modbus-debug

You can debug Modbus RTU communication by using a Python-based tool that leverages pymodbus and pyserial to read and write holding registers, input registers, coils, and discrete inputs over serial connections.

Scanning for slave addresses on a Modbus TCP device involves using a debugging tool to systematically query the network, allowing you to identify active devices and verify their communication status.

Yes, you can continuously monitor Modbus register values to troubleshoot embedded systems by running a debugging script that polls holding or input registers at intervals to track data exchange.

Yes, this Modbus debugging approach supports both RTU for serial communication and TCP for network communication, enabling comprehensive verification of data exchange across different embedded device setups.

To read holding registers from a specific Modbus slave address, you connect to the device via your specified COM port or TCP connection, set the slave address, and execute a read command for the desired register range.

To start manipulating Modbus registers in Python, you need to install the pymodbus and pyserial libraries, which provide the underlying communication functions for both serial and network Modbus protocols.
