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.
Firstly, the name Modbus does not describe any hardware or software feature and is also not really a product. It is a communication protocol, developed by Modicon systems in 1979. You can use the protocol to transmit information between two or more devices via serial lines.
Modbus is a communication protocol developed by Modicon systems. In simple terms, it is a method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the Modbus Master and the devices supplying information are Modbus Slaves.
You could use Wireshark. Excellent tool. Modbus TCP supported.
