12.2 Three Pulse Set Overview

The Three Pulse Set uses the same I/O configuration as the standard One Pulse Set, but requires a different
timing scheme. Instead of a single product change pulse, three product change pulses will be required, one
for 100’s digit of the program number, one for the 10’s digit, and another for the 1’s digit. Corresponding sets
of pulses on the Product Select line are also required, as shown below:

The timing diagram above shows the example for the product number 211. The minimum pulse width for all
the timing is 1 ms to guarantee that the vision sensor will see the transitions. The valid number of pulses for
each place is 0 – 9. If an invalid memory location is selected (or one which does not store a valid inspection
file), the ‘Current Inspection’ number will be set to -1 and the sensor will be kicked out of Run mode. At this
point, a Product Change to a correct inspection file will get the sensor back into Run mode and inspecting.

12.2.1 Product Select in Three-Pulse Configuration

To use the product select option in the 3-pulse configuration follow these steps.

1. Select Hardware Input in the Select tab of the Run Screen.
2. Configure an I/O for Product Change.
3. Select 3-Pulse set.
4. For the Input of Inspection to be selected, there are three sets of pulses and the pulses are setup

in the following manner:

• First set of pulses are for the 100's digit.
• Second set of pulses are for the 10's digit.
• Third set of pulses are for the 1's digit.

The use will need to assert the Product Change signal for each set of pulses. To do this, the Product Change
signal must be asserted and held while the pulses representing the digit are being sent, and released after the
last pulse is given. Valid range of pulses for all digits is 0 - 9.
