Note: All of the remaining signal functions (except Strobe, Module Busy,
and Trigger NAKs) can be configured to produce a pulse whose duration
depends on the number of milliseconds that you assign to the Duration
parameter.
•
Results: This signal occurs when the results of a tool inspection exceed
the warning and/or fault limits. (The tool must be assigned to an output
line that has already been assigned the Results function.)
You can assign the Results signal function to any unassigned output line.
As noted above, the Results signal function must be assigned to an output
line before any tool can be assigned to that line. Thus, if you wanted
inspection results from Ref. Line # 2 to be assigned to output line #10, you
would first have to assign the Results signal function to output line #10.
Note: You can assign the inspection results from any tool to an output line to
which you have already assigned the Results signal function.
•
Data Valid: This signal occurs when the Color CVIM system has
completed an inspection. Data Valid signals (the “data”) are stable on all
output lines assigned to the Results signal function. Data Valid goes low
after the next trigger or the selected Duration time.
Note: Data Valid does not indicate whether an inspection has passed or
failed. That is the task of the output lines assigned to the Results signal
function.
You can assign the Data Valid function to only one output line.
•
Trigger NAK: This signal occurs when the Color CVIM system receives
a trigger input signal, but cannot process that trigger. The signal goes low
upon the next “accepted trigger”.
You can assign the Trigger NAK function to only one output line.
•
Master Fault: This signal occurs when any (one or more) analysis tools
in the Color CVIM system detects a Fail condition.
You can assign the Master Fault function to only one output line.
