Protocols

Protocol simulators for real system testing

Connect your client to a virtual device. Each walkthrough includes setup, addresses, commands and expected replies.

Industrial

Protocol simulators for industrial clients, gateways, controllers, and integration software.

OPC UA simulator

Run a virtual OPC UA server, browse its nodes and subscribe to changing values from your industrial client.

Modbus TCP simulator

Run a virtual Modbus TCP device, read changing registers and test your client before connecting physical hardware.

Smart-building protocol simulators for commissioning, automation, and BMS validation.

BACnet simulator

Run a virtual HVAC unit over BACnet/IP. Write a setpoint, read it back and follow the supply-air temperature response.

KNX simulator

Run a virtual lighting zone over KNX/IP. Send brightness commands, read actual levels and see the dimming response.

Messaging simulators for device telemetry, cloud integrations, and automation flows.

MQTT simulator

Connect a virtual MQTT device to your broker, subscribe to live telemetry and test commands without physical hardware.

CoAP simulator

Read and write LwM2M sensor resources over CoAP. Configure the device and server ports, then verify a setpoint with your client.

HTTP simulator

Test GET, POST and PUT against a static weather API. Inspect JSON responses and verify profile and location updates.

EV charging and energy infrastructure simulators for OCPP, CSMS, and power-meter testing.

OCPP simulator

Connect a virtual OCPP 1.6J charge point to your CSMS. Verify boot registration, status updates and meter values.

Lab instrument simulators for SCPI-driven multimeters, oscilloscopes, and power supplies.

SCPI simulator

Connect your SCPI client to a virtual multimeter. Query voltage, change its value in SPX and verify the next reply.

Bluetooth Low Energy and embedded device simulators for firmware and integration testing.

BLE simulator

Read temperature and write a setpoint on a virtual BLE peripheral, using SPX with a host Bluetooth adapter.
