Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
A set of procedures used for solving a problem in a finite number of steps.
Industry:Automation
Reversing the current in an armature coil as the coil moves from one pole to another. For a dc motor, this is done mechanically with brushes and a mechanical commutator that is an integral part of the armature assembly. For a brushless servo motor, commutation is done electronically with a feedback signal from a rotary position feedback element (such as an encoder) attached to the motor shaft.
Industry:Automation
1) A mnemonic used as an extension of a file name to identify the type or contents of a file. 2) The method of data representation used for a file.
Industry:Automation
A network designed to incorporate all devices — regardless of manufacturer or model — that can use the same communication facilities and protocol in compliance to some established standard(s).
Industry:Automation
Coaxial cable. A transmission line in which one conductor is centered inside and insolated from a metal tube that serves as the second conductor.
Industry:Automation
The time required for the controller to execute the instructions in the program. The program scan time may vary depending on the instructions and each instruction’s status during the scan.
Industry:Automation
1) To transfer a block (64 words maximum) of data to or from an I/O module in one scan. 2) Contrasted with single-transfer
Industry:Automation
A set of records stored in one order and linked in a different logical order by insertion of pointers in each record. In a list, the logical order or sequence of records is different from the physical order.
Industry:Automation
Root Mean Square. The effective value of an alternating current, corresponding to the dc value that produces the same heating effect. The rms value is computed as the square root of the average of the squares of the instantaneous amplitude for one complete cycle. For a sine wave, the rms value is 0.707 times the peak value.
Industry:Automation
1) A mode of operation for a point-to-point link with two physical circuits, in which messages or transmission blocks can be sent in both directions at the same time. 2) Contrasted with two-way alternate.
