Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
A quantity that denotes both magnitude and direction. Vectors are commonly represented by a line segment with an arrow; the length represents the magnitude; the orientation in space and the placement of the arrow at one end of the line represents the direction.
Industry:Automation
Light Amplification by Stimulated Emission of Radiation. A device that converts input power into a very narrow beam of coherent light (light that is all a single frequency and in phase).
Industry:Automation
When a permanent-magnet dc motor is subjected to high current pulses, the magnets may become slightly demagnetized, resulting in a lower torque constant.
Industry:Automation
A marker of some type used in processing or interpreting information; a signal indicating the existence or status of a particular condition. Flags are used in such areas as communication, programming, and information processing. A flag can be a code, embedded in data, that identifies some condition, such as the beginning or end of a word or a message; or it can be one or more bits set internally by hardware or software to indicate an event of some type, such as an error or the result of a comparison of values.
Industry:Automation
An instruction that causes the processor to deviate from executing instructions in order, by jumping to another place in the program.
Industry:Automation
The quantity of characters for use in each of the digital positions of a numbering system; the octal radix is 8; the decimal radix is 10; the hexadecimal radix is 16.
Industry:Automation
1) A form of communication in which one station has master status, which allows it to initiate communication with any other station on the link; while each of the other stations has slave status such that it can only send replies to commands from the master, and send command messages to the master in response to being polled by the master. 2) Contrasted with peer-to-peer communication
Industry:Automation
1) In software terms, a register or group of registers used for temporary storage of data, to compensate for transmission rate differences between the transmitter and receiving device. 2) In hardware terms, an isolating circuit used to avoid the reaction of one circuit with another.
Industry:Automation
A range of motor operation where motor speed is controlled by field weakening. In this range, motor torque decreases as speed increases. Since horsepower is speed times torque (divided by a constant), the value of horsepower developed by the motor in this range is constant.
Industry:Automation
Logic in which the state of each output is controlled only by the states of inputs and the switching-transition delays encountered in the logic path. Compare sequential logic
