Q.
[R Series] _1OFF Error After Conversion to TDS

Product

A.
An error may occur in TOP Design Studio (TDS) after conversion due to changes and upgrades in functionality. We apologize for the inconvenience.

The special address [_1OFF], which was available in XDesignerPlus, is no longer supported in TOP Design Studio, and therefore causes a build error.

To resolve this issue, please change _1OFF to another valid address (PLC or SYS).

For detailed instructions on how to modify the address, please refer to the attached manual.

Q.
[R Series] VNC (Remote Monitoring/Control) and FTP (Remote File Transfer)

Product

A.
1. VNC (Virtual Network Computing)

VNC allows you to monitor and control the screen of a TOP configured as a VNC Server from another TOP, mobile device, or PC.
The VNC Viewer is the application that enables remote access to the screen of a TOP running the VNC Server.

To use the VNC function, an Ethernet network connection is required:

-. Local Ethernet Network: A PC with an IP address in the same network range as the TOP can connect via VNC. Mobile devices can also connect using a wireless router’s Wi-Fi.
-. Public IP Network: Any PC with internet access can connect.
-. Multiple Connections: Several VNC Viewers can connect to the same VNC Server simultaneously.
-. Dual Functionality: A TOP can operate as both a VNC Server and a VNC Viewer (Client).

※ Note: VNC is supported on TOPR, TOPRX, TOPRW, and TOPRH models.

2. FTP (File Transfer Protocol)

FTP is a protocol based on TCP/IP that enables file transfer between a server and a client. Through an Ethernet network, files on the server can be shared and retrieved.
A TOP can operate as both an FTP Server and an FTP Client.

For detailed setup instructions, please refer to the attached manual.

Q.
[R Product] How to Connect Multiple TOP HMIs (N:1) to a Single PLC via MBUS

Product

A.
When a PLC is already connected to one TOP via serial (RS-232C/RS-422/RS-485) and you want to add additional TOP units without changing the PLC wiring, use MBUS.

What is MBUS?
MBUS enables N:1 communication—one controller (PLC) over serial, shared by multiple TOP HMIs via Ethernet—with simple configuration.

-. The first TOP that is physically connected to the PLC over serial is the [MBUS Server].
-. The additional TOP units (2nd, 3rd, 4th, …) connect to the Server over Ethernet and act as [MBUS Client].
-. There is no hard limit on the number of Clients, but performance decreases as more are added. We recommend 4 or fewer Clients for stable speed.

Project Compatibility
As long as the PLC model/settings selected in TDS ([Project] - [Property]) are the same across the TOP projects, MBUS will work.

The projects do not need to be identical in every detail.

Configuration Steps

A. MBUS Server (TOP #1 connected to the PLC via serial)
1. On the TOP HMI, open the menu: [Control Panel] - [Service] - [MBUS].
(Use the Exit button on the top menu to reach the TOP menu screen.)
2. Enable [Use MBUS Server].
3. Select and configure the serial port that communicates with the PLC.

[Figure. MBUS Server]

B. MBUS Clients (TOP #2, #3, #4, … over Ethernet)
1. On each Client TOP, go to [Control Panel] - [Service] - [MBUS].
2. Enable [Use MBUS Client].
3. Enter the IP address of the MBUS Server (TOP #1).

[Figure. MBUS Client]

Notes
-. TOP-VIEW does not support MBUS.
-. Clients communicate with the PLC through the MBUS Server over Ethernet; the PLC remains connected only to the Server via serial.
-. For best performance, keep Client count ≤ 4. (More clients, lower speed)

Q.
[R Product] How to Back Up Alarm Data to an SD Card

Product

A.
This guide explains how to back up alarm data stored in the TOP unit to an SD card.

1. Alarm Data Storage in TOP Unit
The backup memory in the TOP unit stores Log, Alarm, and Recipe data.

-. Capacity: Fixed at 512 KB (not expandable).
-. The memory allocation for alarms can be adjusted under: [Project] - [Property] - [Project Option] (Window) - [TOP Setting] - [Project Option] (Tab)- [Partition Setting].
-. Adjust the allocation according to the memory requirements of Log/Alarm/Recipe data.

If more storage is needed beyond the built-in memory, you can back up data using:

-. An SD Card, or
-. An optional module (TOPR_OPT_CAM32).

※ The TOPR_OPT_CAM32 accessory can be found on the website under: [Product] - [Smart HMI] - [ACCESSORY].

2. Backup Settings in TOP Design Studio

Alarm Backup settings are configured in: [Project] - [Alarm].

-. In the alarm screen, select a specific [Block] from the list on the left.
-. On the right, under [Information], you can check the [Storage Size].
-. The [Count] field shows the approximate number of alarms that can be stored in the TOP unit.
Ex) With 191 KB allocated, about 3,049 alarms can be stored.
※ Note: The actual number may vary depending on alarm messages and additional information.

3. Backup to SD Card

To back up alarms to an SD card:
1. In the [Backup] settings, set [Backup Storage] to [SD Card/Ext Cam32].
2. Configure [Deletion Unit of Old File].

When the alarm storage reaches capacity, the oldest 30% of alarm data is copied to the SD card as a CSV file, then deleted from the TOP unit.

-. CSV files can be opened in Excel.
-. File path : [HMIAlarmBlock1 (Block No.)]
-. File name : [2025-08-19 (Date)]_[A01 (Block No.)]_[000001 (File No.)]_ALARM (Custom File Name).CSV
※ If a CSV file for the same date already exists, new data is appended instead of creating a new file.

4. Notes on Backup Behavior
-. If [Backup Storage] is set to [None], backup will not occur.
-. When memory is full:
- The system deletes the oldest cleared alarm first, then saves the new alarm.
- If no cleared alarms exist, the oldest active alarm first, then saves the new alarm.

5. [SD Update Action]
If you remove the SD card and want to copy all remaining alarm data from the TOP unit:
-. Use [Effect & Action] - [Action] - [Special] - [Storage] - [SD Update].

This will:
-. Copy all alarm data from the TOP unit to the SD card.
-. Generate CSV files by date.
-. If a CSV file for the same date already exists, new data is appended.
-. After copying, the alarm data in the TOP unit is deleted.

6. SD Card Specifications
-. Recommended capacity: 32 GB or less
-. File system: FAT32 format
