2.
Select the Open/Close Project Device PLC button from the toolbar to open connections to
the device.
3.
Select the Show Unit Status button from the toolbar or select Unit Status from the PLC
menu.
4.
Select the Clear Log pushbutton to delete the entries in the error log.
5. Select the Close pushbutton to remove the dialog.
Note:
Unit status and error log data for Communications Units (e.g., Controller Link Units
and SYSMAC LINK Units) can be written to files in CSV format. Click the Save
button in the PLC Unit Status dialog box and the Save As dialog box will appear. Select
the CSV format and the folder in which to save, input the file name, and click the Save
button. The status of the Communications Unit and the error log data will be saved in a
CSV file.
This function allows network errors to be analysed from CSV files.
Note: With a C-series PLCs, the error log for a Communications Unit (e.g., Controller Link
Unit or SYSMAC LINK Unit) can be saved using PLC | Unit Status/Error Log.
Testing the Network Connection
Once network connections have been created, the network should be tested to ensure that all nodes are responding
properly. The following tests are available:
♦
Internode Echo-Back Test . This test checks the condition of a number of specific network and node address
and whether communications can be established;
♦
Broadcast Nodes Test . This test examines all nodes on the network and is available for Ethernet, Controller
Link and SYSMAC LINK only. This test may take some time for an Ethernet network which is not subject to
the same size restrictions as Controller Link and SYSMAC LINK. The results show all nodes found and the
PLC type if possible;
♦ Ping Node Test . Allows echo testing of a specific TCP IP address.
Select the required test from the associated button in the toolbar, either the Echo Back Test
button, the Broadcast Test button or the Ping Test button.
Communications Unit Setup
The Configure Communications Unit button from the toolbar is used for SYSMAC LINK,
SYSMAC NET and Controller Link setup options on SIOU units for C-series PLCs. These
options only describe settings that cannot be accessed via the IO Table component.
For CS1-series PLCs and CV-series PLCs, the setup allows SYSMAC NET, SYSMAC LINK and Controller Link
setup. This information is defined via the IO Table component; refer to
Chapter 3 - IO Table Component for
further information.
Select a unit type from the Unit Type field. If provided, select the Setup pushbutton to further configure
communications setup. Select the Close pushbutton to close the dialog.
SYSMAC LINK Settings
The SYSMAC LINK menu only appears when the end connection is the SYSMAC LINK network. It allows
settings specific to a SYSMAC LINK network to be made.
Network Status
The SYSMAC LINK Network Status dialog shows the nodes present on the network. It also indicates the
controlling server node. Use the following procedure to setup SYSMAC LINK Network Status settings.
