Modbus Slave & Device Simulator (v3.8)

Simulate up to 256 Modbus devices, generate dynamic test wave patterns, and validate PLC/SCADA code before site delivery.

  • Multi-slave emulation: simulate up to 256 virtual Slave IDs on a single serial port or IP interface
  • Full memory map simulation: Coils (0x), Discrete Inputs (1x), Input Registers (3x), and Holding Registers (4x)
  • Dynamic value generation engines: Sine wave, Sawtooth ramp, Square pulse, Random noise, or incrementing counters
  • Simulate Modbus exception responses (Illegal Function 01, Illegal Data Address 02, Illegal Data Value 03, Slave Device Busy 06) for fault-injection testing
