8.1 Data Types to be Acquired and Saved
Data Types and File Names
Data type
The types and the contents of the data that are acquired are as follows. Beside those
data listed below, the setup data (see section 9.1) and the screen image data (see
section 9.6) can be saved to the external storage medium.
Type Content
Display data • Waveform data that are used to display trends on the LCD screen.
• The maximum and minimum values from measured/computed data
within the sampling intervals are held.
• A header string can be written into the display data file (a character
string that is common to all data files).
• Alarm and message information is held.
• Data format : Binary format
Event data • The instantaneous values of the measured/computed data are
acquired at the specified sampling interval. There is a mode in which
the data acquisition is started when a trigger occurs or another mode
in which the data acquisition is started when the START key is
pressed.
• The header string can be written into the event data file (a character
string that is common to all data files).
• Alarm and message is held.
• Data format : Binary format
Manual sampled data • Every time a key that executes manual sampling is pressed,
measured/computed data (instantaneous values) of all channels at
that point are acquired.
• Up to 50 samples of data can be stored in the internal memory.
• The header string can be written into the manual sampled data file (a
character string that is common to all data files).
• Data format : ASCII format
TLOG data (option) • TLOG data are statistical computation data.
• Data are added to the internal memory at the end of every interval
period.
• Up to 400 data sets can be stored in the internal memory.
• The header string can be written into the TLOG data file (a character
string that is common to all data files).
• Data format : Binary format
Report data (option) • Consists of hourly, daily, weekly, and monthly reports. Data are
computed at intervals depending on the report type (one hour for
hourly report, one day for daily report, etc). Data are added to the
internal memory at the end of every interval period.
• Up to 40 reports can be stored in the internal memory.
• Each report file can contain up to 12 measured/computed channels
of report data.
• The header string can be written into the report data file (a character
string that is common to all data files).
• Data format : ASCII format
