Setting Network and Node Addresses
Select the active function block file in the Project Workspace and select Net-
work Settings from the Settings Menu. The following dialog box will appear.
1. Set the network address to between 000 and 127 in the Network Address
Field and set the node address to between 1 and 32 in the Node Address
Field.
2. Click the OK Button.
Note Set the network address to 0 if the local network is connected to
Ethernet.
Note If Ethernet is used, manually set the above network address and node address
using the FinsGateway manual setting. If the manual settings are not made or
different addresses are set, no online connections will be possible.
After the above settings, select the LCU element (LC001-1 to LC001-3) and se-
lect Network Settings from the Settings Menu. The following dialog box will ap-
pear with the network address and node address already set.
1. Input the unit address between 16 and 31 in decimal into the Unit Address
Field. The unit address to be input is between 16 and 31 (10 and 1F Hex). In
other words, add 16 (10 Hex) to the unit number between 0 and 15 (0 to F
Hex) set with the rotary switches on the front panel of the Loop Control Unit
as a CPU Bus Unit.
2. Click the OK Button.
Note In addition to manually setting the addresses, as described above, they can also
be set automatically by searching for Loop Controllers connected to networks of
the PLC connected to the CX-Process Tool. Select the LCU element and then
select Find LCU/LCB from the File Menu. This can be performed even before
initializing serial communications. Refer to Automatically Setting Addresses
(see below) for details.
