Understanding the I/O Assignments
Remember that the F2-4AD2DA module appears to the CPU as 16 discrete input and 16
discrete output points. These points provide the data value and channel identification. Note,
if either a DL240 or a DL250 CPU is being used, 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 into V-memory, the location of the data
words that will be assigned to the module can simply be determined.
The individual bits in this data word location represent specific information about the analog
signal.
Input Data Bits
The first twelve bits of the input word
represent the analog data in binary format.
