3 Terms, Definitions and Abbreviations
3.1 Terms and Definitions
For the purpose of this code, the following terms and definitions apply.
3.1.1 Application software
The generic term of computer programs, processes, regulations and relevant documents
required to let DCS complete the supervision on a certain production process.
3.1.2 Availability
The ratio of the time for one device or system to correctly perform its designated function to
the total time to perform this intended function as planned, which is expressed in percent.
3.1.3 Baseband LAN
A kind of local area network that is able to encode the data and also is able to realize data
transmission without wave carrier modulation.
3.1.4 Bridge
A kind of functional unit interconnecting such two local area networks that use the same
logical link control protocol but may apply different medium access control protocols.
3.1.5 Broadband LAN
A kind of local area network that is able to encode and reuse the data and also is able to
realize data transmission by wave carrier modulation.
3.1.6 Bus network
A kind of local area network that has only one access between any two data stations and in
which the data sent by one station is usable for all other stations in the same transmission
medium.
3.1.7 Communication system
A kind of system that is composed of various communication links, protocols and functional
units and provides the effective communication among the component parts of computer
network. This system ensures the information transfer by a decided mode in a group of
interconnected stations.
3.1.8 Computer integrated process system-CIPS
The automatic control system integrating such functions as routine control, advanced control,
process optimization, production dispatching, enterprise management, operating decision.
3.1.9 Data circuit
A pair of relevant transmitting and receiving access that are provided for the two-way data
communication.
3.1.10 Data processing system
A kind of complex that is composed of device, method, program and person and is able to
complete a specific group of data processing functions.
3.1.11 Data station
A complete set of functional units that is also known as station and is composed of data
terminal equipment, data circuit-terminating equipment and its common interface.
3.1.12 Distributed control system-DCS
A kind of intelligent station network that is characterized by distributed control function,
centralized operating display and hierarchical structure. It is applied for the purpose of
controlling or controlling and managing an industrial process or factory.
3.1.13 Engineer's operating station
The intelligent station provided for the Engineer at the supervision level of distributed control
system to realize the system generation, which generally also has the functions of operator's
station.
3.1.14 Ethernet
A kind of networking technology of computer local area network, which specifies link of
physical layer, the electric signals and the contents of medium access layer protocol and
meets the technical requirements of IEEE 802.3.
The industrial Ethernet is compatible with the commercial Ethernet (IEEE 802.3) technically,
but it is better to satisfy the demand of industry site in such aspects as product material
selection, product strength, applicability and instantaneity, oper...
