  We de­scribe the sta­tus of the DANTE (DA¿NE New Tools En­vi­ron­ment) con­trol sys­tem for the new DA{Φ}NE {Φ}-fac­tory under con­struc­tion at the Fras­cati Na­tional Lab­o­ra­to­ries. The sys­tem is based on a cen­tral­ized com­mu­ni­ca­tion ar­chi­tec­ture for sim­plic­ity and re­li­a­bil­ity. A cen­tral proces­sor unit co­or­di­nates all com­mu­ni­ca­tions be­tween the con­soles and the lower level dis­trib­uted pro­cess­ing power, and con­tin­u­ously up­dates a cen­tral mem­ory that con­tains the whole ma­chine sta­tus. We have de­vel­oped a sys­tem of VME Fiber Optic in­ter­faces al­low­ing very fast point to point com­mu­ni­ca­tion be­tween dis­tant proces­sors. Mac­in­tosh II per­sonal com­put­ers are used as con­soles. The lower lev­els are all built using the VME stan­dard.
