Page 20Network Design 51350-18 Aquatrend Interface Network.fmSection 22.2.8 Digital Display Module (DDM)The Digital Display Module (DDM) is an eight-character display that can beattached to sensors to provide a local digital reading. Once the display isadded to the network and assigned to the sensor by the Master AquaTrendInterface, it will automatically display data from the sensor. For sensors thathave multiple parameters (measurements), you can choose which parameteryou want to display on the DDM. See theDigital Display Module Manual fordetailed information.2.2.9 Repeater ModuleThe AquaTrend Repeater module is a physical layer repeater used to extendthe length of the AquaTrend Network by a maximum of 500 meters. A total ofthree such devices can be installed on the AquaTrend Network to extend thetotal length of the network to 2000 meters.2.3 Network Design Based on Wiring Topologies on page 83, determine the appropriateconfiguration for your operation by considering the following criteria;descriptions of each device is given in section 2.2.Note: All AquaTrend Interfaces on asystem display measurements andmenus, but only the MasterAquaTrend Interface can performnetwork operations through theNetwork Menu.The system can contain as many as nine AquaTrend Interfaces but onlyone can be the Master AquaTrend Interface. Each AquaTrend Interfaceis programmed in an undetermined state when shipped from the factoryand must be designated as a Master or Remote when initially attached tothe network.If more than one AquaTrend Interface is to be attached to the network,the Master AquaTrend Interface will be designated before otherAquaTrend Interfaces are added. Additional AquaTrend Interfaces will bedesignated as Remotes.Select the number of PS1201s based on the wattage needed and thedistance between the power supplies and the devices. Each PS1201Power Supply provides 25 watts. Available devices and their wattages arelisted below and in the PS1201 manual.If a system larger than 35 nodes is needed, refer to the information onassigning subnet addresses in Appendix A Use of Subnets on page 75.Table 7 Maximum Network CapabilitiesDevice Number of devices that can be maintained on oneAquaTrend Interface NetworkSignal Output Module (SOM) 8Serial I/O Module (SIO) 2Digital Display Module (DDM) 8Sensors (A SIM is seen by the network as a sensor.Maximum sensors + SIMs = 8) 8AquaTrend Interface 1 Master, 8 Remotes |
