FX4 Polokalama Ua Umaview
O le FX4 processor e tamoʻe i luga o se siʻosiʻomaga e taʻua o le IGX, lea e fausia i luga o le QNX maualuga-faʻatuatuaina faiga faʻaoga taimi moni mai BlackBerry (QNX Webnofoaga¹). O le IGX e tuʻuina atu se faʻaoga fetuutuunai ma faʻamalamalamaga polokalame faʻaoga (API) mo tagata faʻaoga e manaʻo e tusi a latou lava polokalama komepiuta talimalo.
O le siosiomaga IGX o loʻo faʻasoa i isi oloa Pyramid, faʻatagaina fofo faʻapipiʻi e atiaʻe mo se tasi oloa e faigofie ona faʻafeiloaʻi i isi.
E mafai e le au fai polokalame ona va'ai i fa'amaumauga atoa mo le IGX o lo'o maua ile Pyramid webnofoaga i: IGX | Fa'aonaponei Modular Control System Framework mo Web-e mafaia Talosaga²
O lenei vaega o loʻo tuʻuina atu ai se folasaga i le suʻeina o auala API e lua: HTTP faʻaoga JSON format ma EPICS. Mo le faigofie, Python (Python Webnofoaga³) o loʻo faʻaaogaina e fai ma faʻataʻitaʻigaample gagana komepiuta talimalo, lea e mafai ona maua ma faigofie ona faʻaoga mo tagata fai polokalame e le faʻapitoa.
3.1 Faʻaaogaina o le Python ma le HTTP
I le avea ai ma se example, fa'apea e te mana'o e faitau le aofa'i o fua fa'atatau ma le Python. E te mana'omia le URL mo lena IO faapitoa. O le FX4 web E maua e le GUI se auala faigofie e maua ai lenei mea: naʻo le kiliki-saʻo i le fanua ma filifili 'Kopi HTTP URL'ia kopi le manoa i le laupapa kilipa.
Ole taimi nei e mafai ona e faʻaogaina le Python e faʻataʻitaʻi ai le fesoʻotaʻiga i polokalama faʻaoga e ala ile HTTP ma JSON. Atonu e te manaʻomia le faʻaulufaleina mai o talosaga ma faletusi json e faʻatautaia ai talosaga HTTP ma faʻamaumauga faʻamaumauga.

3.2 Fa'aaogaina EPICS
Ole fa'agasologa ole feso'ota'iga ole FX4 ile EPICS (Experimental Physics and Industrial Control System) e tutusa. EPICS o se seti o meafaigaluega faakomepiuta ma talosaga e faʻaaogaina e atiaʻe ma faʻatino faiga faʻatonutonu tufatufaina, faʻaaogaina lautele i nofoaga faʻasaienisi.
- Maua le igoa EPICS process variable (PV) mo le IO mana'omia.
- Auina mai le faletusi EPICS ma faitau le tau.

FX4 Python Examples
5.1 Fa'amaumauga Logger fa'aaoga HTTP
O lenei exampLe fa'aalia pe fa'afefea ona pu'eina se numera o faitauga ma fa'asaoina i se CSV file. E ala i le filifilia o se faʻatuai umi i le va o faitauga, e mafai ona e faia faʻamaumauga faʻamaumauga umi e tusa lava pe o le FX4 sampling rate ua seti maualuga. Ole mea lea e fa'atagaina ai oe e fa'aauau le aoina ma teu fua i taimi uumi e aunoa ma le fa'apopoleina o le faiga, fa'amautinoa o lo'o pu'eina fa'amaumauga i taimi e talafeagai mo au su'esu'ega. O le tuai i le va o faitauga e fesoasoani e faʻatonutonu le saoasaoa o loʻo faʻamauina ai faʻamaumauga, faʻatagaina mo le teuina lelei ma faʻaitiitia le lamatiaga o le misi o faʻamaumauga aʻo faʻamanuiaina mai le saoasaoa maualuga s.ampling mo fua taimi moni.
5.2 GUI Python faigofie
O le ex lona luaampLe faʻaaogaina le meafaigaluega GUI Tkinter, lea ua fausia mo Python, e fai ai se faʻaaliga o le fuaina o galu. O lenei fa'aoga e mafai ai ona e va'ava'ai i faitauga o lo'o i ai nei i se fa'ata'ita'iga fa'akomepiuta fa'aoga. E mafai ona sui le fa'aaliga ina ia lava lona lapoa e faitau mai ai i le isi itu o se potu, ma fa'alelei ai mo fa'aaliga e mana'omia ai le mata'ituina o taimi moni i avanoa tetele. E saunia e Tkinter se auala faigofie e fatuina ai fesoʻotaʻiga fefaʻasoaʻi, ma e ala i le tuʻufaʻatasia ma le FX4, e mafai ona e vave fausia se faʻaaliga vaaia o le fuaina o galu e mafai ona faʻatulagaina e fetaui ma ou manaʻoga patino.
5.3 Faigofie WebSockets Example
O lenei example fa'aalia le WebSockets interface, o le auala sili lea mo le faitauina o faʻamatalaga mai le FX4 pe a manaʻomia le bandwidth maualuga. WebSockets e maua ai se taimi moni, fesoʻotaʻiga atoa-duplex, faʻatagaina mo le televave ma sili atu ona lelei le faʻaliliuina o faʻamatalaga pe a faʻatusatusa i isi metotia.
O le example faitau se faasologa o samples, lipoti le averesi taimi i le sample ma le maualuga o le latency, ma fa'asaoina fa'amaumauga i se CSV file mo su'esu'ega mulimuli ane. O lenei seti e mafai ai mo le mataʻituina lelei o taimi moni ma faigofie le teuina o faʻamaumauga mo le faʻagasologa o faʻasologa.
Le faʻatinoga faʻapitoa e mafai ona ausia ma WebSockets e fa'alagolago i le fa'atuatuaina o lau feso'ota'iga Ethernet ma le fa'amuamua o lau talosaga. Mo fa'ai'uga lelei, fa'amautinoa o lo'o mautu lau feso'otaiga ma fa'amuamua le fa'asalalauina o fa'amaumauga a le FX4 pe a mana'omia.
