• Save Problems
The following problems may arise when the MV is continually accessing internal or
external memory. If these problems arise, the storage media access indicator will light
frequently.
• External storage media file save error
• Access timeout
These problems can be dealt with in the following ways.
• If you are using the event action function and saving small consecutive files,
increase the size of the files being saved.
• If you are saving multiple files to the same directory on an external storage
medium, change the name of the Save directory, making sure that the number of
files in the directory does not exceed 1000.
• 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.
