SIEMENS 6ES7315-2AH14-0AB0 SIMATIC S7-300 CPU 315-2DP

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. Imagwiritsidwa ntchito muzomera zomwe zili ndi zida zogawira makina kuphatikiza ndi 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.
