Each sensor and ac-tuator needs its own wiring, which makes the initialinstallation cost high.

2 Expansion is also a problem, , serial bus technology has become an in-creasingly important part of the conceptsof electrical installations for buildings, industrialprocesses and public services. There are numerousadvantagesinusingabussystem,whic hreplacesabundle of parallel wires with a single 2-wire and fast installation reduces labor costsignificantly,andthepossibilityofexp andingthesy-stem using the existing cabling makes it easyto adapt to changing needs. Bus systems alsoWhat is Dupline ?Dupline is a field and installationbus that offersunique solutions for a wide range of applications inbuilding Automation , water distribution, energy ma-nagement, railway systems and many other analog signals over several km, via an ordinary2-wire cable.

3 And its modular design and simpleoperating principle enable even novices to imple-ment its use in new or existing applications. Soluti-ons are engineered by combiningproductsfromthewide range of Dupline modules, including digitaland analog I/O modules, PLC and PCinterfaces, to exchange data between modules and bet-ween a central controller and cost-effective access to a larger number ofsignals. This supports the increasing demand forautomation systems to collect and use more andmore data to optimize cost and is typically used as a remote I/O system,creating a link between field devices, such assensors, contactors, valves, pushbuttons etc. anda central Monitoring Controller, which may be aPLC, PC or the Dupline Controller. But Dupline can also be used as a simple wire replacement sy-stem where signals are transmitted peer-to-peerwithout involving a controller or other intelligentunit.

4 The Dupline signals can be transmitted notonly on copper wire, but also on fiber optic cable,via radio modem, on leased telephone lines or viaGSM Modem. Dupline has proven its since1986. And even though the latest ASIC technologyis used today, the new Dupline modules are stillcompatible with those installed 20 years :Dupline used as wire replacement system(peer-to-peer)INOUTINOUTT raditionalDuplineInstallationInstallatio nOUTINOUTINWhy use Dupline ?Many criteria have to be considered when selectinga fieldbus system. These include transmission di-stance capabilities, easy operation, noise immunity, ,ofcourse, ,itisimportantto define the key application requirements in order tooptimize the bus system for the specific task. ThestrengthoftheDupline systemliesinauniquesetoffeatures that enable elegant, flexible and cost-ef-fective solutions for a wide range of of these features originate from the effectivetime-division multiplex technology used.

5 Theefficiency of the protocol allows a low carrierfrequency of 1 kHz, providing long transmission di-stance and superior noise immunity. Hence, Du-pline is capable of transmitting multiple digital andanalog signals over distances up to 10 Km, via anon-shielded, non-twisted 2-wire cable, withoutusing repeaters. These unique Dupline featuresprovide considerable cost savings in many installa-tions, especially when existing ordinary cables areavailable for use. Another important Dupline characteristic is easy handling in all project does not take an engineering degree to work withDupline .NoPCisrequired,sincethecodingofad-dress es and testing is carried out by means of sim-ple handheld devices.

Du-pline is system independent and open for interfa-cing with basically any kind of controller.

It isa system of high precision, be-cause each parking bay has anultrasonic sensor that detectsand indicates occupancy. Thesensors and displays are linkedtogether via a Dupline 3-wirebus for power and communica-tion, thereby enabling each dis-play to read the status of thesensors within the area it hasbeen configured to desired, a PC can be con-nected to the system.
