Description / Abstract:
This International Standard defines a protocol for the physical
layer (PHY) and the data link layer in order to construct a
reliable and high-speed data transmission network between devices
on industrial sites such as factories and plants. This network
specification provides a standardized protocol to provide a
framework for various industrial devices to establish a simple,
low-cost, energy-efficient, and high-speed network between them. In
order to fulfil the service requirements of the factories and large
plants, this network specification is designed to enable devices to
establish a network by themselves without help of any
infrastructure and reliably exchange various kinds of data,
including real-time audio and video data, between them. In addition
to high transmission rates, Quality of Service (QoS) for multimedia
data - such as video - is also provided.
The devices mentioned in this International Standard refer to
equipment that is and can be used in industrial sites such as
factories and automated assembly lines. Such devices include PLC
(Programmable Logic Controller), and CNC (Computerized Numerical
Controller) and manufacturing robots. However, beyond such
conventional devices, devices mentioned in this International
Standard include personal IT devices that workers may carry and use
while working, including cellular phones, personal industrial
digital assistants (PDA), and laptop PCs.
