Varioussoftwarefunctionsretrievedatafromthedatacacheinsteadof
theCR800directly.Thisallowsthesimultaneoussharingofdataamong
softwarefunct
ions.
SimilarinfunctiontoCR800finalstoragetables,thebinaryfilefora
dataloggerissetupasringmemory.Thismeansthatasthefilereaches
itsmaximumsize,thenewestdatawillbeginoverwritingtheoldest
data.
