The default Time setting for inputs is 5ms. In this case, the CVIM2 system
will not recognize a trigger signal whose leading edge occurs earlier than
5ms after the leading edge of the previous trigger signal.
For output signals, the Time parameter designates the minimum duration that
an output signal remains active. The default Time setting for outputs is
25ms.
To change the input or output setting, pick the appropriate box in the Time
column. When you do, the “calculator” pad appears, as shown in Figure 9.7.

To change a time setting using the calculator, pick the button, then
enter any new number from 1 to 9999. After entering the number, pick the
button. When you do, the new number will appear in the Time box,
and the calculator will disappear.
NOTE: Setting an output pulse duration of 0ms has a special effect; namely,
it results in a non–pulsed output, which means that an output will remain at
the level to which it was set by the results of the last inspection cycle. The
output will change to the opposite level only when a subsequent inspection
result changes. For example, an output assigned to a tool “fail” function will
remain active after receiving a tool “fail” signal, and it will go inactive only
after the corresponding tool passes an inspection.
