Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
A hardware interrupt that triggers a single scan execution of a PII program whenever an interrupt signal is detected at an input circuit of a PLC processor module.
Industry:Automation
An expression for maximum encoder speed in Hz. May also refer to the maximum rate at which the control loop can accept encoder signals. The actual bandwidth of the encoder and the capability of the controller to process encoder signals may not be the same.
Industry:Automation
The power loss in an iron-core transformer or other ac device because of magnetic hysteresis.
Industry:Automation
1) An output that, when turned on, supplies a positive dc current to its load. 2) Contrasted with sink output
Industry:Automation
A program running under DOS that remains loaded in memory even when it is not running so that it can be quickly be invoked for a specific task performed while any other application program is operating.
Industry:Automation
In communication protocol, the procedure executed by the network to send a message designated at the application layer. This includes: station processing time, media access, transmission, and turn-around times for both stations until the reply is available at that application layer.
Industry:Automation
Unit space not equipped to accept a future unit (as defined in NEMA Standard Pub. No. ICS 2, 1988).
Industry:Automation
A hardware or software system that produces motion (i.e., index) profiles. Usually the index profile is trapezoidal, but can be rectangular, triangular, parabolic, or sinusoidal.
Industry:Automation
An extended application layer protocol used by Allen-Bradley intelligent sensing devices to communicate with other devices and host processors. IDP commands and responses are inserted as data within the PCCC layer.
