Recording Method of Display Data and Event Data
For the setting procedure, see section 6.1.
• Types of Data to Be Acquired
Select display data only, display data and event data, or event data only.
Deciding the Data to Be Recorded
Record the data that suits your application. Refer to the following examples.
Example 1: Continuously record the waveform data as with the conventional chart
recorder.
Record the display data.
Example 2: Record waveform data under normal conditions but record details around
the point of alarm occurrence when alarms occur.
Continuously record display data and record event data when alarms
occur
.
Example 3: Only record the most-detailed data at all times.
Record event data by specifying the sampling interval.
Example 4: No need to continuously record data. Record data only when alarms
occur.
Record event data only when alarms occur.
• Internal Memory
The recorded measured data is divided at a specific time interval and saved to files.
If the internal memory is full or if the number of display data files and event data files
exceeds 400, files are overwritten from the oldest file.
• Recording Conditions of Display Data
Item Description
Source channels Select from measurement channels, computation channels, and
external input channels.
Sampling interval Specify the sampling interval with the trend interval (see the table
below). You cannot specify a sampling interval that is faster than the
scan interval.
File creation Files are created at the specified file save interval
Time
File File File Adding data
Files are also created in the following cases.
•
When a file is created manually.
•
When the memory sampling is stopped.
•
When file creation is executed with the event action function.
•
After recovering from a power failure.
Memory start/stop Press the START key to start recording (memory start) and the
STOP key to stop the recording (memory stop).
