Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
The sequential order of operations performed by a programmable controller when in the run mode.
Industry:Automation
A distributed control system drive product that is based on the Multibus platform and used primarily by the Rockwell Automation Drive Systems Group. It is a multi-tasking multi-processing multi-language system designed specifically for control of large coordinated drive systems, but may be used for other applications as well.
Industry:Automation
1) The effect of residual magnetism whereby the magnetization of a ferrous substance lags the magnetizing force because of molecular friction. 2) The property of magnetic material that causes the magnetic induction for a given magnetizing force to depend upon the previous conditions of magnetization. 3) A form of nonlinearity in which the response of a circuit to a particular set of input conditions depends not only on the instantaneous values of those conditions, but also on the immediate past of the input and output signals.
Industry:Automation
A security measure used to restrict access to a system, a specific function, or sensitive files. A password is typically a unique string of characters that a user types in as an identification code.
Industry:Automation
Part of the data link layer. See open-system interconnect reference model
Industry:Automation
1) A data terminal that has no internal processing capability ( processor) for manipulating data. 2) Contrasted with intelligent terminal
Industry:Automation
A method of ordering data records stored as a file, while also providing a way to access stored records.
Industry:Automation
An output circuit that provides a path to ground through a transistor (by connection to its collector) but does not provide a corresponding path to +V through a built-in pull-up resister or other means. Without an external pull-up, this collector circuit is open. Therefore, a pull-up resister must be provided by a load.
Industry:Automation
The shortest distance through air between conducting parts, or between a conducting part and the outer surface of the insulating enclosure considered as though metal foil were in contact with the accessible surfaces of the enclosure (as defined in NEMA Standard Pub. No. ICS 2, 1988).
