• PerformanceWhileDataIsBeingSaved
If the internal memory or external storage medium is continuously accessed, the
following phenomena may occur. When such phenomena occur, the storage medium
access indicator frequently illuminates.
• Filesbeingsavedtotheexternalstoragemediumdropout.
• AccessingtheDXthroughcommunicationstakesalongtime
In such case, take the following measures.
• Ifyouarecreatingdatafilesatshortintervalsconsecutivelyusingtheeventaction
function, increase the data file save interval.
• Ifyouarecreatingnumerousfilesinasingledirectoryontheexternalstorage
medium, change the destination directory name at approximately every 1000 files.
• Ifdatarecordinganddisplayareusingupresources(forexampleifyouare
recording on multiple channels using a fast sampling rate, and displaying four trend
displays on the 4-panel display), use a slower sampling rate or change the display.
