Forward-lookingmodular architecture

Growing demands ondecentralised automation

systems call for new, high-performance designs thatfacilitate system developmentand implementation. The newMELSEC ST is the synthesis ofall the key factors needed forsuccess:

● Extremely simple handlingcombined with high-techfunctions.

● Outstanding availability,service life and performanceunder heavy-dutyconditions.

● Efficient and trouble-free,from initial project planningto ongoing maintenance.

● Uses tried-and-tested, well-established terminaltechnology.

● Enables cost-effectiveimplementation of featuresand functions.

Horizontal or verticalconfigurations

Mitsubishi Electric has realisedall these requirements, pointfor point. The new MELSEC STprovides flexible configuration of up to 256 I/Os and 63slices in horizontal or verticalconfigurations. The fully-modu-lar architecture and 2-compo-nent connection technologyprovides a wealth of advan-tages and cost savings.

Slim design saves –the modules are just12.6mm thick, savingspace in your controlcabinet.

Snap-in technologyfor quick installationof the base modulesand firm seating onthe top-hat rail.

The power supplymodules provide the24V DC for all thebase modules and theinternal 5V DC for thebackplane bus.

Reliable datacommunications viathe head station withProfibus connection.

Status LEDs onevery electronicsmodule for fastand easydiagnostics.

Extremely precisegranularity

A granularity of 2 and 16 I/Oblock modules, permanentwiring and module hot-swapping during operationare just some of the strengthsof this system. MELSEC STconfigurations are installed,configured and operatedusing only familiar, tried-and-tested components, withoutadditional products.

Improvements for manyapplications

With its many benefits thenew MELSEC ST guarantees ahigh level of efficiencycombined with lower costs,both for simple tasks and inhighly-complex applicationssuch as those in the textilesindustry, paper processing,cardboard box and packagingtechnology, water treatmentand many other fields.

Fast, simple, precise:“Permanent” wiring forall available basemodules.

User BenefitsPoint for Point:The new MELSEC ST savestime and cuts costs

● Control cabinet: Just12.6mm thick, the modulesare the slimmest on themarket.

● I/Os: Block modules of 16with a 25% price saving; thegranularity is 2, with max. 1excess I/O point.

● Inventory: The modular headstation means just hardwaresolution for all present andfuture bus stations.

● On the market: Adaptationfor bus changes only calls forredevelopment for the headstation, ensuring shortestpossible time to market.

● Cabling and accessories:GX Configurator DP andQC30R2 don’t generate anyadditional costs.

● Engineering:GX Configurator DP includestools for everything fromconfiguration to diagnostics.

● Maintenance:Permanent wiringand hot swapping.

The new MELSEC ST is simple,trouble-free and reliable:

● The integrated terminals ofthe base modules eliminatesthe need for additionalterminal strips.

● Hot swapping at the press ofa key, no laptop or addi-tional software required.

● No need to disconnectwiring for servicing.

● Keyed modules makeincorrect insertion virtuallyimpossible.

● Fast diagnostics with statusLEDs on every module andat the node.

● Gold-plated contacts forhigh quality, availability andreliable connections.

● Tools integrated inGX Configurator DP.

● PE connection viatop-hat DIN rail.

● No active bus terminationrequired.

Highly functional with apractical, clear layout,the head station with itsProfibus interface is the“control centre” ofMELSEC ST.

Sixteen-point electronicsmodules with blockarchitecture for efficientinstallation and low costs.

The power supplymodules for the24V DC power can beconfigured precisely tomatch your I/O usage.

All base modules areavailable with eitherspring or screwterminals.

The PE connection iseffected automaticallyvia the top-hat DIN rail.

The Product Code –Precise Identification at a GlanceThe product code contains allthe information you need toselect the right module types(ST1…) for your application.

First the electronics modules:...P- for Power,...X- for Digital Inputs,...Y- for Digital Outputs,...AD- for Analog Inputs,...DA- for Analog Outputs

Then the base modules:...B- for Base

And finally the accessories:...A- for Accessories

The number of PDD powerinfeed modules required tosupply the power to the24V DC terminals leveldepends on the consumption

of the sensors and actuatorsin your system.

The number of PSD refreshmodules required for theinternal 5V DC bus iscalculated precisely for yourconfiguration by theGX-Configurator DP software

package. The following valuesprovide a rough guide forestimating the quantityrequired in advance:
