Case 2 The cycle duration is derived from the system parameter
“Earliest start of output after triggering” or from a long image
evaluation duration:
I0
O0
Cycle duration =
Earliest start of output after T
Wait for next trigger Cycle duration =
waiting for image eval
Wait for next trigger

Case 2
Settings of the system parameters:
1
Earliest start of output after trigger =
220 ms
2
Ignore trigger signal after ready for
operation = 110 ms
3
Start of image evaluation after trigger
= 20 ms
4
Function at O2 = external lighting,
start of lighting and duration of
lighting = manual
5
Start of lighting after trigger/cycle start = 40 ms
6
Duration of lighting = 100 ms
–
Earliest start of output is after trigger signal termination = Yes
– Reset outputs at outputs after “Ignore trigger signal” = Off
– Reset outputs at outputs during evaluation = No
