Produktforbedring spesielt knyttet til «eldre» DEIF A/S ML-2 produkter

På grunn av den høye kvaliteten, og dermed lange levetiden på DEIF produkter, har det totale antall «eldre» DEIF enheter i feltet økt gjennom årene. Gjennom DEIFs kontinuerlige fokus på produktkvalitet, produktytelse og tilbakemeldinger fra kunder – Også for de «gamle» produktene våre – Har vi funnet en mulig forbedring spesielt knyttet til kontrollenhetene våre: AGC-2, AGC-3, AGC-4, BGC-2 og MDR-2.

Den oppdaterte programvaren vil aktivere enheten for å utføre en «intern selvtest» ved å overvåke «helsetilstanden» til ulike hardware/software funksjoner. Interne problemer som oppdages vil utløse en alarm, basert på hvilke DEIF serviceavdeling som skal kontaktes.

I tillegg utvikler DEIF for tiden et verktøy til å håndtere konfigurasjonsfiler, noe som vil gjøre deg i stand til å enkelt kunne laste opp og lagre filer for senere re-konfigurasjon av enheter etter service, utilsiktede operatørendringer etc. Verktøyet vil gjøres tilgjengelig senere.

Som alltid, anbefaler vi at du installerer forbedringene våre for å kunne utnytte DEIF produktet ditt fullt ut.

All forbedret programvare kan gratis lastes ned på nytt på under «Programvare» og deretter « Programvarenedlasting».

Skulle du ha noen spørsmål eller om du skulle oppleve problemer med å finne relevant programvare til produktet ditt, kan du gjerne ringe DEIF A/S på +45 96149614 eller ditt relevante lokale DEIF kontor. Ellers er vi alltid klare til å hjelpe deg dersom du sender en e-post til
