IM DL850E-01EN
Pulse Width Trigger (Enhanced)
The DL850E/DL850EV triggers according to a specified duration (achievement time) for which state condition B
has been met. The timing of the triggering varies depending on the determination mode.
Achievement time
Trigger
B
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 the state condition B achievement time and the
specified reference times (Time or T1 and T2) for the DL850E/DL850EV to trigger.
B < Time The DL850E/DL850EV triggers when the achievement time is shorter than the
reference time (Time), and the state condition changes to not met.
B > Time The DL850E/DL850EV triggers when the achievement time is longer than the reference
time (Time), and the state condition changes to not met.
B TimeOut The DL850E/DL850EV triggers when the achievement time is longer than the reference
time (Time).
B Between The DL850E/DL850EV triggers when the achievement time is longer than reference
time T1 and shorter than reference time T2, and the state condition changes to not met.
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 for B TimeOut
0.01μs
T1 0.01μs to 9999999.99μs 0.01μs
T2 0.02μs to 10000000.00μs(10 s) 0.02 μs
Triggering may not function properly when the interval between achievement times is less than 0.01 μs or
when the duration of the achievement time is less than 0.01 μs (Typical).
