Connection Destination Setting Change
Configuration to communicate with an Omron Ethernet host is possible in a specific system memory.
A screen for entering values into the system memory enables to change the setting without using
NB-Designer.
You only can change the communication setting in the NB unit, not the setting of the connection
destination unit itself.

Description
LW9685
Enter the number of PLC to connect. The number must start with 3 and
ascending number, not a PLC number as it is.
For example, If 3 is assigned to this address, the Ethernet host that has
the lowest PLC number is selected. If 4 is assigned, the host whose PLC
number is the second lowest is selected.
After the PLC number is set to this address, the information about the
target host, such as current IP address, is automatically set to LW9686
and higher address.
LW 9686 to
9689
Enter the IP address of connection destination.
LW9686 is the most significant byte of the IP address. Ascending
addresses represents the lower bytes in sequence.
For example, IP address 192.168.250.0 is set as: 192 is LW9686, 168
is LW9687, 250 is LW9688, and 1 is LW9689.
LW9690
Enter the port number of connection destination.
LW9691
Set the node ID of connection destination. Enter the least significant byte
of the IP address, i.e. the same value as LW9689.
LB9272
Change set values in the addresses above. To enable the settings,
change this address to ON and then, reboot the NB unit.
