other words, add 16 (10 Hex) to the unit number between 0 and 15 (0 to F
Hex) set with the rotary switch on the front panel of the Loop Control Unit as
a CPU Bus Unit.
If the value is incorrect, the personal computer will not connect to the Loop
Control Unit.
Note In the CX-Process, input the unit address in decimal (between 16 and
31).
3. Click the OK Button.
Note It is necessary to set the unit address for the serial connection as well.
If the wrong unit address is set, a dialog box will appear with a mes-
sage during data downloading with error code 0401 or 0202.
Note 1. When the network address, node address, and unit address are set, these
addresses will appear in order on the right of the LCU element in the Project
Workspace.
Example
2. 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 ele-
ment and then select Find LCU/LCB from the File Menu. This can be per-
formed even before initializing serial communications. Refer to Automatical-
ly Setting Addresses (page 245) for details.
If a serial connection is used, it is possible to start FinsGateway Communica-
tions service with the following steps.
1. Select Activate Serial Port Driver from the File Menu. The following dialog
box will appear.
2. Input the name of the COM port of the personal computer and the baud rate.
The baud rate can be set to 9600, 19200, 38400, 57600, or 115200 bps but it
must be the same as that set in the CPU Unit in serial communications
mode, otherwise no communications will be possible.
Note Set the data length to seven bits, the number of stop bits to two, and
the parity to even as communications conditions.
3. Click the OK Button.
4. The following dialog box will appear.
On the right of node 01: Network address 001 and
node address 01 with a separation dot between
them
On the right of LC001-1: Unit address 16
