ComTest Pro

ComTest Pro is a super handy software designed for testing communication with MODBUS RTU devices. It works well with both Ethernet and Serial connections, making it a reliable choice for your needs.

Easy-to-Use Interface

The interface of ComTest Pro is really user-friendly! You’ll find it easy to navigate through just three simple steps. Plus, the tabs let you switch between connection modes without any hassle.

Manage Your Logs Effortlessly

With ComTest Pro, you can easily save or clear logs. You can also read or write registers and even view raw data collected by the software. This makes it super efficient for keeping track of everything!

Configure Your Connection

First off, you choose between ‘Serial’ and ‘Ethernet’ connections to start configuring the steps. If you're going with Ethernet, you'll pick the protocol (either ‘Modbus TCP’ or ‘Modbus over TCP’) and enter the ‘IP Address’ and ‘Port’ number. Don't forget to set up the ‘Delay’ and ‘Timeout’ periods in milliseconds too!

Serial Connection Settings

If you opt for the ‘Serial’ connection, there are more choices! You get to decide on the ‘Port’, ‘Baud Rate’, ‘Data Bits’, 'Parity’, and even ‘Stop Bits’. Plus, you can set options like ‘Echoback’, ‘RTS Control’, and 'Reverse CRC' to get everything just right.

Select Commands Easily

In Step 2, it's time to input your device and register numbers. Then you can choose what command you want to use—options include things like 'Read Holding Registers' or 'Write Single Holding Register'. It’s all pretty straightforward!

Error Checking Made Simple

You can also set a function code and turn on options like 'Loop Command' or 'Error Checking'. If anything goes wrong, there’s an option to show an error dialog so you know exactly what happened.

Start Gathering Data

The last step lets you hit that big 'Start' button to begin collecting information. Once you're done, you have options like copying data to log files or writing registers directly!

All in all, ComTest Pro is an easy-to-understand tool that will definitely help you test communication for MODBUS RTU devices effectively! For anyone looking for a reliable solution, download ComTest Pro here!
