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

).

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.
