or the capability to change functionality or sizing of software functions by
changing parameters without having to modify or regenerate software.
configuration
Physical installation of hardware modules to satisfy system requirements; or the
selection of software options to satisfy system requirements.
connector
Coupling device used to connect the wire medium to a fieldbus device or to
another segment of wire.
ControlNet network
An open control network that uses the producer/consumer model to combine
the functionality of an I/O network and peer-to-peer network, while providing
high-speed performance for both functions.
cycle
Scanning of inputs, execution of algorithms and transmission of output values to
devices.
device
The term in this manual refers to the instruments that make up the
fieldbus system.
