This is an excellent tool for testing Modbus device configurations. It offers a comprehensive suite of simulation and testing modules that are easy to use and customize. The RTU/ASCII master and Modbus TCP client simulator modules are particularly useful for testing data input and creating custom data types. The ability to add specific units and scale or comment data is also a great feature. Highly recommended for anyone working with Modbus devices.
Modbus Test Master 1.0.28.30 was available as a free download on our software library. The program lies within Communication Tools, more precisely Social. This tool was originally developed by ClampOn AS.
From the developer:
Modbus Test Master makes it simple to set up, document and test complex Modbus systems. Create device profiles and specifications, pick and choose registers freely. Define multiple data types, specify units, add scaling and comments.
Add as many instances of the devices you have to as many RTU, ASCII or TCP channels as you need. Prefer to see trends of one or multiple sets of values while testing?
You may want to check out more software, such as Testing Master, Automated Solutions Modbus/TCP Master OPC Server or Simply Modbus Master, which might be similar to Modbus Test Master.
