Program Functional Check (Optional)
Monitor the status of input channel 0 to determine its configuration
setting and operational status. This is useful for troubleshooting when
the blinking channel LED indicator indicates that an error has
occurred.
If the Module Status LED indicator is off, or if the Channel 0 LED
indicator is off or blinking, refer to chapter 7.
For more information see chapter 5, chapter 7, and chapter 8.
