The unit configuration, which is stored in the unit memory (UM), can
be changed via the [Advanced] button in the "I/O map and unit con-
figuration" dialog or by specifying the settings in a user program.
See p. 36.
Before D/A conversion, the digital input values to the analog unit are writ-
ten to the CPU's output area (WY). Control flags are also allocated to the
CPU's outputs.
The I/O addresses in the table show offset addresses. I/O addresses actu-
ally allocated are based on the first word number allocated to the unit.
Example: If the first word number is 10, the address number for the digital
input value on channel 0 will be WY10.
