CF Card Informaton
You can check the status, maximum size, and free area of the CF card inserted into
the MX100. To check this information, click the CF Information button of the unit in the
Configuration area.
Click here.
Note
If communications fail when downloading the CF information, a dialog box appears with the
message, “Failed to acquire CF information. Check the host name and instrument status.”
Settng the Wrte Mode of the CF Card
If you wish to save new data files by deleting old files when there is no more free space
on the CF card, select the Use CF Card Cyclically check box in the Configuration area.
To stop the save operation when there is no more free space, clear the check box.
Click here.
Explanaton
Unt Number
The unit number is assigned in the displayed order in the Configuration area of the
System screen from 0 to 19. The unit number is the highest two digits of the five-digit
channel number. For example, if the unit number is 2, the channel number is 02XXX
(where XXX is the channel number in the unit).
Measurement Group
The system is capable of monitoring the data using three different measurement
intervals. Therefore, each input module is assigned to any of the three measurement
groups. You can set the measurement interval (Mon. Interval on the screen) of each
measurement group on the Acquisition setup screen (see the next section).
Settng the A/D Integraton Tme of the Unversal Input Modules
Settings are possible under the following conditions.
• When the measurement interval of the 4-CH, High-Speed Universal Input Module is 50 ms
• When the measurement interval of the 10-CH, Medium-Speed Universal Input Module
is 500 ms
• When the measurement interval of the 30CH, Medium-Speed DCV/TC/DI Input
Module is 1s.
• When the measurement interval of the 6-CH, Medium-Speed 4 Wire RTD Resistance
Input Module is 500 ms
• When the measurement interval of the 4-CH, Medium-Speed Strain Input Module is 200 ms
In these cases, you can select from the following. The default setting is AUTO.
• AUTO: Automatically sets the corresponding A/D integration time for 50 Hz or 60 Hz
according to the frequency of the power supplied to the main module.
• 50 Hz: Sets the integration time to 20 ms.
• 60 Hz: Sets the integration time to 16.67 ms.
Settng the Wrte Mode of the CF Card
If a CF card is inserted and the connection to the MX100 is cut off while the measured/
computed is being recorded, the measured data is saved (backed up) to the CF card.
If the Use CF Card Cyclically check box is selected and measured data is saved in
backup mode, the data continues to be saved by deleting the oldest data file when there
is no more free space on the CF card. If the check box is cleared, the data save operation
stops when there is no more free space on the CF card. This setting applies to all units.
