Q.
[R Product] I Forgot My Password. What Should I Do? (Recovery Disk)

Product

A.
The R Series (TOPR / TOPRX / TOPRW / TOPRE / TOPRH) allows you to set an administrator password.
This can be configured via [Project] - [Security] in TOP Design Studio or directly on the device under [Control Panel] - [Security] from the menu screen.

This password is required to access the menu screen and to perform download/upload operations.

If the password is forgotten, there is no way to reset or retrieve it — not even through customer support.
The only solution is to create a recovery disk using an SD card in TDS and use it to reset the device.
Note: Performing recovery will erase all data on the device.

[How to Create a Recovery Disk]
1. Insert an SD card into your PC.
2. In TOP Design Studio, go to [Tool] - [Recovery Disk].

3. Select the SD card drive from the list, choose your product series, then click [Go].
→ This will generate the recovery disk.

[How to Perform Recovery]
1. Insert the SD card into the HMI device.
2. Set both DIP switches 1 and 2 (next to the SD slot) to the down position.
3. Recovery will begin when the device is power cycled.

You’ll see the message: "The system upgrade will take a few minutes. WARNING! Do not turn off the power."
After a few moments, the device will emit a continuous beeping sound (beep! beep! beep!) indicating that the recovery is complete.

4. Remove the SD card.
5. Return DIP switches 1 and 2 to the up position, then power cycle the device again.

You’ll be prompted with the touch calibration screen.
Complete the calibration by pressing and holding each target area.
Once calibration is done, the menu screen will appear — at this point, re-download your project file.

Important Note:
When selecting the SD card drive in TDS, make sure you choose the correct drive. Selecting the wrong one may erase data from another drive on your PC.

Q.
[R Product] I Can’t Select Objects While Editing. (Lock Setting)

Function/Development

A.
If you’re unable to select or edit objects on your screen during editing, it's likely because those objects are locked. Locked objects cannot be edited. This feature is useful when you want to prevent further changes to completed objects. To lock or unlock an object, right-click the object and select [Lock] or [Unlock] from the context menu. If multiple objects are locked, you can use [Unlock All] to release all locks at once. Alternatively, after selecting an object, wait for about 2 seconds. A pushpin icon will appear at the top-left corner of the object. Clicking this icon will also toggle the lock status. When an object is locked, it will be outlined with black dots, and the red pushpin icon will appear after 2 seconds. Clicking the red icon will unlock it. When unlocked, the object is editable. Clicking the blue pushpin icon again will lock it.

Q.
[R Product] Can PLC Communication Settings Be Configured in a TOP Project?

Product

A.
To enable communication between the TOP HMI and a PLC, a properly wired cable based on the correct wiring diagram must be connected, and the communication settings must be configured accurately. These settings can be configured directly on the HMI’s menu screen or they can be configured in the TOP Design Studio's project file and transferred to the HMI device. To configure communication settings in TOP Design Studio: 1. Open your project file in TOP Design Studio. 2. Go to the [Project] - [Property] menu at the top. 3. Select the [HmiSetup] tab on the top-right and check the [Use HMI Setup] option. 4. Click the [Edit] button to open the [Control Panel]. This control panel is identical to the one found on the TOP HMI’s menu screen. If this option is enabled, the settings will be applied to the HMI when the project is downloaded. After verifying the PLC’s communication parameters (e.g. Signal Level, Baud Rate, Data Bit, Stop Bit, and Parity Bit) and input the exact same values in the [Serial] screen. Any mismatch between the PLC and HMI settings will cause communication failure (e.g., timeout errors). If using the [HmiSetup] feature, you can also set the Start Mode (Menu/Run), Start Screen No, and Language under [Option] - [Project Setting].

Q.
How can I register my own images or text on the screen in [R Product] TOP Design Studio?

Product

A.
Registering Images In TOP Design Studio, you can add your image files by inserting an [Object - Image] onto the screen. After placing the image object, open its [Properties]. Click the button marked with a red rectangle to open the [Image Selection Dialog]. In the dialog, select [Local Library] and choose the image file from your PC to register it. Alternatively, if you have an image open in Paint, Photoshop, or another editor, you can select it with Ctrl+A, copy it with Ctrl+C, and then paste it directly onto the TDS screen with Ctrl+V. This will automatically create an image object with your image on the TDS screen. Registering Text If you have text in Notepad, Excel, or Word, select and copy it with Ctrl+C. Then, paste it onto the TDS screen with Ctrl+V. This will automatically create a text object with your copied text on the TDS screen. If you need further details or step-by-step images, please let me know!

Q.
Is it possible to configure redundant communication by connecting two PLCs to the [R Product]?

Communication

A.
Yes, you can configure redundant communication by connecting two PLCs to the [R Product]. In TOP Design Studio, go to the [Project] > [Properties] menu at the top. In the [Device Settings] section on the left, select the PLCs you want to use for redundancy. On the right, you will see the [Enable Redundancy] checkbox. Check [Enable Redundancy]. The Primary Option is for the settings of the first PLC. The Secondary Option is for the settings of the second PLC. With this configuration, if communication with the first PLC (Primary) is lost and a timeout occurs, the system will automatically switch to the second PLC (Secondary) after 5 seconds and continue communication. By using the redundancy function, communication will be maintained even if the first PLC fails, as it will automatically switch to the second PLC. When setting up redundancy, make sure that the communication parameters (such as Address Mode, Notation, etc.) for both the Primary and Secondary PLCs are the same. You can also configure the redundancy operation conditions (timeout, switching criteria, etc.) within the project.

Q.
I modified and transferred the screen design for [R Product], but communication is not working.

Communication

A.
Since you are using the same PLC and the same communication cable, if communication does not work after transferring the project file (screen design), it is highly likely that the communication settings have changed. Please check the following: 1. Check Communication Settings on the TOP Device Go to the menu screen on the TOP and open the [Control Panel] menu. If you are using serial communication with the PLC, enter the [Serial] menu and check the communication settings. If you are using Ethernet communication with the PLC, enter the [Ethernet] menu and check the settings. 2. Check Communication Settings in the TOP Project In TOP Design Studio (software), go to [Project] > [Properties]. The [Project Options] screen will appear. On the right, you will see the [HMI Settings] page. If [Use HMI Settings] is checked, click the [Edit] button and review the settings in the [Serial] or [Ethernet] menus. These settings will be applied to the [Control Panel] on the device when you transfer the project. After confirming and correcting the communication settings, enter the [PLC] menu and perform a communication diagnosis to check whether the connection is successful.

Q.
Are [Communication Diagnosis] and [Port Diagnosis] different?

Communication

A.
Yes, Communication Diagnosis and Port Diagnosis are different. 1. Communication Diagnosis This is a test to check whether communication between the controller connected to the TOP and the TOP itself is functioning properly. If the communication diagnosis fails or an error occurs, it is usually due to a problem with the cable between the TOP and the controller, or incorrect communication settings. In such cases, please refer to the communication manual and ensure all settings are correct. 2. Port Diagnosis This is a test to check whether the serial port of the TOP is functioning properly. Port diagnosis is also called a loopback test. If the data sent out from the TOP is correctly returned to the TOP, the port is considered to be functioning properly from a hardware perspective. Depending on whether you are using RS-232C or RS-422/485, you must short the relevant pins of the serial port with a clip or similar tool before performing the port diagnosis. If you run the [Port Diagnosis] without shorting the pins, an error will always occur. If communication does not work even though the communication cable and settings are correct, or if you suspect a port malfunction, perform this test. If an error occurs, please request after-sales service (AS).
