Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
A group of sub-layers and/or entities in the OSIRM that provides services to the layer above and requests services from the layer below.
Industry:Automation
An enclosed channel used to hold and protect wires, cables or busbars. A raceway may be made of either metal or insulating material. Raceways include conduit, tubing, and wireways.
Industry:Automation
The physical size of a motor, usually consisting of NEMA-designed D and F dimensions at a minimum. The D dimension is the distance in quarter inches from the center of the motor shaft to the bottom of the mounting feet. The F dimension relates to the distance between the centers of the mounting feet holes.
Industry:Automation
1) Adding, deleting, or changing the contents of records in a file. 2) Reorganizing the structure of a file to improve access to records or to change the storage space required.

Industry:Automation
To transfer information from one system or program to another. This typically involves conversion to ASCII format.
Industry:Automation
A group of two bits. In four-phase modulation, each possible dibit is encoded as one of four unique carrier phase shifts. The four possible states for a dibit are 00, 01, 10, 11.
Industry:Automation
An error detection scheme where all of the characters in a message are treated as a string of bits representing a binary number. This number is divided by a predetermined binary number (a polynomial) and the remainder is appended to the message as a CRC character. A similar operation occurs at the receiving end to prove transmission integrity.
Industry:Automation
The portion of a control circuit that carries the controlling signal for a device which, in turn, controls the primary current.
