Understanding the Output Assignments
Remember that the F2-02DAS-1 module appears to the CPU as a 32-point discrete output
module. These points provide the data value and an indication of which channel to update.
Note, if either a DL240, DL250 or DL260 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
word that will be assigned to the module can simply be determined.
The individual bits in this data word location, represents specific information about the analog
signal.
Channel Select Outputs
Two of the outputs select the active channel.
Remember, the V-memory bits are mapped
directly to discrete outputs. Turning a bit OFF
selects a channel. By controlling these outputs, the
channel to be updated is selected.
