IC697CPM790 GE Fanuc 80486DX2 Na’urar Sarrafawa Aikin TMR

Takaitaccen Bayanin Samfur

GE Fanuc IC697CPM790 babbar ƙwayar sarrafa tsakiyar aiki ce (central processing module) a cikin dangin Series 90-70, wadda aka ƙera don tsarin kula da masana’antu masu buƙatar samun aiki ba tare da yankewa ba. Yana da ƙwarewar tallafawa Triple Modular Redundancy (TMR), wanda ke ba da kariyar kuskuren tsarin har zuwa kashi 99.9% ga muhimman kayayyakin more rayuwa. Wannan mai kula yana amfani da ƙarfi 64 MHz 80486DX2 microprocessor don sarrafa lissafi mai rikitarwa da tattara bayanai cikin sauri. Yana mamaye rami ɗaya kawai na shigarwa, don haka yana ba da mafita mai ƙanƙanta amma mai ƙarfi ga manyan tsarin sarrafa kansa (automation) na masana’antu.

Ingancin aiki babban siffa ce ta IC697CPM790, inda yake da saurin aiwatar da boolean na microseconds 0.4 a kowane aikin. Tare da iyawar sarrafa bayanai na 256 KB, yana sarrafa manyan tsarin I/O da shirye‑shiryen mai amfani masu rikitarwa cikin sauƙi. An haɗa fitilu huɗu na LED domin samun ganewar matsalar CPU da kallo kawai, da kuma tashoshi biyu na serial da aka haɗa a ciki don sadarwa ba tare da tangarda ba da na’urorin shirye‑shiryen ko wasu na’urorin gefe. Yana aiki da daidaitaccen shigar wutar 24V DC tare da juriya na ± 20%, wanda ke tabbatar da kwanciyar hankali a yanayin canje‑canjen wuta.

Siffofin Jiki & Nauyi

An tsara shi ne don manyan kabad na masana’antu masu cunkoso, IC697CPM790 yana da siffar jiki mai sauƙin sakawa tare da girman 21 cm x 23 cm x 5 cm. Wannan module ɗin yana da sauƙin nauyi a cikin ajinsa, domin yana nauyin kawai 0.6 kg (kimanin 1.32 lbs), wanda ke rage matsin nauyi da ake yi wa backplane a lokacin girgizar jiki. Gininsa mai ƙarfi yana ba shi damar aiki a faɗaɗɗen zangon zafin aiki daga -20°C zuwa 60°C, don haka ya dace da muhallin masana’antu da ba su da cikakken sanyaya ko dumama.

Redundancy & Dogaro

Babban fa’ida ta IC697CPM790 ita ce goyon baya na TMR da aka gina a cikinsa. A wannan tsarin, CPUs uku da aka daidaita suna sarrafa bayanai ɗaya a lokaci guda, suna amfani da tsarin “zabe” domin tabbatar da cewa gazawar sashi guda ba zai rusa dukan tsarin ba. Wannan redundancy na kayan aiki, tare da kashi 99.9% na juriya ga gazawar tsarin, yana sanya shi zaɓi da ake fi so ga safety‑instrumented systems (SIS) da manyan tsare-tsaren sarrafa ci gaba inda tsayawar aiki (downtime) ke da tsadar tattalin arziki sosai.

Tambayoyi da Amsoshin Fasaha

Q1: Menene amfanin processor ɗin 80486DX2 a cikin wannan module ɗin?
A1: 64 MHz 80486DX2 yana ba da ƙarin ƙarfi sosai a lissafin floating‑point da aiwatar da umarni masu rikitarwa idan aka kwatanta da CPUs na baya na Series 90-70, wanda hakan ke ba da damar saurin scan mafi girma ga manyan shirye‑shiryen PLC.

Q2: Nawa ne tashoshin serial da ake da su don haɗa na’urorin gefe?
A2: Wannan module ɗin yana da tashoshi biyu na serial da aka haɗa a ciki, galibi ana amfani da su don sadarwar SNP/SNP-X master/slave, shirye‑shiryen na’ura, ko haɗawa da na’urorin HMI.

Q3: Shin IC697CPM790 na buƙatar takamaiman wutar lantarki?
A3: Yana aiki ne a cikin zangon ƙarfin wuta na 24V DC ± 20% kuma yana dacewa da daidaitattun modules na wutar lantarki da ake sakawa a rack na Series 90-70.
