SMART DISTRIBUTED SYSTEM (SDS) I/O

OverviewIf you are already using or planning toimplement an SDS controllernetwork, using the F2-SDS-1 moduleand I/O sub-system can help reduce thecost of your overall application. TheSmart Distributed System (SDS)provides a means to connect automationequipment and devices on a singlenetwork, which eliminates expensivehardwiring. This standard communica-

tion media and software provides a low-cost method for controllers and devicesto communicate low-level data at highspeeds. The SDS standard provides spec-ifications for information exchangebetween nodes, as well as device-leveldiagnostics not normally found in otherI/O systems. The F2-SDS-1 moduleallows the well-proven micro-modularDL205 I/O system to be controlled byyour SDS master controller.

How it worksThe FS-SDS-1 module plugs into theCPU slot of any DL205 I/O base. Themodule maintains a database with allidentification data, diagnostic informa-tion, and parameters that are configured

within the base and control the opera-tion of the SDS slave module and theI/O. The F2-SDS-1 slave will monitorand report discrete and analog I/Omodule data to a SDS Master. All ACexternally-powered DL205 I/O base

units contain a 24VDC, 0.3A powersupply for simple wiring of sensors andactuators into the DL205 I/O modules,

and for controlling them with a SDSMaster. The F2-SDS-1 module supportsall DL205 discrete and analog I/Omodules. The SDS also offers:

Cost effectiveness: SDS offers inexpen-sive controller and industrial DL205I/O sub-system.

Easy connectivity: SDS is low-cost, itseasy to implement and maintain wiringsystem.

Innovative technology: Power is inte-grated into the device.

Diagnostics: SDS offers advanced errordiagnostics not commonly found intraditional systems.

High baud rates: Baud rate bringresponse time down to 0.10ms perdevice.

LED indicators: Provides indication ofDL205 Smart Distributed System.
