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.
