DP Master Application Examples

The following table shows how to configure the various Flex I/O modules.
An entry of 000 means do not configure a length for that slot.

Configure the I/O address as a P address so that the data maps into the I or O
file in the SLC for fast access, and the status part of the address as a Q address
so that the data maps into the M area.

Assign an address for each slot with a configured length.
