Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
The process of controlling and monitoring data table bits, bytes, or words by means of the user program to vary application functions.
Industry:Automation
1) Having to do with the actual time during which physical events take place. 2) The performance of a computation during the actual time that the related physical process transpires so that the results of the computations are useful in guiding the physical process.
Industry:Automation
A circuit on an I/O module that converts ac signals from a machine/process switching device to backplane logic level dc signals. By definition, it is always a digital circuit (on/off). By implication, it usually has a direct relationship with the data table (i.e., a data table bit directly reflects its state).
Industry:Automation
A programming technique that allows reports to be printed sequentially, in an orderly fashion, regardless of how quickly they are requested through the user program.
Industry:Automation
A standard means of communication between open systems proposed by the ISO. It is a 7-layer model that represents network architecture. The 7 layers and the services they provide are as follows:
Industry:Automation
Information about a specific entity (an I/O chassis, an I/O module, an I/O). For example, an I/O definition file may contain a tag (definition) for each I/O. Each tag may consist of several items, each defining some aspect of the entity. At a minimum, a tag must include a tag name (a symbolic name) to establish that symbolic address to represent the physical or logical address of the data.
Industry:Automation
The amount that a controlled variable exceeds the desired value after a change of input.
Industry:Automation
Using a direct communication link to transmit part programs from a computer to a numerical control system.
