14.5 Storage Function
External storage medium: Select from the following when ordering
• 3.5-inch floppy disk (2HD)
• PCMCIA ATA flash memory card (4 to 440 MB)
• Zip disk (100 MB or 250 MB)
Storage Function
Stores internal control loop data (PV/SP/OUT of internal loops), external control loop data
(PV/SP/OUT of externally connected controllers), measured data, and computed data
Internal control CH (PV/SP/OUT of each loop): 101 to 118 CH
External control CH (PV/SP/OUT of each loop): 201 to 248 CH
Stores 66 CH above, 20 measurement CH, and 30 computation CH as a data file
Storage data type:

Data save method: Manual save: Saves data when the external storage medium
is inserted
Auto save: Saves data through key operation during
continuous measurement
Save interval: 10 minutes to 31 days (during free trigger)
Saves at the end of sampling (when trigger is
specified)
Sampling Interval:
Display data file: Synchronized to the waveform
update rate
Event data file: Specify the sampling interval
Event data file sampling interval:Selectable from 1 and 2 s
Measurement data file:
Event data file: Saves the instantaneous values
at the specified sampling interval
Display data file: Saves the maximum and minimum
values within the display update rate
Combinations of files created
Event data file (trigger only) + display data file
Display data file only
Event data file only
Data format: Binary format
Data per channel:
Display data:
Control data:
4 bytes/data point
Measurement data: 4 bytes/data point
Computation data: 8 bytes/data point
Event data:
Control data:
2 bytes/data point
Measurement data: 2 bytes/data point
Computation data: 4 bytes/data point
