摘要:
The invention relates to a synchronous, clocked communication system, for example a distributed automation system, whose users can be any automation components and that are interconnected via a data network (1). The method for integrating local input/output components (2, 3) allows integration of the local input/output components (2, 3) into the synchronous, clocked communication system in such a manner that they can use its properties without reservation, thereby allowing the detection of input signals and the output of output signals in a deterministic and synchronous manner in the local input/output components (2, 3). The inventive method further allows for the detection of input signals with an exactness smaller than the length of a communication cycle of the communication system and for the support of switching the output signals in smaller time segments than the length of a communication cycle, which is especially useful for control cams. The invention further allows for the synchronization of the detection of actual values and the output of desired values of various automation components such as, for example, input/output components (2, 3) and digital drives (4, 5,6). Any bus system such as, for example, field bus, profibus, Ethernet, Industrial Ethernet, FireWire or for example PC-internal bus systems (PCI) etc. can be used as the data network (1) of the communication system.

The invention relates to a synchronous, clocked communication system, for example a distributed automation system, whose user can be any automation components and are interconnected via a data network (1) for the purpose of mutual data exchange. Any bus system such as, for example, field bus, profibus, Ethernet, etc. can be used as the data network (1) of the communication system. One user of said communication system is configured as a clock and ensures distribution and observation of the used communication clock pulse to all users and by all users. By means of the same mechanism, the clock can introduce a relative time clock (9) in the entire communication system for all users. The respective user is then also master of the relative time clock (9) and the valid relative time (16). All users of the communication system are thus permanently synchronized to the relative time clock (9) with the valid relative time (16) which is valid for the whole system and therefore have the same concept of time at any time. The inventive system and method improves and/or even facilitates the putting into operation of applicative sequences, synchronization of simultaneously occurring events, time-wise accuracy in the detection of events or switching of outputs.

The synchronization of a bus master with a bus slave allows for the desired hierarchization of buses. To this end, a bus slave (2) on a bus (3) receives the synchronization information (S) of an associated bus master. This clock information is filtered by means of a PLL (6) and missing clock signals are reconstructed. The clock signal (Z*) that is now clean is fed to one or more parallel bus masters (1', 1'') of other buses (3', 3'') which generate the corresponding clock information (S', S'') by means of the required frames on the corresponding buses. The inventive principle functions independent of the particular bus system so that it is possible to operate a plurality of identical buses or different bus systems in a hierarchically synchronous manner.

Modular production machines consisting of appliances and components are controlled by means of projects. A project is the establishment of an arrangement of appliances and modules. The invention relates to a novel project according to which a plurality of machine objects is associated with the determined arrangement locations. In this way, the projects have a variability in terms of different machine objects, which is enabled by an engineering system. A control system (a run-time system) can affect a corresponding selection from the options. The invention enables the economical control of production machines in which some appliances or components can be selectively replaced by other appliances or modules.

The invention relates to method and to a system for transmitting data, comprising a first data network (1) with first means for transmitting data in at least one first transmission cycle. The first transmission cycle is divided up in a first section (4) for transmitting real-time critical data and a second section (5) for transmitting non real-time critical data. The system further comprises a second data network (2) with second means for transmitting data in at least one second transmission cycle. The second transmission cycle is divided up in a third section (7) for transmitting real-time critical data and in a fourth section (8) for transmitting non real-time critical data. A coupling unit (13) is used to transmit real-time critical data from the first section to the third section.
