Company Profile:
Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
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.
Industry:Automation
1) An ac adjustable-frequency drive. 2) A particular section of an ac drive. This section uses the dc voltage from a previous circuit stage (intermediate dc circuit) to produce a pulse-width-modulated or stepped ac current or voltage waveform that has characteristics similar to the desired sine-wave frequency. 3) A circuit whose output signal is the inverse of its input (a positive-going pulse is inverted to a negative-going pulse, and vise versa).
Industry:Automation
A product that can be located in a hazardous location.
Industry:Automation
In an SLC controller, the process of transferring contents of the memory module to the processor memory at power up.
Industry:Automation
Transfers that occur repeatedly at a regular specified interval, asynchronous to the program scan.
Industry:Automation
A grouping or a number of bits in a sequence that is treated as a unit.
Industry:Automation
An error-checking method that adds a check or parity bit to each character in a message so the number of 1 bits, including the parity bit, in each character is odd (odd parity) or even (even parity).
Industry:Automation
The portion of memory or auxiliary storage that contains the data needed by a program.
Industry:Automation
1) An operational state in which a communication module is sending and/or receiving at maximum capacity. When the module receives more messages than it can process, it inhibits message entry. 2) More generally, the condition of a device or system in which a further increase in input no longer results in an appreciable change in output.
