Design your program to monitor over/under alarm bits, and to take appropriate
action depending on your application requirements. You may also want to
monitor these bits while troubleshooting with your industrial terminal.
Bits 00-07 each represent an input for channels 1-8, respectively. For example,
bit 04 represents input channel 5. The module sets a bit (1) to indicate it has
detected an alarm condition. Refer to Table 7.D.
