Period Trigger (Enhanced)
The DL850E/DL850EV triggers on a specified period of occurrence of state condition B. The DL850E/DL850EV
triggers when state condition B occurs again.

Trigger Source
You can use CH1 to CH16 and Bit 1 to Bit 8 as the trigger sources. Bit 1 to Bit 8 appear as options when a logic
input module is installed in a slot.
State Condition (B State)
To set state condition B, select the states of the trigger sources in relation to the trigger level.

Determination Mode (Mode)
Set what kind of relationship must be established between period T and the specified reference times (Time or
T1 and T2) for the DL850E/DL850EV to trigger.
T < Time Period T must be shorter than the reference time (Time).
T > Time Period T must be longer than the reference time (Time).
T1 < T < T2 Period T must longer than reference time T1 and shorter than reference time T2.
T < T1, T2 <T Period T must be shorter than reference time T1 or longer than reference time T2.
Reference Times (Time, T1, T2)
You can set the reference times (Time, T1, and T2) within the following ranges.
Setting Selectable Range Default Resolution
Time 0.02 μs to 10000000.00 μs (10 s) 0.02 μs
0.01 μs T1 0.02 μs to 9999999.99 μs 0.02 μs
T2 0.03 μs to 10000000.00 μs (10 s) 0.03 μs
Trigger Level (Level) and Trigger Hysteresis (Hys)
Set these items for each trigger source.
These items are the same as the trigger level
and hysteresis of the simple trigger.
Trigger Hold-Off (Hold Off), Trigger Position (Position), Trigger Delay (Delay)
These items are the same as trigger hold-off , trigger position , and trigger delay
of the simple trigger.
