FOUNDATION SYSTEM

Multi-System Integration

CONTROL OBJECTIVE

Connect mixed brands and generations while defining point meaning, authority, alarms and sequences beyond the BACnet or Modbus connection.

Original concept visual of building controllers, gateways and multi-system data boundaries

WHAT THE SYSTEM MUST DO

Verifiable interfaces and control boundaries

BACnet and Modbus integration
Point and authority mapping
Network, time, alarm and trend coordination
Interface testing and acceptance boundaries

The operating problem

Buildings often contain systems from different brands, protocol families and generations. Reading values through BACnet, Modbus or a gateway does not resolve point meaning, units, write authority, alarm rules or fallback behavior.

The objective

For mixed systems, Kimma defines point semantics, authority, alarm ownership, sequence conditions and acceptance before connecting interfaces. Useful information remains visible while equipment safety and local control stay protected.

How the system works

Create an interface matrix covering addresses, data types, units, enumerations, read/write attributes, update rates and quality status, then verify points against field behavior.
Separate monitoring, setpoint, command and sequence authority. Equipment protection and fast local loops remain in their native systems; the BMS coordinates approved supervisory actions.
Align time, naming, alarm priorities and trends, and test normal, manual, fault and communications-loss conditions—not merely an online protocol connection.

The practical outcome

The result is a maintainable integration in which operators understand what each critical point means, who may change it, who owns its alarms and how cross-system actions fail safely. The interface record also supports future additions and platform changes.
