Entry
Symbol Trapezoid evaluation element
The DIGIFORCE
®
9311 linearly interpolates the trapezoid entry
coordinates from the last measurement point outside the trapezoid
and the first measurement point inside the trapezoid.
If the measurement curve starts inside the trapezoid area, the
DIGIFORCE
®
9311 outputs the first measurement point (start value).
If the entire measurement curve lies outside the trapezoid area, the
DIGIFORCE
®
9311 indicates/outputs the value pair 909090/909090
and displays "<<<>>>" on the screen.
Exit
Symbol Trapezoid evaluation element
The DIGIFORCE
®
9311 linearly interpolates the trapezoid exit
coordinates from the last measurement point inside the trapezoid and
the first measurement point outside the trapezoid.
If the measurement curve ends inside the trapezoid area, the
DIGIFORCE
®
9311 outputs the last measurement point.
If the entire measurement curve lies outside the trapezoid area, the
DIGIFORCE
®
9311 indicates/outputs the value pair 909090/909090
and displays "<<<>>>" on the screen.
Note: If you have defined an entry side and/or an exit side, at least one value pair must lie inside the
trapezoid. If this is not the case, the DIGIFORCE
®
9311 assesses the trapezoid with an NOK
result.
