Mitsubishi Melsec Serial Autodetect Wizard

Help Contents

Introduction

Serial communications can be difficult to set up because of the many combinations of setup parameters. Setup parameters include: Communications Port, Physical Wiring, Baud Rate, Framing, Handshake and so on.

The Mitsubishi Melsec Serial Autodetect Wizard can simplify the setup of serial communications. The wizard tries different combinations of communication parameters until a Mitsubishi Melsec device is found. The wizard can automatically:

Note: The Wizard will only work if the physical connection to the device is wired correctly. If you run the Wizard with an incorrectly wired connection, the Wizard will not detect anything. It is worth spending time checking the physical connection is correct before running the Wizard.

Using the Mitsubishi Melsec Serial Autodetect Wizard

1. Start Configuration Tool. Use one of the connection options on the Start Page to connect to Fernhill SCADA.

2. Select the Tag Window in the Configuration Tool.

3. Right click on the folder where you want to import the detected configuration. The Tag Window Menu opens:

The tag window context menu showing the autodetect option

4. Click Autodetect.... The Autodetect... Wizard opens:

Autodetect Welcome Page

5. Click Next.... The Choose Device Type or Protocol page opens:

Autodetect Choose Driver

Note: You can only detect one device type or protocol at a time.

6. Select Mitsubishi Serial then click Next>. The Choose Protocols page opens:

Autodetect Choose Mitsubishi Melsec Protocol

Note: Some Mitsubishi Melsec communication modules, for example QJ71C24, may signal a communication error if more than 1 protocol is selected. This is expected behaviour. If more than 1 protocol is selected, the wizard will be sending different frame formats to the module. Some of these formats will appear invalid to the module and may cause the error indicator to light.

7. Select the protocol formats you want the wizard to try, then click Next>. The Choose communication ports page opens:

Autodetect Choose Ports

Note: The list of ports available on your computer may be different to the list shown above.

To select a port either: double click the port name, or select the port and click >.

The Autodetect Wizard will try the port(s) in the order shown in the Selected Items: list. You can reorder the list using the up and down arrows.

8. Choose the port(s) you want the Autodetect Wizard to try, then click Next>. The Choose Baud Rates page opens:

Autodetect Choose Baud Rates

9. Choose the baud rate(s) you want the Autodetect Wizard to try, then click Next>. The Choose Framing page opens:

Autodetect Choose Framing

10. Choose the serial framing you want the Autodetect Wizard to try, then click Next>. The Choose Address Range page opens:

Autodetect Choose Address

11. Choose the address range you want the Autodetect Wizard to try, then click Next>. The Ready to Start page opens:

Autodetect Ready to Start

12. Review the autodetect parameters and, if you are satisfied with your selection, click Next. The Autodetect Wizard will start:

Autodetect In Progress

Note: If you selected a large number of options in the previous pages, the wizard will take a long time to run.

When the Autodetect Wizard has finished searching the progress bar shows Complete:

Autodetect Complete

13. If the Autodetect Wizard has found devices, you can click Next to review the results:

Autodetect Found Device

14. Click Finish to create suitable configuration to communicate with the device. Click Cancel to cancel the operation.  If you clicked Yes, expand the NewConfiguration folder to see the automatically generated tags:

Autodetect New Configuration
