Initial Settings
3. If necessary, the Network Settings Dialog Box can be displayed by clicking
the Settings (S) Button next to the network type.
The port name (COM port number) can be selected in the Driver Tab. Also,
the baud rate and data format can be set to match those of the connected
PLC.
When the computer is being connected directly to the PLC, leave the node
address set to 0 (the default setting) in the Network Tab. (It will not be pos-
sible to open this project later with FinsGateway selected as the commu-
nications driver without changing the node address to a non-zero setting.)
Note When CX-Server has been selected as the communications driver, set the node
address to a non-zero value in the Network Settings Dialog Box before compiling
the Monitor tag file or CSV tag file. Select Change PLC from the Settings Menu
to display the dialog box. (If the computer is connected online, return the node
address setting to 0.)
1. After completing the settings described above, select the title (LC001-1 to
LC001-3). Select Network Settings from the Settings menu and the follow-
ing dialog box will be displayed.
2. Input the unit address in decimal (16 to 31) in the unit address field. Set the
value calculated by adding 16 (10 Hex) to the CPU Bus Unit unit number
setting (0 to 15, or 0 to F Hex) set on the front of the Loop Control Unit.
If the unit address setting is not correct (16 + the unit number setting), it will
not be possible to connect the Loop Control Unit online.
Note The unit address is input in decimal (16 to 31) with the CX-Process
Tool.
3. After inputting the unit address, click the OK Button.
Note The node address must be set whether a Host Link (SYSMAC WAY)
or Peripheral Bus (Toolbus) connection is being used. If the node ad-
dress setting is incorrect, an error will occur in downloading opera-
tions and the following error message will be displayed in the dialog
box: Error occurred during Clear All. ERROR CODE 0401 or 0202.
Note When CX-Server has been selected (Host Link or Peripheral Bus connection),
the PLC model and CPU that were set in the Change PLC Dialog Box will be
displayed next to the title in the Project Workspace. Also, the unit address setting
of the Loop Controller will be displayed next to the LCU/LCB element name, as
shown in the following diagram.
The initial Unit settings are the same as the settings for FinsGateway, although
the Peripheral Bus connection can be used to connect to the CPU Unit only. Set
the CPU Unit's serial communications mode to Peripheral Bus mode.
• Turn OFF pin 4 (or the PRPHL for a CS1D Duplex System) of the DIP Switch
when using the peripheral port.
