Assignments
You may recall the F4–16DA–1 module requires 32 discrete output points from the
CPU. These points provide:
S
The digital representation of two analog signals per scan.
S
Identification of the two channels that are to receive the data.
S
Output enable control for all channels.
Since all output points are automatically mapped into V-memory, it is very easy to
determine the location of the two data words that will be assigned to the module.
