Mobile communications for industrial applications - CERN

GlossaryAbbreviations, termsPCMCIARLMRoamingSNMPThin ClientTIATouch-ScreenUSBUMTSWANWinCCWireless WANExplanationsStandard for PC plug-in cards (credit card size). PCMCIA cards (Personal ComputerMemory Card International Association) are primarily used for input/output(e.g. modem) and memory expansions.Radio Link Module; wireless LAN access point of SIMATIC NET.Property of wireless LAN systems which permits free movement of wireless LANstations even beyond the limits of the radio cell of an access point. The station cantransfer from one radio cell to the next without a noticeable interruption if bettertransmission properties exist with the latter.Simple Network Management Protocol; standardized protocol for transport ofnetwork management information.Client computer operating in a server network. The thin client has direct access to thedata and applications of all servers of the network. The applications are executed onthe server, and are only "visualized" on the thin client.Totally Integrated Automation; Siemens system for uniform configuring/programming,data management and communications.The touch-sensitive screen of the MOBIC which recognizes the touched position onthe surface (usually made using a pen) and which converts it into the desired action(e.g. movement of cursor).Standard for connection of I/O devices. USB (Universal Serial Bus) supports relativelyhigh data transmission rates, and can be used to connect several devices to onesingle computer.Universal Mobile Telecommunications System, standard for mobile voice, audio,picture, video and data communications at a transmission rate up to 2 Mbit/s.Wide Area Network; data network with a diameter of more than 50 km.Open process visualization system for operation and monitoring of SIMATIC HMI.Communication between stations carried out by the transmission of electromagneticwaves through the air.15
