Zapisivač XML podataka Hielscher sonikatora u Excelu u stvarnom vremenu
Kako radi
Pri pokretanju skripta traži od korisnika da unese izvornu adresu XML podataka svojeg sonikatora (npr. http://192.168.233.233/mdata.xml). Zatim stvara strukturirani redak zaglavlja i počinje dohvaćati podatke svake sekunde. Svaka nova podatkovna točka dodaje se u tablicu, a raspršeni grafikon s linijama prikazuje promjene snage, amplitude i energije tijekom vremena. Sve vrijednosti koje označavaju pogrešku senzora (npr. ako senzor nije priključen) automatski se filtriraju.
Upute za korisnike sustava Windows
Otvorite uređivač Visual Basic u Excelu, umetnite novi modul i zalijepite cijelu skriptu. Nakon pokretanja makronaredbe InitLogger zapisivač će se automatski pokrenuti. Provjerite jesu li makronaredbe omogućene i ima li Excel dopuštenje za pristup vašoj mreži.
Upute za korisnike sustava macOS
Otvorite uređivač Visual Basic u Excelu. Umetnite novi modul i zalijepite cijelu skriptu. Jednostavno pokrenite istu makronaredbu i podaci će se dohvaćati putem navedene IP adrese. Korisnici sustava macOS moraju dopustiti Excelu pokretanje AppleScripta, a ako se to od njih zatraži, možda će morati odobriti pristup mreži u postavkama sustava.
Pokrenite VBA kod u Excelu za učitavanje XML podataka sonikatora u proračunsku tablicu.
Ažuriranja, odricanje od odgovornosti i licencija
Ovisno o vrsti uređaja i isporučenoj verziji softvera, niz XML podataka može se razlikovati. Može sadržavati drukčiji broj vrijednosti, koje mogu biti u drukčijem redoslijedu ili formatu. Stoga ćete možda morati odgovarajuće prilagoditi skriptu u nastavku. Ne postoji obveza pružanja tehničke podrške, ispravljanja programskih pogrešaka ni budućih ažuriranja. Ovaj se alat pruža bez ikakvih garancija ili jamstava bilo koje vrste. Time se izričito isključuju podrazumijevana jamstva poput utrživosti ili prikladnosti za određenu svrhu. Hielscher Ultrasonics ne odgovara ni za kakvu štetu, uključujući izravnu, neizravnu ili posljedičnu štetu, koja proizlazi iz uporabe softvera. Ovo je samo primjer.

' Realtime Excel Logger for Hielscher Sonicator XML Data
'
' Description:
' This VBA module fetches XML data from a Hielscher sonicator over the network
' (typically from a local IP like http://192.168.233.233/mdata.xml), parses it,
' logs real-time data into Excel, and visualizes selected parameters (Power, Amplitude,
' and Energy) using a live updating scatter-line chart.
