Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
A programming technique of triggering some step by means of an on-to-off transition of an input signal. The on-to-off transition is considered the trailing edge of the input pulse.
Industry:Automation
A check of the sum of the parity bit plus all of the data bits in each word to determine whether the sum is even or odd. A failure of the parity check indicates that a data bit has been corrupted.
Industry:Automation
In the Advisor system, the mode in which ASCII and graphic characters are presented to yield a resolution of 80 by 48 lines or columns.
Industry:Automation
A standard bar code type for retail packaging in the United States. See EAN
Industry:Automation
Using a diode in a circuit to protect against damage in case polarity of the power supply should be accidentally reversed.
Industry:Automation
The ability to do addition, subtraction, multiplication, division, or advanced math functions within a processor.
Industry:Automation
A load connected to the end of a transmission line. To avoid signal reflections, it must match the characteristic impedance of the line.
Industry:Automation
A circuit design feature of a dc motor shunt field supply that reduces the supply voltage output after a predetermined period of time. On many field supplies, this means a 50% reduction in output voltage 2 to 3 minutes after machine shutdown (idle). A field economy circuit serves to reduce standby power consumption and prolong the insulation life of the motor field windings.
Industry:Automation
An immediate response transmission from a station after receiving a transmission, without requiring the station to acquire the token. Reception of a positive acknowledgment indicates successful reception of the original transmission; absence of a positive acknowledgment, or reception of a negative acknowledgment, indicates failure of the original transmission and a need for some recovery procedure.
Industry:Automation
A standard high-speed parallel interface defined by the X3T9.2 committee of the American National Standards Institute (ANSI). An SCSI interface is used for connecting computers to peripheral devices, such as hard-disk drives and printers, and to other computers and local area networks requiring high-speed data transfer.
