• Block display
When the event data acquisition area is divided into multiple blocks, the block
usage is displayed.
White blocks: Blocks with no data.
Green blocks: Block containing data that was acquired to the internal
memory after starting the current acquisition of event data.
Gray blocks: Blocks containing previous data.
7. Icon indicating the external storage medium status
If F and G are displayed alternately, the external storage medium is being
accessed. If the icon is not displayed, this indicates that an external storage
medium is not inserted in the drive. Other indications are as follows.
E: The operation cover on the front panel is open.
G: External storage medium waiting (not being accessed).
H: The green level inside the icon indicates the amount of the external storage medium
used. If the remaining amount falls to 10% or less, the color changes to red.
Note
• The CX2000 detects whether an external storage medium is inserted in the drive when the
operation cover is closed.
• To prevent adverse effects from dust, use the CX2000 with the door closed.
8. Computation icon (only on models with the computation option)
No computation mark is displayed: No computation option or computation is stopped.
White computation icon:
Computation in progress.
Yellow computation icon: Computation dropout occurred.
Note
Computation dropout occurs when the computation process cannot be completed within the
scan interval. Press “FUNC > [Math ACK] soft key” to set the icon back to a white
computation icon. If computation dropouts occur, increase the scan interval or reduce the
number of computation channels that are turned on.
9. Key lock icon
Key icon: Key locked
No indication: No key lock
10. E-mail transmission function icon
Displayed when the e-mail transmission function (see the DAQSTATION CX1000/
CX2000 Communication Interface User’s Manual
) is enabled.
11. Alarm icon
Displayed when any one of the alarms is occurring.
• Data Display Section
The control operation display shows the PV input values, SPs, and OUT for
