the bit condition is set (1).

3.4.3 Open-Circuit Flag Bits (OC0 to OC7)

Bits OC0 through OC5 of word 6 contain open-circuit error information for
channels 0 through 5, respectively. The bit is set (1) when an open-circuit
condition exists. See Open-Circuit Detection on page 4-3 for more information
on open-circuit operation.

3.4.4 Over-Range Flag Bits (O0 to O7)

Over-range bits for channels 0 through 5 are contained in word 7, even-numbered
bits. They apply to all input types. When set (1), the over-range flag bit
indicates an input signal that is at the maximum of its normal operating range for
the represented channel or sensor. The module automatically resets (0) the bit
when the data value falls below the maximum for that range.

3.4.5 Under Range Flag Bits (U0 to U7)

Under-range bits for channels 0 through 5 are contained in word 7, odd-
numbered bits. They apply to all input types. When set (1), the under-range flag
bit indicates an input signal that is at the minimum of its normal operating range
for the represented channel or sensor. The module automatically resets (0) the bit
when the under-range condition is cleared and the data value is within the normal
operating range.
