8.1.7 Point List For
Analog Input/
Output
Change
In the following table, the entry in the “Format” column indicates that the format of the
associated data point can be determined by looking up the entry in Table 7–11: Memory
Map Data Formats on page 7–72. For example, an “F1” format is described in that table as
a (16-bit) unsigned value without any decimal places. Therefore, the value read should be
interpreted in this manner
