Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
The process of detecting, locating, and correcting errors in hardware or software.
Industry:Automation
1) In a linear arrangement of parallel (bus) connections, a physical configuration such that each device is connected on the bus at the junction of two conductor segments, with no drop-line between the device and the junction of the conductor segments. 2) Contrasted with a star configuration and a trunk-line/drop-line configuration
Industry:Automation
A PROM that can be erased, usually with ultraviolet light, then re-programmed with electrical signals. As with all PROMs, it is non-volatile random-access memory. (See PROM, EEPROM, and UV-erasable PROM.)
Industry:Automation
Using armature voltage as the velocity feedback signal to an electronic speed regulator. This voltage is approximately directly proportional to motor velocity, assuming a constant motor field and ignoring IR drop. Armature-voltage feedback is used where the expense of a tachometer-generator for velocity feedback is not justified and a regulation accuracy of 2–5% is adequate.
Industry:Automation
A logical structure that keeps track of items waiting for processing whenever the system is unable to process each item immediately. It controls the order in which the waiting items are ultimately processed.
Industry:Automation
The process of one intelligent device accessing the memory of another, bypassing the other processor’s general registers.
Industry:Automation
Transaction field. A 16-bit field that indicates which message transaction is taking place.
