2.2.1 Q-NETWORK
The XRGI® control system is based on two logical networks:
■ Q-net Control (control network)
■ Q-net Heat (heat network)
Both systems use the conventional hierarchical master/slave strategy, with the master controller alone being able to access the shared
resources unsolicited. The slave controller cannot access the shared resources of its own accord; it has to wait until it is asked by the
master controller.
All network modules have two RJ45 ports per board. The iQ-Control Panel is the master for the control network and hence for the
Power Unit and the Q-Heat Distributor. The Q-Heat Distributor is the master for the heat network and thus the interface between the
two logical networks. The Q-Heat Distributor therefore has two boards and four ports.
Each RJ45 port has two LEDs (e.g., the Storage Control is shown below):
The LED on the left (orange) indicates the connection status:
■ LED off = System off
■ LED Continuously on = Connected
■ LED Flashing = Communication
The LED on the right (green) indicates the operating status:
■ LED green = Everything OK
■ LED red = Unit is connected to the wrong network or there is no space for more units
■ LED flashing red = Error (refer to relevant product specifications)
The control network consists of the iQ-Control Panel (master), the Q-Heat Distributor and the gas safety circuit (both slaves).
The heat network consists of the Q-Heat Distributor (master) and the downstream members: Storage Control, Flow Master Control
and Boiler Control (all slaves). The members belonging to the network are looped via the Q-Network cable in series (not star-cabled).
Each Q-Heat Distributor can control up to 20 slaves, although there can only be one Flow Master Control in the network, but multiple
Storage Controls. Installations with multiple Power Units have their Q-Network modules linked by a Q-Network cable.
The iQ-Control Panel and Q-Heat Distributor continuously request data from network members every few seconds and update their
functionality. This means that a Storage Control can be added to the network during operation, for example.
Available Q-Network modules:
■ Q-Network Storage Control (storage control)
■ Q-Network Flow Master Control (discharge control)
■ Q-Network Boiler Control (boiler activation)
■ Q-Network VPP Control (virtual power plant control)
■
Q-Network Electric Heater Control
■ Q-Network Modbus Gateway
■ Q-Network storage tank with external Storage Control
