Modbus Sniffer Software

Modbus RTU Sniffer (aka Serial Port Monitor) is a powerful tool serving as an optimal solution for analyzing data transferred within Modbus communications. Thanks to Modbus Sniffer’s outstanding functionality, you can easily detect and resolve any problem you may face when providing Modbus testing and debugging. The distinctive advantage of the software is its ability to display and log all the data transmitted through COM ports available in your system.

With the advanced search and filter options, offered by this efficient Modbus Sniffer software, only relevant serial data will be shown to you. Another great feature is a built-in terminal used for executing text commands. Modbus Monitor is an easy-to-use app that supports different formats for exporting data and provides you with numerous significant options.

The software can be purchased as a Standard, Professional or Company Edition.

Here are the key Modbus Protocol Sniffer capabilities:

  • Modbus' data analyzing

    The moment the app connects to the required COM port, it starts analyzing serial data transferred through it. By monitoring serial ports in real time, you can track down emerging issues and react immediately. Even when a COM port is used by another application, you’ll still have no problem connecting to it with the software.

    All data, collected by Modbus RTU Sniffer, can be viewed in different modes, which greatly simplifies the process of data comparison and evaluation.
  • Simultaneous monitoring of multiple ports

    Modbus Sniffer is capable of recording data from several COM ports within the same monitoring session. That means, you can see several applications communicating with different devices through several serial ports simultaneously. Using the first in, first out method for data logging, the software makes it easy to analyze monitored communications.
  • Displaying data in different modes

    Captured data can be displayed in different visualizations. The software offers Line, Table, Dump, and Terminal views. Each visualization provides its own benefits, so, depending on your needs, you are able to choose whether to watch the data as recorded IRPs, displayed in a table, ASCII characters, or a plain text, displayed in lines.
  • Emulation of data transfer

    If you want to test the reaction of a particular device to a specific command, Modbus Sniffer will help you do this by simulating sending data to the required device from the monitored COM port the device is connected to. The software supports binary, octal, decimal, hexadecimal, and mixed data formats.
  • Comparing Modbus communication sessions

    It’s a really good idea to compare monitoring sessions if you need to get more accurate results within Modbus communication being analyzed. Once you receive Modbus data from your application, the software enables you to emulate its transfer to the serial port again. This way, you can see all differences between sessions and compare the data received.

    Without the Serial Port Monitor from Electronic Team, I would not have been able to easily and quickly see the operation of the several serial ports carrying data to the navigation program...
