Introduction
RTU communication systems
Introduction
RTU communication systems are designed to meet the needs of the water/waste water industry, the oil and gas sector and other infrastructures, where remote monitoring and telecontrol are required to manage sites and substations spread over a wide geographical area.
1
RTU protocols and Telemetry systems provide communications suitable for the process values, maintenance and remote monitoring needs of infrastructures disseminated over a vast geographical area that may be difficult to access.
2
An RTU system consists of the following elements: bb A Telemetry Supervisor (SCADA) in a central control room bb A network infrastructure and a variety of suitable communication methods (LAN, WAN, modems, etc) bb A large number of RTU substations geographically distributed throughout the field

Main functions
Main RTU system functions include: bb Remote communications: vv Between remote RTU sites (coordination, synchronization) vv With the SCADA host system, controlling the central operator station (monitoring, detected alarm reports) and centralized databases (archiving of detected alarms or events) vv With the on-call staff (detected alarm indication) vv With the technical station (diagnostics, maintenance)
7
bb Data acquisition, processing and memorization: vv Process data sampling using standard or dedicated sensors, validation vv Exchange of data with other devices within the station, including controllers and operator consoles vv Use of digital or analog I/O, serial links, fieldbuses and LANs vv Event detection, time and date stamping, prioritization and logging as required by the application
8
bb Other functions: vv IEC 1131-3 programmable control: forcing, access control, load sharing, servo control vv Data logging vv Detected alarm and report notification by e-mail/SMS vv Web HMI: displaying the process, detected alarm handling, trend analysis, telecontrol

Cabling systems for Ethernet networks ConneXium™ hub and transceiver ConneXium™ hub
Introduction Hubs (concentrators) are used for transmitting signals between several media (ports). Hubs are “plug and play” devices that do not require configuration by the user.

ConneXium transceiver
Introduction ConneXium transceivers are used to: bb Create fiber optic linear bus topologies, for devices with a twisted pair cable Ethernet connection bb Interface devices with a twisted pair cable Ethernet connection with a fiber optic cable
6
Transceivers are “plug and play” devices that do not require configuration by the user. ConneXium transceivers provide fiber optic connections for transmission in areas subject to interference (high levels of electromagnetic interference) and for long distance communications.
