MODBUS RTU Communication Tester 1.10

A useful and efficient MODBUS RTU communication tester and troubleshooter utility that monitors COM ports in order to sniff the transferred data
MODBUS RTU Communication Tester is a simple, yet efficient program that can be used for troubleshooting MODBUS RTU communications. It reveals byte information concerning the transfers of data in a comfortable manner.

The program is able to monitor various connection types, including RS232, RS422 and RS485 and provides a user-oriented configuration regarding port selection and the registers assigned to a certain port.

MODBUS RTU Communication Tester is brought inside a portable archive, which means an installation process isn’t going to be necessary. However, maneuvering it requires advanced knowledge of MODBUS architectures, otherwise the expected results won’t be returned.

Concerning its appearance, the program adopts a simple, yet intuitive interface, where parameters are categorized by purpose in a way that doesn’t create confusion. First and foremost, you are required to choose the connection type, then to configure port options, such as baud rate, stop bit, parity selection and data format (which can be either 7 or 8 bits).

In the next steps, you should specify the MODBUS address, the transmission and response delay and the start register. If everything is configured properly, the program will display information related to transmitted and received bytes, in hexadecimal form.

It is up to you to interpret the resulting data, which may include significant clues on the issues that might impair with a MODBUS communication. Unfortunately, there’s no option to save the report.

In conclusion, MODBUS RTU Communication Tester can play an important part in diagnosing MODBUS enabled architectures and is minimally invasive on system resources. The software targets professional users, with the necessary tech know-how in handling this type of program.
