Network Node of INDIV-5 AMR
Application
Ordering
Combinations
The INDIV-5 AMR network node is used to receive and handle the data transmitted by INDIV-5 Heat Cost Allocator of the AMR system. In small plants, one network node suffices as a data collector. In larger plants, or when consumption data shall be read out from a remote location, an M-bus interface for connection to a gateway is required. The NNB-Std network node is battery powered, the mains powered version is available for special applications.
The network node is a component of the AMR system. It has been designed for use in buildings to create a radio network for receiving and storing the data transmitted by the consumption
meters installed in the building. Communication between several network nodes is via radio also so that no wiring is required. All measured values acquired by the consumption meters are continuously exchanged within the network, which means that every network node stores the current consumption values, the values read out at the end of the month, and the set day values of all metering devices on the network. Owing to this operating principle, all network data can be read out at any of the nodes, or a INDIV-5 AMR gateway for remote data transmission can be used with any of the nodes.
Functions
•Reception and storage of the data transmitted by the consumption meters
•Automatic creation of a network with up to 12 network nodes (with a maximum of 500 consumption meters)
•Passing on all relevant consumption values to all network nodes on the network
•Communication via the INDIV-5 AMR gateway

|
|
Receiver and transmitter are used for receiving consumption data and forwarding them to other network nodes of the network. The memory stores the consumption data. It is protected against temporary power drops (e.g. mains power failure or replacement of the main battery) by a backup battery. The network can be read locally via the M-Bus interface.
NNB-Std node is battery operated, while the mains powered version requires a mains power supply 100 - 230 VAC.

Basic design
The network node consists of 2 major sections: the base and the housing with the electronics. It is thus possible to mount the base prior to commissioning, enabling the electrical installer to connect the mains powered network node to the mains network.
At the time of commissioning, the electronics section is snapped on and the electrical connections are made.
Wall-mounted section
The wall-mounted section of the network node NNB-Std contains only the main battery. The wallmounted section of the mains powered network node contains the power pack and possibly an optional RS232 interface.

Display Explanation
Delivery status. Switch to install mode by pressing the button MODE (> 2 seconds).
This is the normal operating mode of the data collectors: telegrams from the metering devices can be received, stored and handled further by the network.
The receiver is always active to ensure fast communication. This mode is automatically activated in the case of mains powered operation. It
M |
can also be started manually with the ACT26 service tool. |
|
In installation mode, the radio network will be built up automatically. Metering devices that transmit installation telegrams in this operating mode will be registered in the network. This mode is started by pressing the MODE button (> 2 seconds).
|
The extended Installation mode will register all metering devices |
|
that transmit either installation or data telegrams. This mode is |
M |
useful if network is expanded later. |
|
Same as installation mode, except that connections are built up only by devices with the same network signature.
This mode restores radio connection to lost or manually registered metering devices. This mode starts automatically.
Extended search mode2)
Delete mode2)3)
M
This search run is used to restore the radio connection to lost or manually registered metering devices. Starting from version 2.2 this mode can also be started manually by setting jumper 1 (in the plug field) and pressing the MODE button ( > 2 seconds).
Same as installation mode, except that all registered metering devices which are transmitting installation telegrams will be deleted (meter replacement).
1)In battery powered network nodes this mode is terminated automatically after eight hours.
2)This mode is terminated automatically after eight hours.
3)Possible only with the software ACT26 version 2.0 or higher.
