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

Chidule

CPU yokhala ndi kukumbukira kwapakati mpaka kwakukulu kwa pulogalamu komanso kapangidwe ka kuchuluka kwa mapulogalamu kuti mugwiritse ntchito zida zaukadaulo za SIMATIC mwakufuna kwanu

Mphamvu yogwiritsira ntchito kwambiri mu masamu a binary ndi floating-point

Amagwiritsidwa ntchito ngati chowongolera chapakati pa mizere yopanga yokhala ndi I/O yapakati komanso yogawidwa

PROFIBUS DP master/slave interface

Kuti muwonjezere I/O yonse

Pokonza kapangidwe ka I/O komwe kamagawidwa

Mawonekedwe osasinthika pa PROFIBUS

Khadi Lokumbukira la SIMATIC Micro lofunikira kuti CPU igwire ntchito.

Kugwiritsa ntchito

CPU 315-2 DP ndi CPU yokhala ndi pulogalamu yokumbukira yapakatikati mpaka yayikulu komanso mawonekedwe a PROFIBUS DP master/slave. Imagwiritsidwa ntchito m'mafakitale okhala ndi zomangamanga zogawika kuphatikiza I/O yapakati.

Nthawi zambiri imagwiritsidwa ntchito ngati PROFIBUS DP master mu SIMATIC S7-300. CPU ingagwiritsidwenso ntchito ngati nzeru zogawidwa (DP slave).

Chifukwa cha kuchuluka kwawo, ndi abwino kugwiritsa ntchito zida zaukadaulo za SIMATIC, mwachitsanzo:

Mapulogalamu ndi SCL

Kupanga mapulogalamu otsatirawa pogwiritsa ntchito S7-GRAPH

Kuphatikiza apo, CPU ndi nsanja yabwino kwambiri yogwirira ntchito zosavuta zaukadaulo zomwe zimayendetsedwa ndi mapulogalamu, mwachitsanzo:

Kuwongolera mayendedwe ndi Easy Motion Control

Kuthetsa ntchito zowongolera zotsekedwa pogwiritsa ntchito ma block a STEP 7 kapena pulogalamu yoyendetsera PID yokhazikika/yofanana

Kuzindikira bwino njira zodziwira matenda kungapezeke pogwiritsa ntchito SIMATIC S7-PDIAG.

Kapangidwe

CPU 315-2 DP ili ndi zinthu zotsatirazi:

Chosinthira chaching'ono;

Purosesa imapeza nthawi yokonza ya pafupifupi 50 ns pa malangizo a binary ndi 0.45 µs pa ntchito iliyonse yoyandama.

256 KB kukumbukira ntchito (kufanana ndi malangizo pafupifupi 85 K);

chikumbutso chachikulu cha ntchito cha magawo a pulogalamu okhudzana ndi kuchitidwa chimapereka malo okwanira kwa mapulogalamu ogwiritsa ntchito. Makhadi a SIMATIC Micro Memory (osapitirira 8 MB) monga chikumbutso cha katundu cha pulogalamuyi amalolanso pulojekitiyi kusungidwa mu CPU (yokhala ndi zizindikiro ndi ndemanga) ndipo ingagwiritsidwe ntchito posungira deta ndikuwongolera maphikidwe.

Kutha kukulitsa kosinthasintha;

Ma modules osapitirira 32 (makonzedwe a magawo anayi)

mawonekedwe a MPI a mfundo zambiri;

mawonekedwe olumikizidwa a MPI amatha kukhazikitsa maulumikizidwe okwana 16 nthawi imodzi ku S7-300/400 kapena maulumikizidwe ku zipangizo zamapulogalamu, ma PC, ma OP. Mwa maulumikizidwe awa, amodzi nthawi zonse amakhala a zipangizo zamapulogalamu ndipo ena a OP. MPI imapangitsa kuti zikhale zotheka kukhazikitsa netiweki yosavuta yokhala ndi ma CPU opitilira 16 kudzera mu "kulumikizana kwa data padziko lonse lapansi".

Mawonekedwe a PROFIBUS DP:

CPU 315-2 DP yokhala ndi mawonekedwe a PROFIBUS DP master/slave imalola kukhazikitsidwa kwa automation komwe kumapereka liwiro lapamwamba komanso kosavuta kugwiritsa ntchito. Malinga ndi momwe wogwiritsa ntchito amaonera, ma I/O ogawidwa amaonedwa chimodzimodzi ndi ma I/O apakati (makonzedwe ofanana, ma adilesi ndi mapulogalamu).

Muyezo wa PROFIBUS DP V1 umathandizidwa mokwanira. Izi zimawonjezera kuthekera kwa kuzindikira ndi kugawa kwa ma DP V1 standard slaves.

Ntchito

Chitetezo cha mawu achinsinsi;

Lingaliro la mawu achinsinsi limateteza pulogalamu ya wogwiritsa ntchito ku mwayi wosaloledwa.

Kubisa kwa block;

Ma function (FCs) ndi ma function blocks (FBs) amatha kusungidwa mu CPU mu mawonekedwe obisika pogwiritsa ntchito S7-Block Privacy kuti ateteze chidziwitso cha pulogalamuyo.

Chosungira matenda;

Zochitika zomaliza za 500 zolakwika ndi zosokoneza zimasungidwa mu buffer kuti zidziwike, zomwe 100 mwa izo zimasungidwa mosamala.

Kusunga deta popanda kukonza;

CPU imasunga deta yonse yokha (mpaka 128 KB) ngati magetsi alephera kugwira ntchito kotero kuti detayo ipezekenso yosasinthika magetsi akabwerera.
