5.3 Setting Using the Auto Configuration Function
The Auto Configuration function automatically creates parameters by detecting a slave
node in a DeviceNet network, which is a supplementary function for creating
parameters. The Auto Configuration function can reduce the load on the sequence
program for parameter settings.
When the Auto Configuration function is executed, it takes up to 60 seconds until it
completes.
To save the parameters to the flash ROM, execute it by setting Y17 to ON.
(1) Auto configuration operation settings (address 03F0
H
/1008)
Set the auto configuration type and maximum detection node numbers as
follows:
1) Higher byte
Set the auto configuration type.
00
H
: All configuration
01
H
: Additional configuration
(Default value: 00
H
)
2) Lower byte
Set the maximum detection node number.
00
H
to 3F
H
(0 to 63) (Default value: 3F
H
)
The following two auto configuration types are available:
• All configuration: Searches all the slave nodes in the network having node
numbers 0 to the maximum detection node number, except
the local node number, and saves them in the "parameters
for the master function" area. The areas after the detected
slave nodes will be cleared.
• Additional configuration: Searches all the slave nodes in the network having
node numbers 0 to the maximum detection node
number, except the local node number and the slave
nodes currently being set, and saves them in the
"parameters for the master function" area. The areas
after the detected save nodes will not be cleared.
The auto configuration is performed in the following sequence:
(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.
