Discrete I/O Assignments

9–6

You can assign more than one input signal from the

Input Signals

list to a

single discrete I/O input. For example, you could assign both

Toolset

1.Trigger

and

Toolset 2.Trigger

in Figure 9.3 (page Figure 9.3) to discrete

input “

In 0

” in the

Module I/O

editor.

You can assign a trigger input signal to only one discrete I/O input. For
example, if you assign

Toolset 1.Trigger

to discrete input “

In 0

,” as shown

in Figure 9.3, and then assign that same input signal to another discrete I/O
input, it will be removed from “

In0

.”

To remove a trigger input signal from the discrete I/O editor, pick its name in
the

Inputs Signals

list, then pick the

button.

Bank Switch Input Selection

The

Bank Switch

input function is used to activate either cameras 1, 2, and

3 or cameras 4, 5, and 6. (Normally, this function should be assigned only to
the

System I/O

panel, as an input, on one of lines 4 through 15. Lines 0

through 3 on the

System I/O

panel, and lines 0 and 1 on the

Module I/O

panel should be reserved for trigger inputs. See Discrete Inputs: Interrupt
Processing vs Poll Processing
on page 9–3 for details.)

DV Reset Input Selection

The

DV Reset

(data valid reset) input function is intended for operations in

which the CVIM2 system is connected to an Allen–Bradley PLC

 through

the

Remote I/O

front panel connection.

The

DV Reset

function is assigned as an output from the PLC in the

Remote I/O

panel (an input to the CVIM2 system). It is one of the

“handshaking” signals used between the two systems. For details about its
use, refer to the CVIM2 Communications Reference Manual.

In1 – In8 Input Selections

Input selections

In1

through

In4

(or

In1

through

In8

if the “

tsin

environment variable is set to 08) can be configured as general purpose input
signals that can be used in math tool formulas and “

Condition

” selections in

the toolset edit panel. In a math tool formula, these inputs return a logic “1”
when active, and a logic “0” when inactive. In a

Condition

selection, these

inputs, when active, enable the corresponding tool to execute, and when
inactive, prevent a tool from executing.
