4-2-1 Selecting the Communications Driver

238
The following initial settings are required in order to connect the CX-Process
Tool to the PLC online and enable the online functions described above.
Select one of the following communications drivers for the online connection
with the PLC (Programmable Controller):
• FinsGateway
• CX-Server
Note Select the CX-Server to use EtherNet/IP for the communications protocol.
The following dialog box is displayed when the CX-Process Tool is started from
the Windows Start Menu or when Start Only is selected from the I/O tables.
Using FinsGateway
Select FinsGateway as the communications driver.
Using CX-Server
Select CX-Server as the communications driver.
Note 1. The above dialog box will be displayed when the CX-Process Tool is started
while File – Show Drive Select Dialog – Display is selected. It will not be
displayed if File – Show Drive Select Dialog – Hide is selected. To change
the communications driver, select File – Show Drive Select Dialog – Dis-
play and then start the CX-Process by selecting Start Only from the Start
Menu or I/O tables. If the CX-Process was installed as part of the CX-One
(not independently), the above dialog box will not be displayed (i.e., File –
Show Drive Select Dialog – Hide will be selected) and the CX-Server will
automatically be used as the communications driver. To switch to the Fins-
Gateway, select File – Show Drive Select Dialog – Display and then select
FinsGateway at startup.
2. Projects created with CX-Server selected as the communications driver are
not completely compatible with projects created with FinsGateway selected
as the communications driver. The following points are incompatible be-
tween the projects created with different communications drivers:
• When CX-Server is selected as the communications driver and the com-
puter is connected directly to the PLC (node address set to 0), it won't be
possible to select FinsGateway and open the project later because Fins-
Gateway must have a node address setting of 1 or higher.
It is possible to open the project and use FinsGateway if the node address
is changed. Select CX-Server, open the project, change the node address
to 1 or higher (file name other than "Node00"), and save the project again.
Select FinsGateway and open the project.
• When a project has been created with FinsGateway selected as the com-
munications driver and that project is later opened with CX-Server se-
lected as the communications driver, the network address will be set to 0
automatically. After opening the project, reset the network address setting
in each node's function block file.
