Modbus Master Simulator

Overview

Modbus Master Simulator is a professional Modbus TCP server application that provides advanced simulation capabilities for industrial automation testing and development. It supports holding registers, input registers, coils, and discrete inputs with configurable simulation modes including static values, ramp up/down, and sine wave patterns. Features include real-time value scaling (e.g., 0-100% → 0-1000), adjustable update intervals, slave device monitoring for coil mirroring, and comprehensive event logging. The intuitive GUI allows easy configuration of multiple registers and discretes, with save/load functionality for quick test scenario deployment. Ideal for testing Modbus clients, SCADA systems, and PLC communications without physical hardware.
