Discrete I/O Assignments
9–15
Output Status from Various +/– and Force Selections
Table 9.1 shows the output status (activated or deactivated) for each
combination of inspection results (true and false) and corresponding settings
of “
+/– ” ( Pos and Neg ) and “ Force ” ( No , On , and Off ).
Table 9.1 Output States from Various Inv and Force Selections
Inspection Results +/– Selection Force Selections *Output Status
Any Pos Off Deactivated
Any Pos On Activated
Any Neg Off Activated
Any Neg On Deactivated
False Pos No Deactivated
True Pos No Activated
False Neg No Activated
True Neg No Deactivated
*When the CVIM2 system is offline, all outputs (except the strobe output) are deactivated.
System I/O is the second of the four Discrete I/O devices. You can select it
as shown in Figure 9.10 (page 9–16).
When the System I/O format is on the monitor screen, all 16 rows of the
table are available for input or output signal assignments. The inputs and
outputs assigned in this panel are routed to the
System I/O connector on the
CVIM2 front panel.
Note that initially all of the rows are designated as outputs, “ Out 0 ” to
“ Out1 5.” To change any row to an input signal, just pick one of the “out”
boxes. When you do, the “out” box toggles to become an “in” box. Thus,
“
Out 0 ” toggles to “ In 0 ,” for example.
NOTE: Triggers should be assigned only to inputs 0 and 1 on the Module
I/O panel and inputs 0 to 3 on the System I/O panel. Other inputs should not
normally be assigned to these inputs. (See Discrete Inputs: Interrupt
Processing vs Poll Processing on page 9–3 for details.)
For information about selecting input and output signals, refer to the Module
I/O Functions section on page 9–4.
