10-18 Controlling I/O Over a ControlNet Network
Test the Example Application
You will test the example application by using a momentary switch to
simulate a parts sensor.
1. Wire the 1756-IB16 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 on the
1756-IB16 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 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.
This completes the scheduled I/O example.
