Isicelo

I-CPU 315-2 DP yi-CPU enosayizi ophakathi nendawo kwimemori yohlelo enkulu kanye ne-Profibus DP Master / interface yenceku. Isetshenziswa ezitshalweni eziqukethe izakhiwo ezihambisanayo ezisatshalaliswa ngaphezu kwe / O.

Imvamisa isetshenziswa njenge-standard-Profibus DP master in simatic s7- 300. I-CPU nayo ingasetshenziswa njengobuhlakani obusatshalaliswa (isigqila se-DP).

Ngenxa yezakhiwo zazo eziningi, zilungele ukusetshenziswa kwamathuluzi wobunjiniyela be-simatic, isib:

Ukuhlelwa nge-SCL

Ukuhlelwa kwemishini kwensiza nge-S7-graph

Ngaphezu kwalokho, i-CPU iyipulatifomu efanelekile yemisebenzi elula yezobuchwepheshe esetshenziswayo yesoftware, isib:

Ukulawula ukunyakaza ngokulawulwa okulula kwe-Motion

Ukuxazululwa kwemisebenzi yokulawula evaliwe ye-Loop usebenzisa Isinyathelo 7 Amabhlogo noma isoftware ejwayelekile ye-PID yokulawula

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

Ukusongoza icebo

I-CPU 315-2 DP ifakwe okulandelayo:

I-Microprocessor;

I-processor ifinyelela isikhathi sokucubungula cishe ama-50 ns ngomyalo kanambambili kanye nama-0.45 μs ngokusebenza kwamaphuzu antantayo.

Imemori yomsebenzi we-256 KB (ihambelana ne-approx. 85 k Imiyalo);

Imemori yomsebenzi ebanzi yezingxenye zoHlelo ezihambelana nokwenza izinto ezanele zezinhlelo zomsebenzisi. I-Simatic Memory Cards Cards (8 MB Max.) Njengoba imemori yokulayisha yohlelo futhi ivumela iphrojekthi ukuthi igcinwe kwi-CPU (ephelele ngezimpawu namazwana) futhi ingasetshenziselwa ukuphathwa kwedatha nokuphatha idatha.

Amandla okukhanya okuguquguqukayo;

UMax. Amamojula angama-32 (ukucushwa kwe-4-tier)

Isikhombimsebenzisi esibonakalayo se-MPI;

Isixhumi esihlanganisiwe se-MPI singasungula ukuxhumeka okuningi okungu-16 ngasikhathi sinye ku-S7-300 / 400 noma ukuxhumana kumadivayisi wokuhlela, ama-PC, OPS. Kulezi zixhumanisi, umuntu uhlala ebekelwe amadivaysi okuhlela kanti omunye ngama-ops. I-MPI yenza kube nokwenzeka ukusetha inethiwekhi elula enesilinganiso esingu-16 CPU nge "Ukuxhumana kwedatha yomhlaba".

Isikhombi esibonakalayo se-Profibus DP:

I-CPU 315-2 DP ene-Profibus DP Master / interface yenceku ivumela ukucushwa okusatshalaliswa okusatshalaliswa okunikezela ngejubane eliphezulu kanye nokusebenziseka kalula. Ukusuka endaweni yokubuka yomsebenzisi, okusatshalaliswa i / os kuphathwa okufanayo ne-Central I / OS (ukucushwa okufanayo, ukubhekana nohlelo).

I-Profibus DP V1 ejwayelekile isekelwa ngokugcwele. Lokhu kuthuthukisa amandla okuxilonga kanye namapharamende e-DP v1 izigqila ezijwayelekile.

Sebenza

Ukuvikelwa kwephasiwedi;

Umqondo wephasiwedi uvikela uhlelo lomsebenzisi ekufinyeleleni okungagunyaziwe.

Vimba ukubethela;

Imisebenzi (ama-FCS) kanye namabhulokhi okusebenza (ama-FBS) angagcinwa kwi-CPU kwifomu elibethelwe nge-S7-block Ubumfihlo ukuvikela ulwazi.

Ukuxilonga i-buffer;

Iphutha lokugcina lama-500 nemicimbi ephazamisayo igcinwa ku-buffer ngezinjongo zokuxilonga, okuyi-100 zigcinwa ngokubuyiselwa emuva.

Isipele sedatha yamahhala;

I-CPU igcina yonke imininingwane (kufika ku-128 kb) uma kwenzeka ukwehluleka kwamandla ukuze imininingwane iphinde itholakale futhi ingashintshiwe lapho amandla ebuya.
