4.3. Gateway General Functionality
With this Intesis IN770AIR00xO000 gateway, you can easily integrate Hitachi VRF systems into an installation
based on Modbus TCP, Modbus RTU, KNX, 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 air conditioner unit and controlling
the whole AC network.
The gateway is continuously polling the AC network, storing in its memory the current status of every signal
you want to track and serving this data to the installation when requested. Also, when a signal status changes,
the gateway sends a write telegram to the installation, waits for the response, and performs the corresponding
action.
A lack of response from a signal activates a communication error, allowing you to know which signal from which
AC unit is not correctly working.
