4.3. Gateway General Functionality
With this Intesis IN776MHI⁎⁎⁎O000 gateway, you can easily integrate Mitsubishi Heavy Industries systems into
an installation based on Modbus TCP, Modbus RTU, KNX TP, BACnet/IP, BACnet MS/TP, or Home Automation.
To do so, the gateway acts as a server device of the installation itself, accessing all signals from each unit and
allowing control of the whole HVAC network.
The gateway continuously polls the HVAC network, storing in its memory the current status of every signal
you want to track and serving this data to the installation when requested. When a signal status changes, the
gateway communicates it to the installation, waits for the response, and performs the corresponding action.
A signal's lack of response activates a communication error, allowing you to determine which signal from which
unit is not working correctly.
