SiIemens 6es7315-2ah14-0b0 sidic S7 300 CPU 315-2DP

Kulemeletsa

CPU yokhala ndi sing'anga yayikulu kukumbukira kukumbukira kwa pulogalamu ndi magulu ochulukirapo kuti mugwiritse ntchito zida zamagetsi

Mphamvu yayikulu mu binary ndikuyandama

Ntchito ngati wowongolera pakati pa mizere yopanga ndi pakati ndikugawika i / o

Phula ya DP / Akapolo

Pakuwonjezera

Pokonzekera kufalitsa i / o

Makina a Isochronous pa Phula

Khadi la Micro Meory Memory yofunika kugwira ntchito ya CPU.

Karata yanchito

CPU 315-2 DP ndi CPU yokhala ndi sing'anga yokhazikika ku Memory Memory ndi Profibus DP / Speciface mawonekedwe. Amagwiritsidwa ntchito muzomera zomwe zimakhala ndi zida zogawika zowonjezera kuwonjezera pa utoto wa i / o.

Nthawi zambiri imagwiritsidwa ntchito ngati mbuye wa Phiribulu wa DP mu Simic S7-300. CPU itha kugwiritsidwanso ntchito ngati anzeru (akapolo a DP).

Chifukwa cha kuchuluka kwawo, ndi abwino kugwiritsa ntchito zida zojambula bwino, mwachitsanzo:

Mapulogalamu ndi scl

Mapulogalamu ogwiritsa ntchito njira ndi s7-graph

Kuphatikiza apo, CPU ndi nsanja yabwino yothandizira ukadaulo wosavuta wa mapulogalamu, mwachitsanzo:

Kuwongolera koyenda ndi kuwongolera kosavuta

Kuthetsa ntchito zotsekera zoyendetsedwa ndi mabatani 7 kapena muyezo / molangula pick

Kuzindikira kowonjezera kumatha kuchitika pogwiritsa ntchito Simisala S7-PDIG.

Jambula

CPU 315-2 DP yokhala ndi izi:

Microcrosent;

Pulogalamuyo imakwaniritsa nthawi yosintha pafupifupi 50 ns iliyonse yolangizidwa ndi 0,45 μ pa ntchito yoyandama.

Memory 256 KB Kugwira (kumafanana ndi pafupifupi. 85 K malangizo);

Kukumbukira kwakukulu kwa mapulogalamu a mapulogalamu okhudzana ndi kuphedwa kokwanira kuphedwa kokwanira mapulogalamu ogwiritsa ntchito. Makhadi a Micro Meory Memory (8 MB Max.) Monga Lolani Log Log Log kuti pulogalamuyi isungidwe mu CPU (yokwanira ndi zizindikiro) ndipo imatha kugwiritsidwa ntchito poyendetsa deta.

Kuthekera kosinthasintha;

Max. 32 ma module (makonzedwe anayi)

Mawonekedwe angapo a MPI;

Mawonekedwe ophatikizidwa a MPI amatha kukhazikitsidwa mokwanira 16 nthawi yomweyo mpaka s7-5-300 / 400 kapena malumikizidwe ndi zida zama pulogalamu, ma PC, Ops. Mwa zolumikizira izi, imodzi imasungidwa zida zamagetsi ndi ina kwa ops. MPI imapangitsa kukhazikitsa netiweki yosavuta yokhala ndi 16 CPU kudzera pakulankhulana kwa data yapadziko lonse lapansi ".

Phula la DP PLP:

CPU 315-2 DP ndi Phulasi ya DP Kuchokera pakuwona kwa wogwiritsa ntchito, omwe amagawidwa i / OS amachitidwanso chimodzimodzi ndi pakati.

Ma profibus PP v1 muyezo umathandizidwa kwathunthu. Izi zimawonjezera kuzindikira ndi kuthekera kwa ntchito ya DP v1 muyezo.

Kugwira nchito

Chitetezo chachinsinsi;

Malingaliro achinsinsi amateteza pulogalamu yosuta kuchokera posaloledwa.

Block Scrryption;

Ntchito (fcs) ndi ntchito zopangira (fbs) zitha kusungidwa mu CPU mu mawonekedwe a scryted pogwiritsa ntchito chinsinsi cha S7-block kuti muteteze zomwe mukudziwa.

Matenda osokoneza bongo;

Zolakwika 500 zomaliza komanso zochitika zosokoneza zimasungidwa mu buffer kuti ziwonekere, zomwe zimasungidwa 100 zomwe zimasungidwa.

Kusunga deta yosungirako deta;

CPU yokha imasungira zonse (mpaka 128 kb) ngati vuto lamphamvu kuti detaliyo ipezekanso osasinthika pomwe mphamvu ibwerera.
