Modbus Simulator for Analysts, Testers, and Developers
Test and analyze your processes using Modbus Testing, a Modbus simulator with Modbus TCP and Modbus RTU simulation. A next-level Modbus scanner for all your testing needs.
All-in-one solution
Universal
Supports both Modbus TCP and Modbus RTU protocols. Includes both a Modbus slave simulator and a Modbus master simulator.
Easy
Simple to use, yet highly powerful for advanced users.
Next-Level
Enables the scanning for devices, recording data for analysis, and replaying data for testing purposes.
Dashboards & Analytics
Our tool offers live charting of your Modbus register, whether you are generating them inside the application or reading them from other sources. Offering the perfect tool for analysis inside the application or export your data to analyze elsewhere. Simply scan for devices, select the registers to be recorded and start analyzing!
Advanced Register Generation
Try one of our cookie cutter generators to simulate values for your registers, or generate your own values using a custom generator. Still not what you want? Record your Modbus slave device registers and simulate it with the included master simulator for testing use.
Simple Configuration Management
Save your configurations for slaves and masters, or copy over particular registers by importing them from other simulators. We want to make sure you never make the same configuration twice and this is how we make sure you never will.
