1) A screw, solder, or other electrical connection point. (See I/O terminal) 2) A peripheral device that provides access to a system.
Industry:Automation
A bit in a data table word that does not correspond directly with a physical I/O circuit.
Industry:Automation
A small oscillation signal superimposed on a velocity signal to overcome the effect of static friction that would otherwise occur at zero velocity. Without a dither, a low-velocity signal may be unable to overcome the static friction.
Industry:Automation
A programmable controller system configuration consisting of a primary and a backup (secondary) processor. If the primary processor fails, the backup processor takes over operations automatically.
Industry:Automation
A set of conventions governing the format and timing of data between communication devices.
Industry:Automation
A bit that is set to indicate that the result of an operation is less than the minimum value that can be contained in a register.
Industry:Automation
In programming, a signal that is used to govern access to shared system resources. A semaphore is a flag variable — an indicator — that helps maintain order among processes that are competing for use of such critical resources as microprocessor time and communication ports. See also flag
Industry:Automation
A file of data containing the history or current status of a factor or entity of interest to an organization. A master file must be updated periodically to maintain its usefulness.
Industry:Automation
A software program that operates on, or uses as data, other programs to translate higher level instructions into machine-executable instructions.
