The Pro­ces­sor for Real-Time Anal­y­sis

Stable and re­li­able data pro­cess­ing is the basis/foun­da­tion of the IFTA plat­form's suc­cess. A dig­i­tal sig­nal pro­ces­sor (DSP) pro­cess­es high-res­o­lu­tion vi­bra­tion data in real-time with the IFTA Sig­nalMin­er firmware using the so-called Fast Fouri­er Trans­for­ma­tion (FFT). This level in the IFTA sys­tem does not re­quire an op­er­at­ing sys­tem and there­fore guar­an­tees 24/7 pro­tec­tion and op­er­a­tion. After a power fail­ure, the DSP starts au­tonomous­ly using the firmware and con­fig­u­ra­tion last stored in its flash mem­o­ry and re­sumes its work after a few sec­onds.

Real-Time Ca­pa­bil­i­ty for High Plant Avail­abil­i­ty

The IFTA sys­tems are based on a dig­i­tal sig­nal pro­ces­sor for sig­nal anal­y­sis. This al­lows the de­ter­min­is­tic run­time of com­mands nec­es­sary for pro­tec­tion sys­tems with real-time ca­pa­bil­i­ty in in­dus­tri­al en­vi­ron­ments. The ca­pa­bil­i­ty for real-time pro­cess­ing is es­pe­cial­ly im­por­tant in pro­tec­tion as it pro­vides high avail­abil­i­ty of ma­chines or plants. Op­ti­mized al­go­rithms en­sure short anal­y­sis times. Spec­tra with up to 6400 lines cal­cu­lat­ed live per chan­nel are the most im­por­tant ex­am­ple for this. The eval­u­a­tion soft­ware IFTA TrendView­er can di­rect­ly vi­su­al­ize data pre-cal­cu­lat­ed by the DSP.

Sig­nal Pro­cess­ing Unit IFTA DSP V3.1 for Real-Time Data Anal­y­sis

  • Overview
  • Tech­ni­cal Data
  • Op­tions

The IFTA sys­tems base on a sig­nal pro­ces­sor for sig­nal anal­y­sis - the IFTA DSP. By means of the firmware IFTA Sig­nalMin­er it pro­vides real-time pro­cess­ing of input sig­nals and out­put of anal­y­sis re­sults. The ca­pa­bil­i­ty for real-time is in par­tic­u­lar re­quired when pro­tect­ing in­dus­tri­al plants, as it en­sures fast pro­cess­ing of sig­nals and high avail­abil­i­ty. For data stor­age and changes in con­fig­u­ra­tion the DSP com­mu­ni­cates via net­work with the IFTA DataHub soft­ware on an IFTA PanelPC, IFTA SlotPC or a work­sta­tion.


  • Real-time data anal­y­sis and pro­tec­tion
  • Stand-alone op­er­a­tion - pro­tec­tion func­tions are fully func­tion­al even with­out PC since con­fig­u­ra­tion and firmware are lo­cat­ed on a flash stor­age and con­se­quent­ly the mod­ule starts with­out a PC
  • High ac­cu­ra­cy real-time clock that en­sures a pre­cise time stamp for all ac­quired sig­nals. For track­ing the DSP syn­chro­nizes its clock with the PC
  • Sam­pling rate up to 102.4 kHz with up to 32 chan­nels
  • Sup­ports PROFIBUS field bus com­mu­ni­ca­tion
  • 6 Sta­tus LEDs
  • Mon­i­tor­ing of all in­stalled mod­ules with­in the same rack in­clud­ing tem­per­a­tures
  • Micro USB-C port for main­te­nance (firmware up­grades und log­ging)
