Mwachidule
CPU yokhala ndi kukumbukira kwapakatikati mpaka yayikulu komanso kuchuluka kwazinthu zogwiritsa ntchito mwakufuna kwa zida zaukadaulo za SIMATIC
Mphamvu yayikulu yopangira masamu a binary ndi zoyandama
Amagwiritsidwa ntchito ngati wolamulira wapakati pamizere yopanga yokhala ndi I/O yapakati komanso yogawidwa
PROFIBUS DP mbuye / kapolo mawonekedwe
Kuti muwonjezere I/O
Kuti mukonze zida za I/O zogawidwa
Isochronous mode pa PROFIBUS
SIMATIC Micro Memory Card yofunikira kuti CPU igwire ntchito.
Kugwiritsa ntchito
CPU 315-2 DP ndi CPU yokhala ndi kukumbukira kwapakatikati mpaka kwakukulu ndi mawonekedwe a PROFIBUS DP master/akapolo. Amagwiritsidwa ntchito muzomera zomwe zimakhala ndi makina opangira makina ophatikizira kuphatikiza I/O yapakati.
Nthawi zambiri amagwiritsidwa ntchito ngati master-PROFIBUS DP master mu SIMATIC S7-300. CPU itha kugwiritsidwanso ntchito ngati distributed intelligence (DP slave).
Chifukwa cha kuchuluka kwake, ndiabwino kugwiritsa ntchito zida zaukadaulo za SIMATIC, mwachitsanzo:
Kupanga mapulogalamu ndi SCL
Kukonzekera masitepe ndi S7-GRAPH
Kuphatikiza apo, CPU ndi nsanja yabwino yopangira ntchito zosavuta zaukadaulo zamapulogalamu, mwachitsanzo:
Kuwongolera koyenda ndi Easy Motion Control
Kuthetsa ntchito zowongolera zotsekeka pogwiritsa ntchito midadada ya STEP 7 kapena pulogalamu yokhazikika/modular PID control runtime
Njira zowunikira zowonjezera zitha kukwaniritsidwa pogwiritsa ntchito SIMATIC S7-PDIAG.
Kupanga
CPU 315-2 DP ili ndi izi:
Microprocessor;
purosesa imakwaniritsa nthawi yokonza pafupifupi 50 ns pa malangizo a binary ndi 0.45 µs pa ntchito yoyandama.
256 KB kukumbukira ntchito (kumagwirizana ndi pafupifupi 85 K malangizo);
kukumbukira kwakukulu kwa ntchito zamagawo okhudzana ndi kuphedwa kumapereka malo okwanira kwa mapulogalamu a ogwiritsa ntchito. SIMATIC Micro Memory Cards (8 MB max.) monga kukumbukira katundu wa pulogalamuyi amalolanso kuti polojekitiyi isungidwe mu CPU (yodzaza ndi zizindikiro ndi ndemanga) ndipo ingagwiritsidwe ntchito posungira deta ndi kuyang'anira maphikidwe.
Flexible kukulitsa luso;
max. 32 modules (4-tier kasinthidwe)
MPI multi-point mawonekedwe;
mawonekedwe ophatikizika a MPI amatha kukhazikitsa zolumikizira 16 nthawi imodzi ku S7-300/400 kapena kulumikizana ndi zida zamapulogalamu, ma PC, ma OP. Mwa maulumikizidwe awa, imodzi imasungidwa pazida zamapulogalamu ndipo ina ya OPs. MPI imapangitsa kuti zitheke kukhazikitsa maukonde osavuta okhala ndi ma CPU opitilira 16 kudzera pa "kulumikizana kwa data padziko lonse lapansi".
PROFIBUS DP mawonekedwe:
CPU 315-2 DP yokhala ndi PROFIBUS DP master/akapolo mawonekedwe imalola kasinthidwe kazinthu zodziwikiratu zomwe zimapereka liwiro lalikulu komanso zosavuta kugwiritsa ntchito. Kuchokera pamawonedwe a wogwiritsa ntchito, ma I / O omwe amagawidwa amachitidwa mofanana ndi ma I / Os apakati (makonzedwe ofanana, maadiresi ndi mapulogalamu).
Muyezo wa PROFIBUS DP V1 umathandizidwa mokwanira. Izi zimakulitsa luso lozindikira komanso lokhazikika la akapolo wamba a DP V1.
Ntchito
Chitetezo chachinsinsi;
mawu achinsinsi amateteza pulogalamu ya wosuta kuti asapezeke mosaloledwa.
Kubisa kwa block;
ntchito (FCs) ndi ma block block (FBs) zitha kusungidwa mu CPU m'njira yobisidwa pogwiritsa ntchito Zinsinsi za S7-Block kuteteza kudziwa kwa pulogalamuyi.
Diagnostics buffer;
zolakwika zomaliza za 500 ndi kusokoneza zochitika zimasungidwa mu buffer kuti zifufuze, zomwe 100 zimasungidwa mosalekeza.
Zosunga zobwezeretsera zopanda data;
CPU imasunga deta yonse (mpaka 128 KB) ngati mphamvu ikulephera kuti deta ipezekenso osasintha mphamvu ikabwerera.
