programmable logic controller

PLC. A processor-driven device that uses logic-based software to provide electrical control for machines and processes.

Rapid Roaming

A process that ensures fast handover of radio signals between access points and interruption-free roaming times. Rapid Roaming is a basic requirement for mobile operator control and monitoring in safety applications where enabling and emergency stop buttons are used.

Redundant

Refers to a device or system that duplicates or can take over the function of another device or system as a means to increase system reliability.

Risk Assessment

As it applies to the European Machinery Directive, a risk assessment is a required process intended to identify and evaluate all hazards associated with a machine.
