Signal sequence with system parameters
The signal sequence using system parameters in the
“Free run” evaluation mode could appear as follows.
Power
Trig. ignored,
wait O0=1
Immediate start of evaluation,
since trigger is still 1
Cycle duration =
Earliest start of output after
Cycle start +
Wait for next trigger Cycle duration =
Waiting for image eval

Fig. 4/9: “Free run” evaluation mode – Signal sequence using system parameters
Settings of the system parameters:
1
Earliest start of output
after cycle start=220ms
2
Ignore trigger signal
after ready for operation=65ms
3
Start of image evaluation
after cycle start=20ms
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
– Reset outputs at outputs after “Ignore
triggering signal” = Off
– Reset outputs at outputs during
Analysis = No
