Excelov zapisovalnik podatkov XML iz sonikatorjev Hielscher v realnem času
Kako deluje
Ob zagonu skript uporabnika pozove, naj vnese izvorni naslov podatkov XML svojega sonikatorja (npr. http://192.168.233.233/mdata.xml). Nato ustvari strukturirano vrstico z naslovi stolpcev in začne pridobivati podatke vsako sekundo. Vsaka nova podatkovna točka se doda v tabelo, raztreseni grafikon s črtami pa prikazuje spreminjanje moči, amplitude in energije skozi čas. Vse vrednosti, ki označujejo napake senzorjev (npr. če senzor ni priključen), se samodejno izločijo.
Navodila za uporabnike sistema Windows
V Excelu odprite urejevalnik Visual Basic, vstavite nov modul in prilepite celoten skript. Po zagonu makra InitLogger se bo zapisovalnik samodejno zagnal. Poskrbite, da so makri omogočeni in da ima Excel dovoljenje za dostop do vašega omrežja.
Navodila za uporabnike sistema macOS
V Excelu odprite urejevalnik Visual Basic. Vstavite nov modul in prilepite celoten skript. Preprosto zaženite isti makro in podatki se bodo pridobivali prek navedenega naslova IP. Uporabniki sistema macOS morajo Excelu dovoliti izvajanje skriptov AppleScript in bodo morda morali v sistemskih nastavitvah odobriti dostop do omrežja, če bodo k temu pozvani.
Zaženite kodo VBA v Excelu, da naložite podatke XML iz sonikatorja v preglednico.
Posodobitve, izjava o omejitvi odgovornosti in licenca
Niz podatkov XML se lahko razlikuje glede na vrsto naprave in dobavljeno različico programske opreme. Vsebuje lahko drugačno število vrednosti, ki so lahko v drugačnem vrstnem redu ali obliki. Zato boste morda morali ustrezno prilagoditi spodnji skript. Ni nobenih obveznosti glede tehnične podpore, odpravljanja napak ali prihodnjih posodobitev. To orodje je na voljo brez kakršnih koli jamstev ali garancij. To izrecno izključuje implicitna jamstva, kot sta jamstvo za tržno primernost ali primernost za določen namen. Hielscher Ultrasonics ne odgovarja za nobeno škodo, vključno z neposredno, posredno ali posledično škodo, ki bi nastala zaradi uporabe programske opreme. To je zgolj primer. Brezplačna uporaba je dovoljena samo za nekomercialne in raziskovalne namene. Nadaljnje razširjanje je dovoljeno ob ustrezni navedbi avtorstva. Komercialna preprodaja ali vključitev v lastniške sisteme je brez predhodnega pisnega soglasja strogo prepovedana.

' 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.
