Isicelo

I-CPU 315-2 DP iyi-CPU enenkumbulo yohlelo ephakathi nendawo kuya kwenkulu kanye ne-PROFIBUS DP master/slave interface. Isetshenziswa ezitshalweni eziqukethe izakhiwo zokwenza izinto ngokuzenzakalelayo ezisatshalaliswe ngaphezu kwe-I/O ephakathi.

Ivame ukusetshenziswa njenge-standard-PROFIBUS DP master ku-SIMATIC S7-300. I-CPU ingasetshenziswa futhi njengobuhlakani obusabalalisiwe (i-DP slave).

Ngenxa yezakhiwo zazo zobuningi, zilungele ukusetshenziswa kwamathuluzi obunjiniyela be-SIMATIC, isib.

Ukuhlela nge-SCL

Ukuhlela isinyathelo somshini nge-S7-GRAPH

Ngaphezu kwalokho, i-CPU iyipulatifomu efanelekile yemisebenzi elula yezobuchwepheshe esetshenziswa yisoftware, isib.

Ukulawula Ukunyakaza Ngokulawula Ukunyakaza Okulula

Ukuxazulula imisebenzi yokulawula evaliwe kusetshenziswa amabhlogo e-STEP 7 noma isofthiwe yokusebenza yesikhathi sokulawula i-PID ejwayelekile/eyi-modular

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

Umklamo

I-CPU 315-2 DP ifakwe okulandelayo:

Iprosesa encane;

iprosesa ifinyelela isikhathi sokucubungula esingaba ngu-50 ns ngomyalelo ngamunye we-binary kanye no-0.45 µs ngokusebenza kwe-floating-point.

Imemori yokusebenza engu-256 KB (ihambisana nemiyalelo engaba ngu-85 K);

Imemori ebanzi yomsebenzi yezigaba zohlelo eziphathelene nokusebenza inikeza isikhala esanele sezinhlelo zomsebenzisi. Amakhadi Ememori Amancane e-SIMATIC (ubuningi obungu-8 MB) njengememori yomthwalo wohlelo futhi avumela iphrojekthi ukuthi igcinwe ku-CPU (iphelele ngezimpawu namazwana) futhi ingasetshenziswa ekugcinweni kwedatha kanye nokuphathwa kweresiphi.

Amandla okunweba aguquguqukayo;

amamojula angu-32 aphezulu (ukucushwa kwezinga eli-4)

isikhombikubona samaphuzu amaningi se-MPI;

isikhombikubona se-MPI esihlanganisiwe singasungula ukuxhumana okungafika ku-16 ngesikhathi esisodwa ku-S7-300/400 noma ukuxhumana namadivayisi okwenza izinhlelo, ama-PC, ama-OP. Kulokhu kuxhumana, okukodwa kuhlala kugcinelwe amadivayisi okwenza izinhlelo kanti okunye kugcinelwe ama-OP. I-MPI yenza kube nokwenzeka ukusetha inethiwekhi elula enama-CPU angu-16 ngokuxhumana kwedatha yomhlaba wonke.

Isixhumi esibonakalayo se-PROFIBUS DP:

I-CPU 315-2 DP ene-PROFIBUS DP master/slave interface ivumela ukucushwa okuzenzakalelayo okusatshalaliswa okunikeza isivinini esikhulu kanye nokulula kokusetshenziswa. Ngokombono womsebenzisi, ama-I/O asatshalaliswa aphathwa ngendlela efanayo ne-I/Os ephakathi (ukucushwa okufanayo, ikheli kanye nokuhlela).

Izinga le-PROFIBUS DP V1 lisekelwa ngokugcwele. Lokhu kuthuthukisa ikhono lokuxilonga kanye nokulinganisa ama-slave ajwayelekile e-DP V1.

Umsebenzi

Ukuvikelwa kwephasiwedi;

umqondo wephasiwedi uvikela uhlelo lomsebenzisi ekufinyeleleni okungagunyaziwe.

Ukubethela kwe-block;

imisebenzi (ama-FC) kanye namabhulokhi omsebenzi (ama-FB) angagcinwa ku-CPU ngendlela ebethelwe ngokusebenzisa i-S7-Block Privacy ukuvikela ulwazi lohlelo lokusebenza.

I-buffer yokuxilonga;

Imicimbi yokugcina yephutha engu-500 kanye nokuphazamiseka igcinwa ku-buffer ngezinjongo zokuxilonga, lapho engu-100 igcinwa khona ngokugcinwa.

Ukusekela idatha ngaphandle kokulungisa;

i-CPU igcina ngokuzenzakalelayo yonke idatha (kufika ku-128 KB) uma kwenzeka ugesi uphela ukuze idatha itholakale futhi ingashintshi lapho ugesi ubuya.
