Discrete I/O Assignments

The signal names appearing in the center scrolling list are described briefly
as follows:
•
Pass –– This signal occurs when the system has processed all tools and
has found that all have passed their inspection tasks.
•
Fail –– This signal occurs when the system has processed all tools and
has found at least one tool that failed its inspection task for any reason.
•
Tool n –– This is the generic name for an inspection tool. When you
highlight “
Tool n ,” a list of tool results selections appears in the right
scrolling list (the selections are detailed below).
•
Strobe –– This signal, when assigned to an output, delivers a
strobe–firing pulse after receiving and processing a trigger signal.
•
Trigger ACK –– This signal occurs after the CVIM2 system has detected
a trigger signal. It indicates that the inspection will be processed.
•
Trigger NAK –– This signal occurs after the CVIM2 system has detected
a trigger signal. It indicates that the inspection will not be processed.
•
Data Valid –– This signal occurs after the inspection is complete and the
outputs have a valid state.
•
DV Overrun –– This signal is generally assigned in the Remote I/O
panel as an output to an Allen–Bradley PLC
. It indicates that the
CVIM2 system did not receive a Data Valid Reset signal from the PLC
before a new set of inspection results became available; thus, the new set
of inspection results has overrun the previous set.
The signal names appearing in the right scrolling list pertain to inspection
results from the tool selected in the center panel. The specific set of names
appearing in this list depends on the specific tool type (such as gage or
window) depicted by the
Tool n selection in the center panel. Execute ,
Pass , Fail , and Fail High are among those names typically appearing in the
right panel (refer to the various “Tool Inspection Results and Math Tool
Formulas” sections in Chapter 6 and Chapter 7 for explanations of these
names within the context of the specific inspection tool types).
To select an output signal, highlight a signal name in the left scrolling list. If
you highlight either
Module Ready or Bank State , no additional names
will appear in the center list; thus, you can pick the button at this time.
If you highlight one of the toolset names in the left list, however, additional
names will appear in the center list. At this point, you must highlight a signal
name in that list. If you highlight any name except a tool name, no additional
names will appear in the right list; thus, you can pick the
button at this
time. When you do, the highlighted signal name will appear in the Discrete
I/O Editor panel, as shown in Figure 9.6 (A) on page 9–11.
