FX3U a new PLC concept /// FX3U a new PLC concept /// FX3U a new PLCThe FX3U has an enhancedcommunications bus that automaticallyswitches into high speed mode forcommunication with new FX3U expansionmodules.Full compatibility is still available withFX2N and FX0N expansion blocks, andwhen these are configured the FX3Uautomatically reduces the bus speed tosuit.This means greater support for existinginstalled systems as well as delivering highperformance and greater response withnew installations.Adapters addflexibilityFX3U a newPLC conceptA major design enhancement of FX3U isthe new adapter expansion bus on the lefthand side of the FX3U CPU. Through thisbus users can add additional analog andtemperature units as well as multiplecommunications and positioning blocks.The new FX3U CPU brings a combinationof greater flexibility and increasedperformance to the FX Family.New highspeed busThe FX3U design has increased theopportunity to configure the PLC directlyfor your needs.Following the standard FX Familyconfiguration, the FX3U CPU can beexpanded to the right hand side using awide range of options. These include inputand output blocks as well as specialfunction blocks such as analog, pulse trainand network communication units.FX3U has a unique new system of directlyprogrammable adapters.However, the major benefit for the user isthat the analog and positioning adapterunits no longer require the use of thetraditional To/From instruction toconfigure and operate.All control is through direct access dataregisters and setting bits. This meansquicker set-up, easier use, and above allmuch higher processing speeds.The FX3U can use new FX3U blocks as well asstandard FX2N and FX0N expansion blocks..7
