CX-Process Tool version 5.1 or earlier. Therefore they cannot be down-
loaded to the Loop Controller.

Similarly, the following ITEMs can be used only when LCB01/05 version 3.5
or later, LCB03 version 3.5 or later, and CX-Process Tool version 5.2 or later
are used.

Note
al.
Either one of the following communications drivers can be selected to support
the connection with a PLC (Programmable Controller):
• FinsGateway
• CX-Server
Selection is also possible when CX-Process Tool is started from the Start Menu,
or when Start Only is selected from the I/O Table Window using CX-Program-
mer that was installed from the CX-One only.
When using the CX-Process Tool installed from the CX-One, the default setting
is to not display the dialog box for selecting the communications driver.
Note If Start with Setting Inherited is selected from the I/O Table Window using CX-
Programmer that was installed from the CX-One, CX-Server will be used auto-
matically as the communications driver.
The following table compares the special features of the communications driv-
ers.
FinsGateway
Host Link (SYSWAY-CV) or peripheral bus
(toolbus)
Supported
Supported
1 or higher (cannot be set to 0)
• The same COM port can be used for si-
multaneous online connections with ap-
plications using FinsGateway (such as
PLC Reporter and SYSMAC OPC Serv-
er).
Note The PLC's node address must be set to 0 when using CX-Server and connecting
directly to the PLC in a 1:1 or 1:N connection. (The 1:N connection is possible
with Host Link communications only.) On the other hand, the node address can-
not be set to 0 when connecting to the PLC through FinsGateway; the node ad-
dress must be 1 or higher.
If CX-Server was selected as the communications driver and a Function Block
File (.ist) was created for node address 0 with filename "Node00" in that project,
the project (multi-node file) cannot be opened if FinsGateway is selected later.

Must be set to 0 when the computer is
connected directly to the PLC
• The same COM port can be used for si-

such as CX-Programmer, CX-Protocol,
and CX-Motion.
