Bit Shift Register

LAB #23

NAME ___________

Use I/O simulation in Logixpro to simulate the following process.

There are 16 outputs that we are controlling. O:2/0 O:2/15

Program in a shift register that clocks every 3 seconds. Three seconds is the amount of time that part stays in each station. Use proximity switch to indicate if the part is present.(I:1/0)

The data from the proximity sensor will be shifted to the left through O:2.0 every three seconds.

Hint: If proximity sensor is on, O:2/0 comes on first, three seconds later O:2/1 comes on if the sensor stays on.
