Analog normal operating
ranges
(1)
(1) The over- or under-range flag will come on when either the High Clamp or the Low Clamp values are exceeded.
When either range flag is set, the module clamps the corresponding channel’s output to the High Clamp or the
Low Clamp value. Unless latched, the flag automatically resets when directed to a value between the High
Clamp and the Low Clamp values. The output channel value always returns to normal operation when directed
to a value allowed by the High Clamp and Low Clamp values (even if latching of the Clamp status bits is
enabled).
