Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
1) A portion of a protocol data unit that contains protocol control information and precedes the start of data, if present. 2) In data storage, a file header identifies the file by name, size, and time and date of creation or revision.
Industry:Automation
A numbering system used to express individual decimal digits (0 thru 9) in 4-bit binary notation.
Industry:Automation
Devices that allow only selected pairs of mating connectors to be plugged into each other.
Industry:Automation
The type of architecture used in an A/D converter that combines oversampling, noise-shaping, digital filtering, and decimation. The analogue input signal is continuously sampled at a rate determined by a master clock and a selected gain. A charge-balancing A/D converter (sigma-delta modulator) converts the sampled signal into a digital pulse train with a duty cycle that represents the digital value.
Industry:Automation
1)To read from memory based on a logical address. 2) See physical read
Industry:Automation
A signal that has a zero value before a certain instant of time and a constant nonzero value immediately after that instant.
Industry:Automation
Special programme instructions that control and delimit specific programme areas such as fault zones.
Industry:Automation
1) A position expressed in reference to the current position. Usually expressed in reference to a move that is an increment from the current position. 2) Contrasted with absolute position
Industry:Automation
A numerical control system where a computer is used to perform some or all of the basic numerical control functions.
Industry:Automation
The type of memory in which each storage location is by X/Y coordinates, as in core or semiconductor memory. (Tape or bubble memory cannot be random access.) Thus, the data access time is independent of the location of the data. Unless stated otherwise, RAM usually implies read/write and volatile.
