Isicelo

I-CPU 315-2 DP iyi-CPU enenkumbulo yohlelo ephakathi nendawo ukuya enkulu kanye ne-PROFIBUS DP master/slave interface. Isetshenziswa ezitshalweni eziqukethe izakhiwo ezizenzakalelayo ezisabalalisiwe ngaphezu kwe-I/O emaphakathi.

Ivame ukusetshenziswa njenge-standard-PROFIBUS DP master ku-SIMATIC S7-300. I-CPU ingasetshenziswa futhi njenge-distributed intelligence (DP isigqila).

Ngenxa yobuningi bezakhiwo zazo, zilungele ukusetshenziswa kwamathuluzi obunjiniyela be-SIMATIC, isb:

Ukwenza izinhlelo nge-SCL

Isinyathelo sokuhlela izinhlelo nge-S7-GRAPH

Ngaphezu kwalokho, i-CPU iyinkundla ekahle yemisebenzi elula yezobuchwepheshe eyenziwe ngesoftware, isb:

Ukulawula ukunyakaza nge-Easy Motion Control

Ukuxazulula imisebenzi yokulawula iluphu evaliwe kusetshenziswa amabhulokhi we-STEP 7 noma isoftware yokulawula yesikhathi sokusebenza ejwayelekile/yemojula ye-PID

Ukuxilongwa kwenqubo okuthuthukisiwe kungafinyelelwa ngokusebenzisa i-SIMATIC S7-PDIAG.

Idizayini

I-CPU 315-2 DP ifakwe lokhu okulandelayo:

I-Microprocessor;

iphrosesa ifinyelela isikhathi sokucubungula esingaba ngu-50 ns ngomyalelo kanambambili ngamunye kanye no-0.45 µs ngokusebenza kwendawo ngayinye entantayo.

256 KB inkumbulo yomsebenzi (ihambisana nemiyalelo elinganiselwa ku-85 K);

inkumbulo ebanzi yomsebenzi yezigaba zohlelo ezihambisana nokusebenza inikeza isikhala esanele sezinhlelo zabasebenzisi. I-SIMATIC Micro Memory Cards (8 MB ubukhulu) njengememori yokulayisha yohlelo futhi avumela iphrojekthi ukuthi igcinwe ku-CPU (igcwele izimpawu namazwana) futhi ingasetshenziselwa ukugcinwa kwedatha nokuphathwa kweresiphi.

Amandla okwandisa aguquguqukayo;

ubuningi. 32 amamojula (4-tier ukucushwa)

Isikhombikubona se-MPI samaphuzu amaningi;

isixhumi esibonakalayo se-MPI esihlanganisiwe singasungula ukuxhumana okufika ku-16 ngesikhathi esisodwa ku-S7-300/400 noma ukuxhumana namadivayisi wokuhlela, ama-PC, ama-OP. Kulokhu kuxhumana, okukodwa kuhlala kugcinelwe amadivayisi wokuhlela kanti okunye kugcinelwe ama-OP. I-MPI yenza kube nokwenzeka ukumisa inethiwekhi elula enenani eliphezulu lama-CPU angu-16 ngokusebenzisa "ukuxhumana kwedatha yomhlaba wonke".

PROFIBUS DP interface:

I-CPU 315-2 DP ene-PROFIBUS DP master/slave interface ivumela ukucushwa okuzenzakalelayo okusabalalisiwe okunikeza isivinini esikhulu nokusebenziseka kalula. Ngokombono womsebenzisi, ama-I/O asabalalisiwe aphathwa ngendlela efanayo nama-I/O amaphakathi (ukucushwa okufanayo, ikheli kanye nezinhlelo).

Izinga le-PROFIBUS DP V1 lisekelwa ngokugcwele. Lokhu kuthuthukisa ikhono lokuxilonga kanye nepharamitha yezigqila ezijwayelekile ze-DP V1.

Umsebenzi

Ukuvikelwa kwephasiwedi;

umqondo wephasiwedi uvikela uhlelo lomsebenzisi ekufinyeleleni okungagunyaziwe.

Vimba ukubethela;

amafunctions (ama-FC) nama-function blocks (ama-FB) angagcinwa ku-CPU ngendlela ebethelwe kusetshenziswa i-S7-Block Privacy ukuze kuvikelwe ulwazi lohlelo lokusebenza.

Ibhafa yokuxilonga;

iphutha lokugcina elingu-500 nemicimbi ephazamisayo igcinwa kusigcinalwazi ngezinjongo zokuxilonga, ezingu-100 zazo zigcinwa ngokugcinwa.

Isipele sedatha samahhala;

i-CPU igcina ngokuzenzakalelayo yonke idatha (kufika ku-128 KB) uma kwenzeka ukwehluleka kwamandla ukuze idatha itholakale futhi ingashintshiwe lapho amandla ebuya.
