A continuously executed background program used to check for, and to report, alarm conditions in the controllers it monitors.
Industry:Automation
The digit that represents the smallest value within a string of digits.
Industry:Automation
An open control network that uses the producer/consumer model to combine the functionality of an I/O network and a peer-to-peer network, while providing high-speed performance for both functions.
Industry:Automation
A control system involving one or more feedback control loops, which combine functions of controlled signals and commands, to keep stable the relationships between the two. Contrasted with open-loop system
Industry:Automation
A totally enclosed machine is one so enclosed as to prevent the free exchange of air between the inside and the outside of the case but not sufficiently enclosed to be termed airtight (NEMA standard).
Industry:Automation
The distance an axis travels each revolution of its lead screw. If the lead screw has only one thread, the lead is equal to the pitch. See pitch
Industry:Automation
An organization established to promote development of international standards.
Industry:Automation
A control unit that includes a means of disconnecting an externally operable circuit, motor branch-circuit overcurrent protection, and a magnetic motor controller with associated auxiliary devices (when used). The disconnecting means and motor branch-circuit overcurrent protection consist of a fusible disconnecting device or circuit breaker. If the latter is used, it is either an inverse-time (thermal-magnetic or dual magnetic) or an instantaneous magnetic type circuit breaker. The motor controller includes motor overload protection unless equivalent protection is otherwise provided. Two sets of externally operable circuit disconnection means, each with branch-circuit overcurrent protection and a magnetic motor controller, can be mounted in a single compartment to form a dual unit (as defined in NEMA Standard Pub. No. ICS 2, 1988).
Industry:Automation
A transducer that generates an electrical signal in response to a detected change in light intensity.
