Details
These attributes are used to read or write to the operation status digital I/O overrun registers. Reading a status
register returns a value. The binary equivalent of the returned value indicates which register bits are set. The
least significant bit of the binary number is bit B0, and the most significant bit is bit B15. For example, if a value
of 1.02600e+03 (which is 1026) is read as the value of the condition register, the binary equivalent is
0000 0100 0000 0010. This value indicates that bit B1 and bit B10 are set.

A set bit indicates that the specified digital I/O line generated an action overrun when it was triggered to generate
an output trigger.
