Output Channel Update Sequence (Pointer Method)
If the F2-8AD4DA-2 is installed in a local (CPU) base, all four output channels can be updated
on every scan. However, only one channel can be updated per scan if the module is installed in
an expansion, remote I/O, or Profibus slave base. The timing is synchronized with the timing
of reading the input channels, so each output channel can be updated every eight scans.
