Test the Example
Application You will test the example application by using a momentary switch to
simulate a parts sensor.
1. Wire the 1756-IB16I digital input module as shown in the following
figure:
2. Restore the RSLogix5000 software and place the controller in Run
mode.
3. Repeatedly press and release the momentary switch at IN-0 (Count)
on the 1756-IB16I digital input module. Each time you press the
switch you should see the Parts_Count accumulated value
increment on the screen and the LED display of the OB16I output
module increment in binary.
4. Press and release the momentary switch at IN-1 (Reset) on the
1756-IB16 digital input module. You should see the accumulated
value of the Parts_Count reset to zero and all of the LEDs on the
1756-OB16I output module turn off.
