Closing a PLC
The Open / Project Device button on the toolbar acts as a toggle switch. To close a device,
simply reselect the Open / Project Device button on the toolbar (i.e. when the menu option
shows a tick against it and the toolbar button is depressed).
When the device is closed, the details displayed in the Connection part of the CX-Net Network Configuration tool
are removed.
Configuring a PLC’s System Settings
The PLC Setup Component can be selected to define the settings which govern the PLC’s
behavior; for example, connection mode. Select the
Configure PLC System Settings button
from the toolbar. Refer to Chapter 4 - PLC Setup Component for further information.
Alternatively, select PLC Setup from the PLC menu.
Scanning for PLC Connections
A serial scan can be performed which searches all PC COM ports to see if there are any currently attached PLCs
and, if found, what communication settings are being employed by those PLCs. This procedure is useful when the
configuration of the PLCs communication settings (i.e. baud rate) are unknown. Device information from the
results of the scan can then be copied into the CX-Server project, if required. Refer to
Chapter 8 - Dragging
Device Information into a CX-Server Project.
When the Scan Serial Ports for PLCs dialog is first displayed, it shows the results of the last scan to be performed
until the
Refresh pushbutton has been clicked. Use the following procedure to scan for PLC connections.
1, 2, 3… 1. Open a CX-Server project by selecting the Open button from the toolbar or create a new
project. If required, add a device to the CX-Server project by selecting Add Device from the
Project menu and edit the CX-Server project by selecting the Edit Project button from the
toolbar.
2. Select Scan Serial Ports for PLCs from the Project menu. The Scan Serial Ports for PLCs
dialog is displayed.
3. Select either individual ports or select the Select All pushbutton to scan all ports from the
Available Ports field.
4. Select either individual baud rates or select the Select All pushbutton to scan all baud rates
from the Baud Rates field.
5. Select either individual cable types or select the Select All pushbutton to scan all cable
types from the Cable types field.
6. Select the Next pushbutton; the Scan Serial Ports For PLCs dialog starts the scan. The
Status field indicates the current progress. On completion, all currently connected PLCs are
listed in the Drag and Drop Device Units field.
Note:
If changes are made to PLC connections after a scan has been made, select the Refresh
pushbutton to update the displayed list.
Dragging Device Information into a CX-Server Project
The scan operation described in Chapter 8 - Scanning for PLC Connections, picks up device information from the
physically connected serial port devices. Once a scan has been performed, the Scan Serial Ports for PLCs dialog
can remain open alongside the CX-Net Network Configuration tool. Dragging a device or network unit from the
Drag & Drop Device Units field into the Project Device field in the CX-Net Network Configuration tool allows
this device information to be added into the CX-Server project.
Use the following procedure to utilise a convenient shortcut for entering PLC details into a CX-Server project.
1, 2, 3… 1. Open a CX-Server project by selecting the Open button from the toolbar or create a new
project. If required, add a device to the CX-Server project by selecting Add Device from the
Project menu and edit the CX-Server project by selecting the Edit Project button from the
toolbar.
2. Perform a scan by selecting Scan Serial Ports for PLCs from the Project menu.
3. Select the required device in the Drag and Drop Device Units field.
