CV-series PLCs also have routing tables which, unlike the C-series, are not dependent upon the networks
(SYSMAC LINK, SYSMAC NET or Ethernet or Controller Link) to which they are connected. These tables are
known as FINS routing tables. A direct connection is known as a Local Routing Table. A network connection is
known as a Network Routing Table.
C-series PLCs linked to a SYSMAC LINK network are unable to communicate with a different network and
therefore do not have a routing table; however, C-series PLCs linked to a SYSMAC NET or Controller Link
network do have this capability and so have an associated routing table. These tables are known as SYSMAC NET
and FINS routing tables respectively.
Data Link Tables provide a means of allowing a network of devices to share information. The manner in which
this information is distributed in a system depends upon the network to which the table relates. The SYSMAC
NET network contains one node acting as the ‘parent’ node or Data Link server (containing the Data Link table),
unlike the SYSMAC LINK network where a copy of the Data Link table is sent to all nodes on that network. The
Controller Link network operates in a similar manner to SYSMAC LINK except that the network is split into two
areas with each node being associated with one or other of these areas. Data is then copied to each node in the
related area
. Refer to Chapter 10 - Data Links for further information regarding Data Link Tables.
For moving, resizing, maximising, minimising and closing windows, refer to Microsoft Windows online help for
further information.
Access to the CX-Net Network Configuration tool is either from the invoking application or from the Start
pushbutton on the Microsoft Windows taskbar.
To close the CX-Net Network Configuration tool, select the Close button in the title bar.
CX-Net and CX-Server Projects
All device information is contained within a CX-Server project file. Once the file has been opened, the PLCs listed
in that CX-Server project can be opened and the devices on their networks manipulated. CX-Server projects can
be manipulated from the CX-Net Network Configuration tool.
Creating a New CX-Server Project
A new CX-Server project can be created from the CX-Net Network Configuration tool. Use the following
procedure to create a new CX-Server project.
1, 2, 3…
1.
Select New from the Project Menu. The Create Project dialog is displayed.
2.
The CX-Server project must be saved before it can be edited. Enter a file name in the File
name field. An existing CX-Server project can be overwritten by selecting a .CDM file
displayed in the Create project dialog.
3.
Select the Save pushbutton to save the new project or the Cancel pushbutton to abort the
operation. CX-Server files have a .CDM extension.
Opening an Existing CX-Server Project
CX-Server project files can be retrieved using a standard File Open dialog. To close a currently open file, create a
new CX-Server project or select
Close from the Project menu.
Use the following procedure to open a CX-Server project file.
1, 2, 3…
1.
Select the Open button from the toolbar to open a CX-Server project file.
2.
A standard File Open dialog is displayed. Select a file from the Open dialog, followed by
the
Open pushbutton. PLC Memory files have a .CDM extension.
A list of the most recently opened CX-Server project files is displayed in the Project menu.
Note: Select Save As from the Project menu to save a project open in CX-Net under any
desired name.
