INMBSMID001I000 – Midea VRF and Commercial to Modbus RTU Interface for Single Unit

INMBSMID001I000 – Midea VRF and Commercial to Modbus RTU Interface for Single Unit. 

The INMBSMID001I000 gateway enables seamless bidirectional communication between Midea VRF or commercial air conditioning systems and Modbus RTU-based BMS or controllers. Designed to support one indoor unit, it connects directly to the XYE communication bus, ensuring reliable system integration.

With Intesis MAPS software, configuration becomes efficient and intuitive. The platform provides extended diagnostic features, fast auto-discovery of connected units, and the ability to define custom mappings. These functions ensure rapid commissioning, robust control, and long-term maintainability in industrial and commercial automation environments.

The interface supports simultaneous access to AC parameters and internal diagnostics, including error codes, operation modes, temperature setpoints, and running hours. The Modbus port uses EIA-485 standard and supports slave operation.
