• 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 le 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 les,
increase the size of the les being saved.
• If you are saving multiple les to the same directory on an external storage
medium, change the name of the Save directory, making sure that the number of
les 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.
