Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
An error-checking method that adds a cheque 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.
Industry:Automation
A programme or part of a program; a coherent sequence of steps undertaken by a programme (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
