Simply Modbus Slave 8.1

Simply Modbus Slave by Simply Modbus is a Windows-based tool that simulates a Modbus slave device for testing, commissioning, and troubleshooting Modbus master applications. It lets you define and edit coil, discrete input, input register, and holding register values, then observe how a master queries and interprets that data. The software decodes requests and responses in real time, showing both raw hex and human-readable formats, so you can quickly verify behavior and isolate issues.

Key features:

• Simulates a Modbus slave over serial connections (Modbus RTU/ASCII)
• Editable data tables for coils, discrete inputs, input registers, and holding registers
• Live monitoring of function codes, requests, and responses with hex and parsed views
• Configurable serial settings, including baud rate, parity, stop bits, and slave ID
• Traffic logging and timing insights to aid diagnostics and documentation

Designed for developers, integrators, and field technicians, Simply Modbus Slave provides a fast, reliable way to validate master implementations and replicate real-world device behavior during development and testing.
