Modbus Simulator - Documentation
1. What is System Simulation?
System Simulation is the process of creating a complete digital copy of a real HVAC installation — not just individual device register values, but the entire system's behavior: how compressors start under specific ambient conditions, how pressures and temperatures evolve during load changes, how the system responds to faults, and how all these elements interact as an integrated whole.
When we say 'system,' we mean the full operating context: the compressor as both the primary executor of the HVAC process and as a measurement device; the I/O module measuring external environmental conditions; and the complex dynamic relationships that make every installation unique — different piping configurations, different refrigerant types, different ambient conditions, and different control strategies.
The Modbus System Simulator creates this digital copy by learning from your actual operational data. The result is a living, dynamic simulation that behaves like your specific system, not a generic approximation.
Figure 1 — Priority of focus: System first, then Simulation, then Modbus as the delivery layer
The priority is deliberate:
- System — What is being simulated: the complete HVAC environment, compressor behavior, I/O conditions, and all their interactions
- Simulation — How the behavior is created: state machine, trained interpolation tables, dynamic value generation from real data
- Modbus — How the data is delivered: TCP or RTU communication protocol that integrates the simulated components into your control network
Modbus is important, but it is the delivery mechanism — not the focus. The focus is on accurately reproducing the system itself.
