• Saving the Data in the Internal Memory Collectively or Selectively
through Key Operation
See section 4.8.
Explanation
• Operations That Start Simultaneously with Memory Start
• Waveform display updating on the trend display.
• Report (/M1 and /PM1 options)
• The computation function (/M1 and /PM1 options) can be configured to start
simultaneously with memory start.
See section 9.4.
• Operations That Stop Simultaneously with Memory Stop
• Waveform display updating on the trend display.
• Report (/M1 and /PM1 options)
• Computation function (/M1 and /PM1 options): When selected in the procedure
described above.
• 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.
