    摘要: A method is based on a communication- and data network for the automatic time synchronization of field devices, namely fill-level measuring devices and pressure measuring devices as well as field-device control units. The method comprises the steps of: determining a current time value by the field device or by the field-device control unit, and providing a desired value in a central server. Furthermore, the method comprises the following steps: comparing the current time value with the desired value, and setting the current time value to the desired value when the desired value differs from the current time value by more than a predetermined threshold value.

    摘要: A synchronization method, a control system and a slave unit for the time synchronization of at least two slave units, in which the slave units and the master unit are connected by two signal lines. A signal transmitted by the master unit returns to the master unit after passing through all the slave units. Two independent counters are provided in each slave unit, these counters being activated by reception of a reference signal transmitted by the master unit. The first time counter counts the time since the receipt of the reference signal via the first signal line and the second time counter counts the time since the receipt of the reference signal via the second signal line. The counter contents are read out as soon as the sum of the counter contents reaches a signal throughput time transmitted previously by the master unit.

    摘要: The invention relates to a synchronous clocked communication system, for example a distributed automation system, the stations of which can be arbitrary automation components and which are coupled to one another via a data network (1). Using the disclosed method for integrating decentralized input/output modules (2, 3), these decentralized input/output modules (2, 3) can be linked into the synchronous clocked communication system in such a manner that they can use their characteristics unrestrictedly. Thus, in particular, the detection of input signals and the output of output signals is possible in a deterministic and synchronous manner in the decentralized input/output modules 2, 3. In addition, the disclosed method enables input signals to be detected with an accuracy of less than the length of one communication cycle of the communication system and to support the switching of output signals in smaller time granularities than the length of one communication cycle which, in particular, finds use, e.g. for switching cams. In addition, the invention provides for synchronization for actual-value detections and nominal-value outputs of the most varied types of automation components such as, e.g. decentralized input/output modules (2, 3) and digital drives (4, 5, 6). All possible bus systems such as, e.g. field bus, professional field bus, Ethernet, industrial Ethernet, FireWire or also bus systems internal to a PC (PCI) etc. are conceivable as the data network (1) of the communication system.
