paper, for example, various sheet formats, folded paper or paper from a roll, which is cut later after printing to the required length format. In the present case, the high performance printer system is configurable riert that the input unit B is input connected to the kereinheit Druk-.

The output side, a staple unit D, a folding unit E, a sorting unit F and / or a punching unit G may be connected to the printer unit, depending on the further processing of the printed paper. In this case, the sorting unit F is connected, that is, the printed paper is sorted in the sorting unit F into bundles.

Similarly to the high-performance printer system different output devices H, I be connected. In this case, the output unit I is connected.

In the case shown in Figure 1 under a variety of configurations is shown, which connects the central Druk- kereinheit with the units B, F and I. It is easy to understand that a user wants to create different configurations depending on the application, without having to perform complex operations to inform a central control of the selected configuration and the necessary configuration data. The units shown in Figure 1 A to I are denoted in the following consideration of a general embodiment of the control modules.

Figure 2 shows a general embodiment in which a central control ZST via a communication bus BUS in the manner of an open chain, which is also referred to as a party line, with different control modules STML, STM2 is connected STM3. As a communication bus, a data bus CAN (Controller Area Network) or used V.24 can, for example according to the standard SDLC (Serial Data Link Communica- tion). Each control module (STML, STM2, STM3) has an input terminal next to his terminal for the communication bus BUS IS-SET for an identification signal IS as well as a starting terminal OUT IS-IS for the identification signal. The output terminal IS OUT is connected to the input terminal INPUT of the IS-adjacent in the chain of control modules control module by an identification line IL. For example, the output terminal OUT of the control module IS STM3 on the identification line IL is connected to the input terminal INPUT of the IS-control oduls STM2. As identification signal IS a fixed potential, for example, be used which results from a constant current flowing through a resistor R to ground. The connection of the control modules STML, STM2, STM3 therefore takes place to a par- allel through the communication bus BUS and to the other in series by the ID lines IL.

For the realization of the connections among the control modules STML, STM2, STM3 and the connection via the communication bus BUS to the central controller ZST is provided that each control module STML, STM2, STM3 has a multi-pole connector output. A group of male contacts is reserved for the communication bus BUS. A plug connection is then used as an input terminal IS-INPUT and another male terminal serves as the output terminal IS OUT. The central controller ZST and the control modules STML, STM2, STM3 are then connected by a plurality of connecting cables in the manner of an open chain, each having two pin outs of the control modules STML, STM2, STM3 connect with each other. The connecting cables are then looped through control module to control module. The plug of the cable to which it is in the chain at the end STE rising control module STM3 connected, then the circuitry shown in Figure 2, according to which the active signal level for the identification signal IS is generated at the resistor R.

Each control module includes a control logic SL, which interprets the communication protocol of the bus BUS, controls the identification sequence within the module and is connected by means of a switch capable of a conductive connection between the terminals ϊS-INPUT and the manufacturer determine IS OUT of the module or to separate.

A suitable CAN bus system for a high performance printing system is described in WO-A-97 / 16,771th The content of this publication is hereby incorporated by reference into the vorlie- restrictive description.

Figure 3 illustrates in flow chart form, process steps for the self-configuration. The self-configuration is performed in each case when the power returns. According to step 10, after switching on the operating voltage to the step 12 branches, in which initializes the central controller in a preparation phase and all of the control modules STML, STM2 are switched STM3 passive. This means that the control modules STML, STM2, STM3 be addressed via a common collecting address, and notifying them that they must not send identification data to request for identification, that are switched to passive (step 14, first part). The in-chain at the end of control module STM3 has the identification signal IS applied at its input terminal IS-SET (step 14, second part). In the following step 16, the central controller via the communication bus ZST and speaks for all control modules STML, STM2, STM3 common bus address these control modules and asks them to delivery of identification data. The control modules STML, STM2, STM3 (SL1, SL2, SL3) are provided, which allows them to only deliver identification data when the identification signal IS is applied to its respective input terminal IS-INPUT and if they are not already identification in each case with an internal control logic - has data issued in accordance with step 18th This control logic is generally implemented by a microprocessor executing the instructions of a control program. Initially, only the in-chain end control module STM3 has applied this identification signal -IS, ie, the control module STM3 transmits its identification data pass via the communication bus BUS for central control ZST. There is a list of all conceivable configuration for a possible control modules. The control module STM3 is accepted in accordance with this description and it is assigned a rationsadresse configurations under which it can be addressed in future by the central control ZST and from the other control modules (step 18).

In the following step 20, the control module STM3 sets its output terminal IS OUT from "0" to "1", ie, there is on the identification line IL, the identification signal IS to the subsequent in the sequencer control module (step 20). Furthermore, the control module STM3 outputs a message through the communication bus BUS to the central controller that it has passed the identification signal (step 22, first part). In addition, the internal control logic of the control module STM3 is adjusted so that it does not respond to further requests for the delivery of identification data via the bus address, that is passive ge-tet formwork again. By the three last-mentioned measures (output of the IS signal message to the central controller and Passive circuit) is ensured that in the chain of Steue- only one module, each approximately module responds to the solicitation of identification data, that is, the ID in after the chain is carried out of the control modules of the series. After passing the identification signal IS the output terminal IS OFF the logic level "1" in the respective control module to logic level "0".

The above steps 16 to 22 are module-wise repeated until all control modules STML, STM2, submitted their identification data STM3. If this is the case (step 24), the self-configuration is completed (step 26) and the central controller is responsive the individual control modules STML, STM2, STM3 according to the predetermined control program among the respective configuration addresses.

As termination criterion for self-configuration, a waiting time can be provided. The central controller ZST waits a predetermined time after delivery of a request for identification via the bus address. Be issued on the communication bus BUS no identification data, so this is a sign that all devices connected to the communication bus BUS control modules STML, STM2, submitted their identification data STM3 have and that the whole chain of control modules is processed. In the example of fi gure 3, only the control modules are indicated. Of course, the method and the system may include any number of control modules of the invention.

The control program is in particular in the form of computer software would be realized. It can spread as a file via networks, stored on a data carrier like a floppy disk or CD-ROM, and especially in memory devices on the machine control or a computer, for example, on disk, NV-ROM (Non Volatile Read Only Memory) or (in a RAM chip Random Access Memory) to be stored. The control program may be included as a program element in a larger program. 4 shows a control system which includes the components of FIG. 2 In this system, however, an additional line IDENTACK is provided with the tralsteuerung a module to the Zen can provide feedback. Each control module has an additional output to IT-A, which is connected to the IDENTACK line. In the control system according to Figure 4, the self-configuration again proceeds according to the flowchart or control program according to figure 3. If the feedback to the central control, that the identification signal IS is given to the adjacent in the chain control module (step 22, first part) in this embodiment but not via the communication bus, but about the IDENTACK line. If a module is the last in the chain, this can be recognized by the fact that no acknowledgment signal to the IDNETACK line appears more after activating the SIGIDENTOUT line. A return message or the corresponding acknowledgment signal by the separate IDENTACK line with high transmission reliability.

Instead of the shared by all the control modules parallel IDENTACK line and individual, extending between the modules IDENTACK-lines can be provided in a further exemplary example. Each module then has in each case give a IDENTACK input and an output and can IDENTACK the adjacent module from which it has received the IS-signal feedback. The neighboring, already identified by the central controller in the chain module can then pass on to the central control this feedback via the bus line BUS. The IDENTACK line is then no parallel bus line more, but only a serial, cascade or chain-like connection between the control systems. The first control system STM 1 must not be more connected to the central controller. Is the first control system connected nevertheless with a IDENTACK line to the central controller, the feedback of the following modules can be cascaded via the JE weiligen IDENTACK lines back to the central control without using the bus line BUS.

Although the invention has been described with reference to a high-capacity printing system, it can also be applied in other fields, in which electronically controlled modules cooperate flexible or must be remodeled regularly, for example in production lines or communication devices.
