Bayanin Aiki:
UCSCH1A mai kula da quad-core ne wanda ke amfani da fasahar hypervisor na ainihin lokaci don daidaitawa da rarraba albarkatun kayan aikin jiki (CPU, ƙwaƙwalwar ajiya, mu'amalar cibiyar sadarwa), ta haka ƙirƙirar keɓaɓɓen mahallin injin kama-da-wane. Kowane VM na iya gudanar da tsarin aiki mai zaman kansa da aikace-aikace, kamar yana gudana akan kwamfutoci daban-daban.

Ka'idar Aiki:

• Layer Abstraction Hardware: Hypervisor, a matsayin software mafi ƙanƙanta, yana gudana kai tsaye akan kayan masarufi mai sarrafawa kuma yana da alhakin tsara tsarin abubuwan CPU, rarraba ƙwaƙwalwar ajiya, da sarrafa katsewar kayan aiki. Yana ba da daidaito, ingantaccen ra'ayi na kayan aikin zuwa VMs na sama-Layer.

• Warewa Injin Kaya: A kan UCSCH1A, daidaitaccen tsari yana gudanar da VM masu zuwa:

• Mark VIe Control VM: Yana gudanar da QNX Neutrino RTOS, ingantaccen tsarin aiki na ainihin lokacin abin dogaro. QNX yana da alhakin aiwatar da duk mahimman dabarun sarrafa tsari. Tsarin gine-ginen microkernel da tsara jadawalin aiki yana tabbatar da cewa an kammala ayyukan sarrafawa a cikin ƙayyadaddun tsarin zagayowar lokaci, tare da biyan matsananciyar buƙatun sarrafa masana'antu.

• Embedded PROFINET Gateway VM: Yana gudanar da wani yanayin tsarin aiki wanda aka inganta musamman don tarin ka'idojin PROFINET, sadaukar don sarrafa sadarwa tare da hanyar sadarwar PROFINET.

• Wakilin Filin Embedded VM: Yana gudanar da tsarin Linux don karɓar aikace-aikacen EFA.

A matsayin mai sarrafa Mark VIe, UCSCH1A yana sadarwa tare da nau'ikan I / O da aka rarraba ta hanyar IONet, sadaukarwa, cibiyar sadarwa ta Ethernet masana'antu mai ƙima, don cim ma sayan bayanan tsari da fitar da umarnin sarrafawa.

Ka'idar Aiki:

• Sadaukarwa Network: IONet rufaffiyar ce, cibiyar sadarwa mai zaman kanta wacce kawai ke ba da damar GE's Mark series I/O modules da masu sarrafawa don haɗawa. Wannan rufaffiyar yanayin yana hana samun izini mara izini da watsa guguwa daga cibiyoyin sadarwa na IT ko na'urorin waje, yana tabbatar da tsabta da tsaro na cibiyar sadarwa.

• Daidaitaccen Agogon Aiki tare: IONet yana amfani da IEEE 1588 Protocol Precision Time Protocol (PTP). Mai sarrafawa yana aiki azaman agogo mai girma, lokaci-lokaci yana aika saƙonnin aiki tare akan hanyar sadarwa don aiki tare da agogon duk na'urorin I/O da aka haɗa tare da kanta, tare da kuskuren sarrafawa tsakanin ± 100 micro seconds. Wannan babban matakin daidaiton lokaci shine tushe don:

• Samun Bayanai na Daidaitawa: Duk nau'ikan I/O suna iya 'hoton hoto' na siginar shigarwa a lokaci guda, suna samar da tsarin sarrafawa tare da daidaiton bayanai na duniya cikin lokaci, wanda ke da mahimmanci don nazarin hadaddun abubuwan da suka haɗa kai.

• Manufofin Sarrafa Ƙaddara: Zagayowar sikanin mai sarrafawa da zagayowar sabunta bayanai na I/O duk suna cikin layi tare da wannan agogon da aka haɗa aiki tare, yana tabbatar da ƙayyadaddun lokaci don sarrafa aiwatar da dabaru da musayar bayanai, yana kawar da rashin tabbas da ke haifar da jitter lokaci a cikin tsarin asynchronous na gargajiya.

• Hanyoyi masu yawa na Bayanai: A cikin saitunan da aka sake maimaitawa (Dual ko TMR), duk hanyoyin sadarwar I/O (R, S, T) ana haɗa su lokaci guda zuwa kowane mai sarrafawa. Wannan yana nufin kowane mai sarrafawa yana karɓar duk bayanan shigar da kansa. Wannan gine-ginen yana tabbatar da cewa babu bayanan shigar da aka rasa lokacin da aka yi amfani da mai sarrafawa guda ɗaya don kiyayewa ko ya gaza, ba tare da cimma wata maƙasudi ɗaya na asarar shigarwa ba da kuma tabbatar da ci gaba da sarrafawa a matakin sadarwa.

3. Ƙofar PROFINET mai ciki

Bayanin Aiki:
Wannan sigar sa hannu ce ta UCSCH1A. Yana iya aiki azaman PROFINET IO-RT V2.2 Class AI/O Controller ba tare da buƙatar kayan aikin ƙofar waje ba, haɗa kai tsaye da sarrafa na'urorin I/O na ɓangare na uku waɗanda ke goyan bayan ka'idar PROFINET (kamar RSTI-EP Slice I/O).

Bayan injiniyoyi masu sarrafawa sun daidaita wannan alaƙar taswira a cikin software na ToolboxST, za su iya yin la'akari da waɗannan bayanan PROFINET kai tsaye a cikin dabarun sarrafawa kamar masu canjin I/O na asali.

• Gudun Bayanai Asynchronous: Zagayowar sabunta bayanai na cibiyar sadarwar PROFINET yayi daidai da zagayowar sikanin mai sarrafa Mark VIe. PPNG VM da kanta tana yin musayar bayanai ta keke-da-keke tare da na'urorin PROFINET a ƙimar haɓakawa mai daidaitawa (1ms zuwa 512ms). Sannan yana batches sabbin bayanai zuwa Mark VIe iko VM ta hanyar hanyar sadarwa ta ciki da aka ambata. Wannan ƙirar asynchronous tana hana na'urorin PROFINET a hankali daga jinkirin madaukai masu mahimmanci.

• Kafa Dangantakar Sadarwa: Kafin a fara sadarwa, PPNG ta kafa dangantakar Sadarwa (CRs) iri uku tare da kowace na'urar PROFINET:

• Yi rikodin bayanan CRs: Ana amfani da shi don canja wurin bayanai mara-lokaci, kamar daidaita ma'aunin na'ura da karanta bayanan bincike.

• IO Data CRs: Ana amfani da shi don ainihin-lokaci, musayar cyclic na bayanan tsari (shigarwa / fitarwa), wanda shine ainihin aikin sarrafawa.

• Bayanan Ƙararrawa CRs: Ana amfani da shi don watsa ƙararrawa na ainihi da bayanin taron daga na'urar.

• Rabewar hanyar sadarwa: Farawa daga ControlST V07.04, UCSCH1A tana goyan bayan rabuwa ta jiki na cibiyoyin sadarwar IONet da PROFINET. PPNG VM yana sadarwa tare da Mark VIe iko VM ta hanyar sauyawa na IONet na ciki, yayin da a waje yana amfani da tashar tashar ENET2 da aka keɓe don haɗi zuwa cibiyar sadarwar PROFINET. Wannan rabuwa yana haɓaka tsaro na cibiyar sadarwa da sarrafawa.

4. Wakilin Filin Ciki

Bayanin Aiki:
EFA ita ce gadar da ke haɗa gefen masana'antu zuwa dandalin girgije na Predix. Yana gudana a cikin Linux VM akan UCSCH1A, wanda ke da alhakin tattara bayanan na'ura amintacce da watsa shi zuwa gajimare, yayin da kuma yake aiki azaman dandamali na lissafin gefe don aikace-aikacen tushen girgije na cikin gida.

5. Ragewa da Ka'idodin Samar da Babban Samfura

Bayanin Aiki:
UCSCH1A yana goyan bayan saitunan Simplex, Dual, da TMR don saduwa da ƙaƙƙarfan buƙatun samuwa na aikace-aikace daban-daban.

Ka'idar Aiki:

• Kanfigareshan Biyu:

• Masu kula da UCSCH1A guda biyu suna gudana a layi daya, a lokaci guda suna aiwatar da aikace-aikacen sarrafawa iri ɗaya da sarrafa bayanan shigarwa iri ɗaya.
