Hi everyone,
I’m currently working on a project where I need to test communication with a real Modbus RTU master device (such as a PLC or an industrial controller). However, I don’t have a real Modbus slave device available at the moment.
Instead, I want to use my Windows 10 PC to simulate a Modbus RTU slave, and connect to the master device using a USB to RS485 converter.
My question is:
Are there any reliable Modbus RTU slave simulator tools for Windows 10 that can work over a USB-to-RS485 connection to communicate with a real hardware master?
I've seen tools like ModRSsim2, Modbus Slave by ModbusTools, and ModbusPal (Java-based), but I’m not sure if they support actual RS485 hardware communication and not just virtual COM port testing.
If anyone has experience simulating a Modbus slave this way, I’d appreciate your recommendations (especially free or open-source tools if possible).
Thanks in advance!
