I had been looking for a proper solution to test my PLC’s for such a long time. I found the generators for simulating my slaves especially useful.

Scanning for devices and recording all their data was super useful. I thought I had a well functioning system, however using this Modbus scanner, I found out it wasn’t one at all.

Dashboard and analytics user interface

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.

Configuration management user interface

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.
