Configuring a PLC’s System Settings
The PLC Setup Component can be selected to define the settings which govern the PLC’s
behaviour; 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 dialogue 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.

6. Select
the

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
dialogue 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.
