A Trip function event can be initiated to automatically enter the latched
channel value into the ND 2100G database when an edge is detected
by enabling auto trip in the formula function.
Example:
The horizontal position of a label on a box will be measured by
latching the value of C1 when the label edge is recognized by a
photoelectric sensor C2 connected to edge line # 2. When the edge
of the label is detected, dimension A is automatically entered into
the ND 2100G database by an auto trip event.
A = XLatch(C1,2,1)
