TR30-G Tablet Recorder  Demo Site
  • Compact package
  • No need of dedicated application software other than a web browser
  • Flexible built-in I/O modules plus Modbus slave I/O

Model TR30-G is a web-based data acquisition system which enables users to view and access stored data via an internet browser. Freed from a dedicated display screen, accessibility and portability of the data is greatly enhanced. In addition, users can receive free benefit of ever-evolving state-of-the-art user interface and apps provided by tablet terminals: e.g. ultra-high resolution screen, intuitive touch panel operations, entering comments by dictation or hand-writing, capturing a screen shot and e-mailing, etc.

The compact logging module together with I/O modules can be mounted next to a PLC in a panel, at the same height and depth.


The R30 Series I/O modules are available for use with the TR30-G.

Compact Package Flexible I/O
I/O Extension via Modbus

The following types of I/O modules are available.

  • 16 Di or Do
  • DC voltage/current input, 2 or 4 points
  • Universal input, 2 or 4 points
  • T/C or RTD input, 4 points
  • Potentiometer input, 4 points
  • AC current input, 4 points

In addition, remote Modbus slaves can be connected up to 12 nodes.

At the maximum of 64 analog inputs (16-bit data), 64 discrete inputs, 64 discrete outputs, 32 pulse inputs (32-bit data) plus 32 function inputs (mathematical, logic, filter, etc.) are usable. At the maximum of 120 channels can be plotted on the charts and stored at the storing cycle of 1 minute. The fastest storing cycle is 5 milliseconds for 16 channels, 100 milliseconds for 32 channels.



Viewer Software TRViewer

The TR30-G has a large main memory of 4 GB (used up to 2.5 GB at the maximum) divided into 50 memory blocks just like chart books for a chart recorder.

Trend data is stored in binary format, and each memory block in the main memory is transferred to an auxiliary SD card memory in a regular interval, either in the binary format, or converted into CSV.

Files can be uploaded to a remote PC via FTP client or server function.

Automatic file delete function can be set to automatically discard the oldest files when less than 100 MB memory area is free.

The TRViewer program is available for Windows PC to view and manage historical trend graphs and convert binary format data into CSV.



  • E-Mail
    Pre-listed recipients can receive an e-mail notification with data values when a channel trips alarm threshold. Regular reporting is also available.
    At the maximum of 32 text message templates and 32 recipients can be set.
  • Daylight Saving Time (Summer Time)
    The TR30-G is adoptable with daylight saving time by specifying the beginning and the end of daylight saving time.
  • SNTP Client
    The internal RTC is automatically adjusted at the startup, at 0, 6, 12, and 18 hours of every day.
  • Modbus/TCP Slave
    Interfacing with SCADA or PLC as Modbus master is possible. Data stored in multiple TR30-G can be collected by a SCADA, or a PLC can be used to control the start/stop of the logging, to force memory block transition, to trigger a comment entry, etc.
  • User Defined Browser View
    User’s original web browser views can be developed using HTML and Javascript.

  • Basic Configuration with Wi-Fi
    Basic configuration composed only with TR30-G and a Wi-Fi access point.
    A tablet is used for simple field monitoring, while a PC may be used not only to monitor but also to build up a report by an user’s application.
  • Expanded Configuration with Wi-Fi
    The TR30-G (Modbus Master) can take in remote I/O data (Modbus Slave) on the Modbus/TCP network. Max. 12 slave modules.

* Create through user programs based on the trend data file retrieved from the SD card or via FTP

  • Internet
    Data can be accessed via Internet. Max. 4 client terminals can access the TR30-G at once. The clients only need an internet browser application.

ISP: Internet Service Provider
FTP (File Transfer Protocol): a file transmission function standardly equipped on the browser
*1. Create through user programs based on the trend data file retrieved from the SD card or via FTP
*2. A static IP or dynamic DNS is required.



  • Plant Field Maintenance
    Operators can bring in tablets and smart phones to access trend data while freely walking around the site.
    They can also transfer data to their PC via FTP or via SD card to build up daily/monthly reports using their own application software.
  • Test and Research
    Researchers can access data logged in a remote building while they work in their own office.
