  Dur­ing the last two years, trig­gered by the con­struc­tion of the XRD2 beam­line, and to com­ply with the top-up op­er­a­tions, a com­plete re­fur­bish­ment of the Elet­tra Super Con­duct­ing Wig­gler (SCW) has been car­ried out. Along­side with the me­chan­i­cal, cryo­genic and elec­tri­cal com­po­nents, also the elec­tron­ics, the con­trol and in­ter­lock sys­tems have been up­graded. The MVME5110 Pow­erPC sin­gle board com­puter, which is a stan­dard in the Elet­tra con­trol sys­tem, has been adopted, as well as RS232 com­mu­ni­ca­tion mod­ules, ana­log to dig­i­tal con­vert­ers and dig­i­tal I/O lines. In order to cope with the high out­put power of the SCW, up to18 KW, the in­ter­lock sys­tem, pro­tect­ing both the wig­gler and the beam­line front-end, has been com­pletely re­designed. The con­trol sys­tem soft­ware has been re-writ­ten from scratch using the TANGO soft­ware frame­work. The com­plete sys­tem has been tested dur­ing the sec­ond half of 2014 and is now fully op­er­a­tional.
