The following control is possible using contact inputs (up to 8
points can be specified)
•
Memory start/stop (level)
•
Event data file using external trigger input (trigger, 250 ms
or more)
•
Time adjustment (adjust the time to on the hour using
contact input, trigger, 250 ms or more)
•
Computation start/stop (level)
•
Computed data reset (trigger, 250 ms or more)
•
Manual sample (trigger, 250 ms or more)
•
Message write operation (set up to 8 points, trigger, 250 ms
or more)
•
Load settings (up to 3 points, trigger, 250 ms or more)
•
Alarm ACK (trigger, 250 ms or more)
•
Snapshot (trigger, 250 ms or more)
FAIL/memory end output (/A4F option or /A4FR option)
Outputs relay contact signals when system errors occur, at the
specified time before overwriting of the internal memory is to
start, and based on the remaining free space on the external
storage medium.
Manual save mode:
Outputs relay contact signals the specified time before
overwriting starts (select from 1, 2, 5, 10, 20, 50, and 100 hours)
Auto save mode:
Outputs relay contact signals when the remaining free
space on the external storage medium falls to 10%.
Control DIO expansion (/CST1)
