The standard Color CVIM asserts an output line only if the tool fails.
Installation of the Color CVIM BLISTER-PAK option, however, adds a new
menu item to the
Envir/Cam → I/O → Output Assignment → Usage
menu, as shown in Figure 8.1. By toggling this menu item, you can select
either the
Active: Fail output function (the setting in the default
configuration) or the Active: Pass output function. For most blister
applications, you should select Active: Pass .

When Active: Fail is selected (and Results Trig: Disabled selected), the
Output Assignment from the Color CVIM module equipped with the Color
CVIM BLISTER-PAK option behaves exactly as it would with a standard
Color CVIM module; that is, the system asserts an output signal only when a
tool fails. The output line is “off” when the tool passes, and it is “on” when
the tool fails.
When Active: Pass is selected, however, the system’s output response is
essentially inverted; that is, it asserts an output line only if the tool passes.
Thus, the output line is “on” when the tool passes, and it is “off” when the
tool fails. (Note that a non–zero
Duration value, such as 25ms, has the same
effect on the duration of the “on” and “off” states as it does when Active:Fail
is selected.)
The Active: Pass selection affects only the following output assignments:
•
Results (line is “on” when a tool passes).
•
Machine Stop (line is “on” in absence of a Machine Stop condition).
•
Master Range (line is “on” when all tools pass).
•
Module Busy (line is “on” during module “ready” condition).
•
Trigger NAK (line is “on” as long as triggers are accepted).
