Field­bus­es in In­dus­tri­al En­vi­ron­ments

PROFIBUS AND PROFINET

Thanks to their mod­u­lar de­sign, IFTA mea­sure­ment sys­tems can be flex­i­bly in­te­grat­ed into ex­ist­ing pro­cess­es and net­works. Data ex­change be­tween the IFTA mea­sure­ment sys­tem and the plant con­trol sys­tem is im­por­tant for the smooth op­er­a­tion of the plant. If the com­mu­ni­ca­tion stan­dards PROFIBUS or PROFINET are used here, the fol­low­ing mod­ules are suit­able for send­ing and re­ceiv­ing data.

What is PROFIBUS and PROFINET and what is the dif­fer­ence?

PROFIBUS and PROFINET are com­mu­ni­ca­tion stan­dards for the safe au­to­ma­tion of plants. PROFIBUS is an es­tab­lished com­mu­ni­ca­tion stan­dard and, like PROFINET, is de­vel­oped by the user or­ga­ni­za­tion PI. PROFINET is a fur­ther de­vel­op­ment of PROFIBUS based on in­dus­tri­al Eth­er­net. PROFINET of­fers ad­van­tages such as more bus par­tic­i­pants, high­er trans­mis­sion speed as well as larg­er data pack­ages.

Fieldbus IFTA PROFIBUS

Profibus

  • Com­mu­ni­ca­tion mod­ule for data input and out­put

Fieldbus IFTA PROFINET

PROFINET

  • Com­mu­ni­ca­tion mod­ule for data input and out­put
  • Based on the PROFINET field­bus pro­to­col for in­dus­tri­al Eth­er­net

High­lights

  • Com­mu­ni­ca­tion mod­ule for fast and se­cure data ex­change with a PROFIBUS mas­ter
  • Based on the PROFIBUS field­bus pro­to­col: PROFIBUS is a stan­dard­ized, open, dig­i­tal com­mu­ni­ca­tion sys­tem for any ap­pli­ca­tions in man­u­fac­tur­ing and process au­to­ma­tion
  • Two re­dun­dant PROFIBUS slaves for max­i­mum re­li­a­bil­i­ty
  • DP-V0 slave
  • Trans­fer of up to 244 bytes of I/O data
  • Via the Sig­nalMin­er soft­ware you can freely de­fine which sig­nals are to be sent and re­ceived. On the one hand, you can send e.g. warn­ing and alarm mes­sages but also am­pli­tudes. On the other hand, you can re­ceive op­er­at­ing data as well as limit val­ues and ma­chine states

Ad­van­tages of the PROFIBUS Tech­nol­o­gy

  • PROFIBUS is one of the most uni­ver­sal so­lu­tions in the field of process au­to­ma­tion
  • PROFInet, PROFIsafe PROFI­drive and many other vari­ants can be in­tu­itive­ly con­nect­ed via cor­re­spond­ing gate­ways, so you are well-equipped for the most di­verse re­quire­ments

Profinet beN­e­fits COMPARED TO Profibus

  • PROFINET is the more mod­ern tech­nol­o­gy and eas­i­er to con­nect
  • Sig­nif­i­cant­ly high­er trans­mis­sion rate and thus faster com­mu­ni­ca­tion
  • In­te­grat­ed 2-port switch for easy lin­ear topol­o­gy ca­bling
  • PROFINET sup­ports the Media Re­dun­dan­cy Pro­to­col (MRP), which en­ables ring topol­o­gy ca­bling for high­er re­li­a­bil­i­ty
