SIMATIC Visionscape® Job:
EFPS =
Where:
VS Overhead is typically:
Or
EFPS =
In Table 1–2, EFPS is given in PowerStrobe with 1msec Integration time and Job
in full pipeline, meaning that the Job tools + idle processing time, i.e., less than
(IT + VFT + 0.5) above.
Full Pipeline = (AVT Avp Processing Time + IDT Inspection Idle Time +
LossLess Connection Overhead) < (IT + VFT + VSO) idle time is defaulted to
3% of the Inspection Time as defined in the VisionSystemStep property page.
