Isicelo
I-CPU 315-2 DP yi-CPU ene-medium-size ukuya kwimemori yeprogram enkulu kunye ne-PROFIBUS DP master / interface yamakhoboka. Isetyenziswe kwizityalo eziqulethe izakhiwo ezizenzekelayo ezisasazwayo ngaphezu kwe-I / O ephakathi.
Ihlala isetyenziswa njenge-standard-PROFIBUS DP master kwi-SIMATIC S7-300. I-CPU ingasetyenziselwa njengengqondo esasazwayo (ikhoboka le-DP).
Ngenxa yobuninzi bezakhiwo zabo, zilungele ukusetyenziswa kwezixhobo zobunjineli be-SIMATIC, umzekelo:
Ukucwangcisa nge-SCL
Inyathelo lokucwangcisa inkqubo nge-S7-GRAPH
Ngaphaya koko, i-CPU liqonga elifanelekileyo lemisebenzi elula yetekhnoloji eyenziwe ngesoftware, umzekelo:
Ulawulo lwentshukumo nge Easy Motion Control
Ukusonjululwa kwemisebenzi yolawulo lwe-loop evaliweyo usebenzisa i-STEP 7 iibhloko okanye i-standard/modyuli ye-PID yokulawula isoftware
Ukuxilongwa kwenkqubo ephuculweyo kunokufezekiswa ngokusebenzisa i-SIMATIC S7-PDIAG.
Yila
I-CPU 315-2 DP ixhotyiswe ngoku kulandelayo:
Microprocessor;
umqhubekekisi uphumeza ixesha lokuqhubekeka elimalunga nama-50 ns ngomyalelo wokubini kunye ne-0.45 µs kwindawo nganye edadayo.
256 KB inkumbulo yomsebenzi (ihambelana nemiyalelo emalunga nama-85 K);
Inkumbulo yomsebenzi ebanzi yamacandelo enkqubo ehambelana nokuphunyezwa inika indawo eyaneleyo yeenkqubo zabasebenzisi. I-SIMATIC Micro Memory Cards (8 MB max.) njengememori yomthwalo weprogram kwakhona ivumela iprojekthi ukuba igcinwe kwi-CPU (izaliswe ngeesimboli kunye nezimvo) kwaye ingasetyenziselwa ukugcinwa kwedatha kunye nolawulo lweresiphi.
Ikhono lokwandisa eliguquguqukayo;
max. Iimodyuli ezingama-32 (uqwalaselo lwenqanaba eli-4)
Ujongano lwamanqaku amaninzi eMPI;
i-interface ye-MPI edibeneyo inokuseka ezininzi njenge-16 uxhulumaniso ngaxeshanye ukuya kwi-S7-300/400 okanye ukudityaniswa kwezixhobo zokucwangcisa, iiPC, ii-OP. Kolu qhagamshelo, enye isoloko igcinelwe izixhobo zokucwangcisa kunye nenye yee-OPs. I-MPI yenza kube lula ukuseka inethiwekhi elula kunye nobuninzi be-16 CPU ngokusebenzisa "unxibelelwano lwedatha yehlabathi".
PROFIBUS DP ujongano:
I-CPU 315-2 DP kunye ne-PROFIBUS DP master / ujongano lwekhoboka ivumela ulungelelwaniso oluzenzekelayo olusasazwayo olunikezela ngesantya esiphezulu kunye nokulula kokusetyenziswa. Ukususela kumbono womsebenzisi, i-I / Os esasazwayo iphathwa ngokufanayo ne-I / Os ephakathi (ubumbeko olufanayo, idilesi kunye neprogram).
Umgangatho wePROFIBUS DP V1 uxhaswa ngokupheleleyo. Oku kwandisa isakhono sokuxilonga kunye neparameterisation ye-DP V1 yamakhoboka asemgangathweni.
Umsebenzi
ukhuseleko lwegama lokugqithisa;
Igama lokugqitha likhusela inkqubo yomsebenzisi kunikezelo olungagunyaziswanga.
Uguqulelo oluntsonkothileyo
imisebenzi (FCs) kunye neebhloko zemisebenzi (FBs) zinokugcinwa kwi-CPU ngendlela efihliweyo nge-S7-Block yaBucala ukukhusela ulwazi lwesicelo.
Isithinteli soxilongo;
impazamo yokugqibela ye-500 kunye neziganeko zokuphazamiseka zigcinwa kwi-buffer ngeenjongo zokuxilonga, apho i-100 igcinwa ngokugcinwa.
Ugcino lwasimahla lwedatha yedatha;
i-CPU igcina ngokuzenzekelayo yonke idatha (ukuya kwi-128 KB) kwimeko yokusilela kwamandla ukuze idatha ifumaneke kwakhona ingatshintshanga xa umbane ubuya.
