Model your plant
Compose equipment, water loops, I/O, and editable Signal Logic around the system you need to test.
HVAC simulation · Controller testing
Test your controls before commissioning.
Build an editable HVAC plant, connect your PLC over Modbus TCP or RTU, and test normal operation, faults, and recovery with recorded evidence.
Modular HVAC plants
External PLCs
Repeatable tests
From simulation to evidence
Give every control decision a test.
Connect your controller
Exchange real Modbus commands and simulated feedback with external PLCs through configurable endpoints.
Measure the response
Run timed Plant Tests, inspect recorded outcomes, and retain the evidence needed to explain a deviation.
Alarm / Fault Injection
Test what happens when something fails.
Challenge protection and recovery with targeted disturbances. Observe the response, check timing, and keep the evidence.
Explore fault scenariosTest runs saved fault scenarios in prepared projects. Creating or editing scenarios requires Engineering, or Starter for learning and evaluation.
Next Step
Take the system model into your controller test.
Explore the product, follow the engineering documentation, or request the Windows installer for an evaluation environment.
