摘要:
A controller for using a first data item transmitted via a network to generate a second data item for controlling an entity to be controlled over the network, wherein the controller is characterized in being provided with: an adjustment unit for adjusting, with respect to the maximum delay time permissible on the network, the time by which generation of the second data item is started using the first data item after the first data item has been received; and a delay compensation unit, designed using a model of the entity to be controlled and the maximum delay time permissible on the network, for compensating for the delay of the first and second data items that can be generated using the network.

A machine for producing disposable products anticipates when a current run of a product size is coming to an end, and therefore begins loading of material rolls intended for the next product size or code that will be run. An integrated production facility layout automatically orders and stocks raw material based on production plans, and commands a production machine to produce specific products of differing configurations, and automatically loads appropriately sized raw materials into the process.

The invention relates to a process for manufacturing parts that is based on the simultaneous analysis of a plurality of different statistical indicators representative of a characteristic size of the parts, in which: an overall validation set corresponding to a set-theoretic combination of the various validation sets of each statistical indicator is defined; an overall sanction set corresponding to a set-theoretic combination of the various sanction sets of each statistical indicator is defined; and an overall control set comprising the pairs (μ;σ) not contained in the overall validation set and in the overall sanction set is defined; and it is determined to which overall set, from the overall validation set, the overall sanction set and the overall control set, the pair comprising the mean μ m and the standard deviation σ m of the measured characteristic size belongs, and the manufacture is controlled depending on the overall set thus determined.

There is described herein a real-time scheme, implementable in software, hardware, or a combination thereof, to detect a resonating frequency of a structure from a sensed signal and dynamically set the center frequency of an adaptive compensator (306) for effective attenuation of the resonating frequency.

An industrial data indexing system facilitates discovery and indexing of plant-wide data residing on multiple different data platforms. The indexing system automatically inventories industrial devices and other data sources located throughout a plant, and identifies available data items on each data source. The indexing system indexes the discovered data items in a federated data model that can subsequently be searched to locate data items or tags of interest. The federated data model records references to data items found on different types of data sources, including but not limited to industrial controller programs, human-machine interface applications, data historians, device documentation stores, inventory tracking systems, and other such data sources. The indexing system also discovers and records interdependencies between data items, which can be used to improve relevancy of search results returned to the user.
摘要:
In a process variable transmitter, a sensor signal is sampled, using a clock signal, at a sensor sampling frequency. An interference signal from the device housing is also sampled at the same sensor sampling frequency. A comparison is made to determine whether the level of the interference signal at this frequency or harmonics of it exceed a threshold level. If so, the clock signal is changed to adjust the sensor sampling frequency away from the previous frequency where the level of noise is too high.
