Understanding the Output Assignments
Remember that the F2-02DA-1 (L) module appears to the CPU as a 16-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 be simply 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
its channel. By controlling these
outputs, the channel(s) to be updated
can be selected.
Y35 Y34 Channel
On Off 1
Off On 2
Off Off 1 & 2 (same data
to both channels)
On On None (both channels
hold current values)
