Design your program to monitor over/under range 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 and 10–17 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 out of range
condition. Refer to Table 7.C.
