Understanding the I/O Assignments
The F2-8AD4DA-1 module appears to the CPU as having 32 discrete input and 32 discrete
output points. These points provide the data value, channel identification and settings for
resolution, range, and track and hold feature. These bits may never have to be used, but it may
be an aid to help understand the data format.
Since all output points are automatically mapped to V-memory, the location of the data words
that will be assigned to the module can simply be determined.
The individual bits in these data word locations represent specific information about the
analog signal. (The specific memory locations may vary, depending upon the slot where the
F2-8AD4DA-1 module is located.)
