I/O Map Register Assignment
This module requires nine contiguous 16-bit (3x) registers—eight for input data and
one for input status. The data registers formats are as follows:
NOTE: The data format is 16-bit integer values in the positive range and an integer
value with the MSB indicating a negative sign in the negative range.
* A range warning is issued when a channel input exceeds the rated input value. An
out-of-range bit is set when a channel input exceeds the rated input value by 2.34%
or when a broken wire is sensed on the channel. The warning bit is cleared when
the out-of-range bit is set.
