For computer networking, floor control allows users of networked multimedia applications to utilize and share resources such as remote devices, distributed data sets, telepointers, or continuous media such as video and audio without access conflicts.
It contains the base stations, which are called Node B's and Radio Network Controllers (RNCs) [1] which make up the Universal Mobile Telecommunications System (UMTS) radio access network. [2] This communications network, commonly referred to as 3G (for 3rd Generation Wireless Mobile Communication Technology), can carry many traffic types from ...
The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station. This protocol is specified by 3GPP in TS 25.331 [2] for UMTS, in TS 36.331 [3] for LTE and in TS 38.331 [4] for 5G New Radio. RRC messages are transported via the PDCP-Protocol.
Direct communication of plant floor equipment data is established by connecting to the PLC. Often, plant floor data is first collected and diagnosed for real-time control in a DCS or SCADA system. In this case, the MES systems connect to these Level 2 systems for exchanging plant floor data.
Plant floor communications refers to the control and data communications typically found in automation environments, on a manufacturing plant floor or process plant. The difference between manufacturing and process is typically the types of control involved, discrete control or continuous control (aka process control ).
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
A control panel is a flat, often vertical, area where control or monitoring instruments are displayed or it is an enclosed unit that is the part of a system [1] that users can access, such as the control panel of a security system (also called control unit).
The structure of an application with PAC. Presentation–abstraction–control (PAC) is a software architectural pattern.It is an interaction-oriented software architecture, and is somewhat similar to model–view–controller (MVC) in that it separates an interactive system into three types of components responsible for specific aspects of the application's functionality.
