OUTPUTS
PRODUCT REFERENCE GUIDE 27
OUTPUTS
The three outputs can be configured as NPN, PNP, and Push-Pull (default setting). They
are short-circuit protected and the maximum load is 100 mA.
Output 2 and Output 3 serve as GOOD and NO GOOD Object signals. By default, they
stay active for 10 ms.
Output 1 serves as Data Valid signal. It is activated 1 ms after the GOOD or NO GOOD
Object signal activation, and deactivated 1 ms before the GOOD or NO GOOD Object
signal deactivation.
The output activation length can be set via Smart-VS WebApp on the Settings page.
Digital I/O diagram
Image acquisition starts on the Leading edge of the input trigger signal (default, can be
changed to Trailing edge via Smart-VS WebApp).
A Debounce time can be set on the Smart-VS WebApp to reject noisy trigger signals.
Each trigger event corresponds to a Data Valid signal indicating that the Output signals
can be sampled.
The inspection result, i.e. a GOOD or NO GOOD object detected, is always available after
50 ms from trigger (response time).
If a Debounce time greater than zero has been set, the device response time is 50 ms
plus the trigger Debounce time.
Overrun conditions (see "
) are signaled raising both the
GOOD and NO GOOD output signals.
NOTE
Data Valid timing details
The Data Valid signal is raised 1 ms after the GOOD or NO GOOD signal is raised.
It is lowered 1 ms before the GOOD or NO GOOD signal is lowered.
*default, adjustable via Smart-VS WebApp
Although not strictly necessary, it is recommended to connect and pro-
cess all the output signals in order to have complete system information
for diagnostics and troubleshooting.
