Overview
Iyo CPU ine yepakati kusvika kuhombe chirongwa chekuyeuka uye huwandu hwezvimiro zvekushandisa sarudzo yeSIMATIC engineering maturusi
High processing simba mubhinari uye inoyangarara-point arithmetic
Inoshandiswa sepakati controller mumitsetse yekugadzira ine nechepakati uye yakagovaniswa I/O
PROFIBUS DP tenzi / muranda interface
Nokuda kwekuwedzera kweI/O
Zvekugadzirisa zvakagoverwa I/O zvimiro
Isochronous mode paPROFIBUS
SIMATIC Micro Memory Kadhi inodiwa pakushanda kweCPU.
Application
Iyo CPU 315-2 DP iCPU ine yepakati-saizi kune yakakura chirongwa ndangariro uye PROFIBUS DP tenzi / muranda interface. Inoshandiswa muzvirimwa zvine akagovaniswa otomatiki zvimiro mukuwedzera kune yepakati I/O.
Inowanzoshandiswa seyakajairwa-PROFIBUS DP tenzi muSIMATIC S7-300. Iyo CPU inogona zvakare kushandiswa seyakagoverwa njere (DP muranda).
Nekuda kwehuwandu hwezvimiro, iwo akanakira kushandiswa kweSIMATIC engineering maturusi, semuenzaniso:
Kuronga neSCL
Machining nhanho chirongwa neS7-GRAPH
Uyezve, iyo CPU ipuratifomu yakanakira yezvakareruka software-yakaiswa tekinoroji mabasa, semuenzaniso:
Motion control ne Easy Motion Control
Kugadziriswa kweakavharika-loop kutonga mabasa uchishandisa STEP 7 zvidhinha kana yakajairwa/modular PID control runtime software.
Enhanced process diagnostics inogona kuwanikwa nekushandisa SIMATIC S7-PDIAG.
Design
Iyo CPU 315-2 DP ine zvinotevera:
Microprocessor;
iyo processor inowana nguva yekugadzirisa inosvika makumi mashanu ns pamurairo webhinari uye 0.45 µs pairi inoyangarara-nzvimbo kushanda.
256 KB ndangariro yebasa (inofambirana neanenge 85 K mirairo);
iyo yakakura yekurangarira yebasa yezvikamu zvechirongwa zvinoenderana nekuita inopa nzvimbo yakakwana yezvirongwa zvemushandisi. SIMATIC Micro Memory Cards (8 MB max.) semutoro wekuyeuka wechirongwa zvakare unobvumira purojekiti kuti ichengetwe muCPU (izere nezviratidzo uye makomendi) uye inogona kushandiswa kuchengetedza data uye resipi manejimendi.
Flexible kuwedzera kugona;
max. 32 modules (4-tier kumisikidza)
MPI multi-point interface;
iyo yakabatanidzwa MPI interface inogona kumisikidza akawanda segumi nematanhatu ekubatanidza panguva imwe chete kuS7-300/400 kana kubatanidza kune zvirongwa zvekugadzira, maPC, OPs. Pane izvi zvinongedzo, imwe inogara yakachengeterwa midziyo yekuronga uye imwe yeOPs. Iyo MPI inoita kuti zvikwanise kumisikidza network yakapusa ine inokwana gumi nematanhatu CPUs kuburikidza ne "global data communication".
PROFIBUS DP interface:
Iyo CPU 315-2 DP ine PROFIBUS DP tenzi / muranda interface inobvumira yakagoverwa otomatiki gadziriso inopa kumhanya kwakanyanya uye nyore kushandisa. Kubva pamaonero emushandisi, maI/O akagoverwa anobatwa zvakafanana nepakati I/Os (yakafanana gadziriso, kero uye hurongwa).
Iyo PROFIBUS DP V1 chiyero inotsigirwa zvizere. Izvi zvinowedzera kuongororwa uye parameterization kugona kweDP V1 yakajairwa varanda.
Function
Kudzivirira pasiwedhi;
chirevo chepassword chinodzivirira chirongwa chemushandisi kubva kusingabvumirwe kuwana.
Block encryption;
Iwo mabasa (FCs) uye mabhuroki emabasa (FBs) anogona kuchengetwa muCPU mune encrypted fomu nenzira yeS7-Block Kuvanzika kuchengetedza kuziva-kuita kwechishandiso.
Diagnostics buffer;
iyo yekupedzisira 500 kukanganisa uye kukanganisa zviitiko zvakachengetwa mubuffer nekuda kwekuongorora, iyo zana inochengetwa yakachengetedzwa.
Kuchengetedza-yemahara data backup;
iyo CPU inongochengetedza data rese (kusvika ku128 KB) kana ikatadza simba kuitira kuti data riwanikwe zvakare risina kuchinjwa kana simba radzoka.
