Function:
Product Change
The sensor can be commanded to load
inspections
from slots 1 to 15 using the
combination
of Product Change and Product Select
functions
of the discrete I/O pins.
Set the state of the Product Select pins as described in
on page 36. Then set the state of the Product Change pin
to
Active
when the sensor is in the Ready state. The sensor immediately loads the selected
inspection
and is ready to execute when it
receives a trigger. For Product Change to be successful, select at least one of the I/O pins to
function
as Product Select.
Product Select Inputs
The VE has four dedicated Product Select lines that can be thought of as making a Binary Code Decimal (BCD) table. Access
