The auto configuration type and the maximum detection node numbers are set
as follows:
1) Higher byte

The following two auto configuration types are available:
• All configuration: Clears the "parameters for the master function" area, except
for the constant scan, then searches all of the slave nodes on
the network excluding the local node, from node 0 to the
maximum detection node number, and stores the result in the
"parameters for the master function" area.
• Additional configuration: Searches all of the slave nodes on the network, except
for the local node and the slave nodes that have been
already set, from node 0 to the maximum detection
node number, then stores the result after the
"parameters for the master function" area that has
been already set. The area after the detected slave
node is not cleared.
The auto configuration is performed in the following sequence. See Section 5.3,
"Setting Using the Auto Configuration Function," for details.
(a) Set the auto configuration type in the "auto configuration operation settings"
area.
(b) Set the auto configuration request (Y15) to ON.
(c) The auto configuration result is stored in the "parameters for the master
function" area.
