Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
1) An I/O module for which each input or output that has an individual connection that corresponds directly to a data table bit or word that stores the value of the signal at that I/O circuit (digital or analog). This allows the ladder logic to have direct access to the I/O values. 2) Contrasted with intelligent I/O module
Industry:Automation
1) On a ladder logic rung, the state of a logic element of a conditioning instruction when the condition for which it is examining is not detected. 2) Contrasted with true
Industry:Automation
A regenerative drive contains the inherent capability and/or power semiconductors to control the flow of power to and from the motor.
Industry:Automation
Logic that produces outputs controlled by the previous state of the logic array, by the presence of a discrete timing interval, and by the input states and delays. Compare combinational logic
Industry:Automation
(INT) Pertaining to a motor that never reaches equilibrium temperature (equilibrium) because it is permitted to cool down between operations. For example, a crane, hoist, or machine tool motor is often rated for 15% or 30% duty cycle.
Industry:Automation
A measure of a body’s resistance to changes in velocity, whether the body is at rest or moving at a constant velocity. The velocity can be either linear or rotational. The moment of inertia (WK2) is the product of the weight (W) of an object and the square of the radius of gyration (K2). The radius of gyration is a measure of how the mass of the object is distributed about the axis of rotation. WK2 is usually expressed in units of lb-ft2.
Industry:Automation
An intelligent I/O module or program instruction providing automatic closed-loop operation of process control loops. For each loop, this module or instruction can perform proportional control and optionally integral control, derivative control, or both.
Industry:Automation
The range of values of the controlled variable (such as temperature or shaft rotation) that corresponds to full operating range of the final control element (such as a valve or servo motor).
Industry:Automation
1) An I/O module that provides some on-board processing of input values to control some output values without going through the data table for control by the ladder logic. An intelligent I/O module may have digital I/O circuits, analog I/O circuits, or both. 2) Contrasted with direct I/O module
Industry:Automation
1) Pertaining to a method of signal transmission through two wires. The transmission always has opposite states. The signal data is the polarity difference between the wires; when one is high, the other is low. Neither wire is grounded. The circuit may be either a balanced circuit, a floating circuit, or a circuit with a high-impedance path to ground from either end. Usually used in reference to encoders, analog I/O circuits, and communication circuits. 2) Contrasted with single-ended
