IOy Series integrates centralized control for AV, HVAC, and lighting systems, improving efficiency, reducing energy consumption, and enhancing room management at the international convention center.

Case Details

The international convention center has 15 multi-function halls (ranging from 80–500 m² each) and required:
1.Centralized control of AV equipment (projectors, matrix switchers, conference systems, etc.) in each hall
2.Intelligent management of environmental devices (HVAC, lighting, motorized curtains)
3.Interconnected control between subsystems
4.Status monitoring of all multi-function halls from a central control room

Hardware Configuration

Device Type	Model	Quantity	Function
Main Controller	IOy	15 units	Main control unit for each hall
Digital I/O Module	16DI16DO	30 units	Discrete control
Analog I/O Module	8AI8AO	15 units	Environmental parameter acquisition
Communication Gateway	BL100 Series	15 units	Protocol conversion

Implementation Details

1. AV Equipment Control
