4.3. Gateway General Functionality
With this Intesis IN775FGL00xO000 gateway, you can easily integrate Fujitsu 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.
