    1.1 The master unit: Sx2WEB24 (SH2WEB24 or SB2WEB24) The system is based on a central CPU, the Sx2WEB24, a Linux based embedded PC that manages all the smart functions. It is programmed by means of powerful software, the Sx tool. The Sx2WEB24 has the Ethernet communication capability to be remotely controlled and monitored by smart-devices/PCs;...

  • Page 8: Bus Generators

    1.2 Bus generators The Sx2WEB24 (i.e. SH2WEB24 or SB2WEB24) is the brain of the smart-house system but it cannot work alone and it needs the Dupline® bus generators to send commands to the slave modules and collect information from them. For this reason, the Dupline® bus generators can be considered as the pulsating heart that makes all the information flow.

    Example 3: The bus generators SH2MCG24 do not need to be put all together in a DIN rail, and they can be mixed with the Dupline® modules as is shown in the picture below. Sx2WEB24 SH2MCG24 SH2RE16A4 SH2RE16A4 SH2MCG24 SH2INDI424 SH2INDI424 SH2MCG24 HSBUS Also in this case there is no need to wire the RS485 for the HS speed bus since the local bus connector...

  • Page 11: The Dupline® Bus

    1.2.2 The Dupline® bus The Dupline® bus is a signal transmission system that reduces the need for wires, as compared to an ordinary installation. Using only 2 wires, the information can be transmitted from up to 2 km away. Many input and output modules are supplied from the same 2 wires.
  • Page 12 The so-called decentralised modules can be divided into the following groups: Light switches PIR sensors Temperature displays Water and smoke detectors Wind sensors Humidity sensors Light sensors Decentralised input/output modules The installation is not to be engineered around the Dupline® bus because it can be matched to the application.

    1.2.3 Cable and installation tips 1.2.3.1 New Installation Planning When planning a new installation, a generic Bus cable can be used: it is better to use a twisted cable in order to prevent electrical noise from affecting one conductor more than the other and thereby creating an unbalanced Dupline®...
  • Page 14 1.2.3.2 Installation on Existing Cables If the installation uses existing cables, it is important to verify the cross section of conductors according to the above cable section table. Once the cable size is checked, it is important to ensure that there is no leakage between the two conductors and, also, no leakage from the conductors to ground or shield.

At the same time, it could be necessary to place some modules at the end of the Dupline®...
  • Page 18 1.2.4.2 Repeater wiring The repeater regenerates the voltage level of the Dupline® signal from the bus generator and also provides an output drive capability of up to 300mA. Since most of the Dupline slave modules are bus- powered, the SB2REP230 provides the bus power supply to the modules connected to it. Example 1 Sx2WEB24 SH2MCG24...
  • Page 19 The Dupline® repeater does not create any new Dupline® network: all the Dupline® slave modules connected to the SB2REP230 are part of the same network generated by the SH2MCG24 which the repeater is connected to. Example 2 The example below shows the network topology Network Network Module...
  • Page 20 1.2.4.3 Isolator feature In addition, the isolator feature contributes to the separation of the sides of the bus for maximum safety. The primary and secondary Dupline® signals are isolated, which means the primary side, made up of the modules connected to the Dupline® generator, will continue to operate in the case of a short circuit on the secondary side, made up of the modules connected to the Dupline®...
  • Page 21 Example of correct wiring: The example below shows a correct network design, where the installer has placed the Dupline® DIN- rail modules in different cabinets and the distances have been calculated by considering the cable section and the voltage drop due to the bus-powered connected modules.

Smart Dupline® implements a master-slave protocol running over standard Dupline® networks. The concept of SmartDupline® is based on the SIN: it is a Specific Identification Number that is unique for each Dupline®...

    Recommendations: Do not connect one SH1DUPFT to two Dupline® networks, otherwise the two buses will be short-circuited: the situation below must be avoided. This connection must be avoided otherwise two Dupline® networks will be short circuited. If this should happen, the system will not be damaged since the bus is protected, but it will not work properly.

    1.9 Sizing of Carlo Gavazzi DC power supply The smart-house system is powered by 24 Vdc nominal (15-30 Vdc) Since most of the Decentral Dupline® slave modules are powered by the bus, the sizing of the power supply has to be based on the DIN-rail modules, and among these only the ones powered by 15 to 30 Vdc: the power dimmers and the relay output modules that switch 230 Ac load are powered by 230Vac.
