5. The dialog box entries include:
Interval Trigger
Uses the interval timer (interval 1 timer) to set the scan
rate for normal operation in a module. The interval is user
settable.
External Trigger
Uses the Trigger input signal to start a scan. Each time
the external trigger is activated, another scan is taken.
Alarm Trigger (NetDAQ and 2680A Series modules)
Uses a second-interval timer (interval 2 timer) to start to
scan when an alarm condition is encountered by the
module. There is an interval timer (interval 3 timer) used
to look for alarms. The default for that timer is 0.1 s for
the FAI and 1 s for the PAI.
Drift Correction (2680A and NetDAQ only)
Automatically selected when the reading rate is set to
Slow (High Res.). The check box can also be clicked to
clear the check box. Drift correction is used primarily to
compensate for temperature drift. Clearing the check box
lets readings be taken more quickly.
Reading Rate / Sample rate
Select the slow reading rate for high precision or the fast
reading rate for high speed. Actual reading rate depends
on the function selected.
Conditional Scan Storage (2680A Series modules )
Used to specify when to store scan data. Always is the
default selection. On Alarm stores scan data as long as
the alarm condition exists. On Alarm Transition stores
scan data only when the alarm first occurs. On Alarm
stores the least amount of data.
On Line CSV file creation
Moves scan data directly to a CSV-compatible file instead
of storing it first in a binary format.
Note
If configuring a DIO module, NetDAQ, 2638A, or
1586A, the Totalizer Configuration dialog is
shown as in the screen below.
