Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
A program or part of a program; a coherent sequence of steps undertaken by a program (e.g., a data transfer operation).
Industry:Automation
In any control loop, the difference between the set-point signal and the feedback signal. An error is necessary before a correction can be made in the controlled system. In a positioning loop, the difference between the instantaneous position command signal generated by the summation of the feedrate, and the actual position signal generated by the summation of the feedback (e.i., following error).
Industry:Automation
Two output modules having the same address. Each output on the one module is controlled by the same output image table bit as the corresponding (parallel) output on the other module.
Industry:Automation
A hardware assembly that houses devices such as I/O modules, adapter modules, processor modules, and power supplies.
Industry:Automation
An error-checking technique based on an accumulated exclusive-OR of transmitted characters. An LRC character is accumulated at both the sending and receiving stations (similar to CRC).
Industry:Automation
The portion of memory reserved for saving programs, routines, and subroutines.
Industry:Automation
1) An output that, when turned on, supplies a negative dc current to its load. 2) Contrasted with source output
Industry:Automation
A program or routine, such as an editor or debugger, designed to perform a particular function of general usefulness. Compare to application program and operating system
Industry:Automation
In binary synchronous communications, this DLE sequence is sent by a receiving station to indicate that it is temporarily not ready to receive.
Industry:Automation
Undesirable fluctuations in motor speed that can occur after a step change in speed reference (either acceleration or deceleration) or load.
