Protocols

Protocol simulators for real system testing

Use SPX protocol simulators to validate integrations against behavior-rich digital twins before hardware or building systems are available.

Industrial

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

OPC UA simulator

Validate OPC UA integrations against realistic nodes, namespaces, subscriptions, and scenario-driven system behavior.

Modbus TCP simulator

Emulate Modbus TCP behavior with realistic registers, timing, scaling, reads, writes, and fault conditions.

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

BACnet simulator

Rehearse BACnet smart-building integrations with realistic objects, properties, schedules, alarms, and deterministic replay.

KNX simulator

Simulate KNX sensors, actuators, schedules, and group-address traffic before onsite commissioning.

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

MQTT simulator

Simulate MQTT device behavior with realistic topic updates, retained messages, reconnect flows, and automation interactions.

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

OCPP simulator

Simulate OCPP 1.6 charge points and central systems with realistic boot notifications, transactions, meter values, and reconnect scenarios.

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

SCPI simulator

Simulate SCPI lab instruments including multimeters, oscilloscopes, power supplies, and analyzers from major vendors.

REST endpoint and constrained device simulators for HTTP, CoAP, and IoT integration testing.

CoAP simulator

Simulate CoAP server endpoints with realistic resource trees, observable attributes, and LwM2M integration.

HTTP simulator

Simulate HTTP REST endpoints with deterministic responses, dynamic payloads, and controllable latency for integration testing.
