Overview

Visualization – up to 200 times faster with KNXnet/IP

When larger projects require the cyclic polling of large volumes

of data points for the purposes of visualization, this can often

lead to prolonged periods of waiting until the values are updated.

Use the LAN as the main and backbone line and link your

visualization PC to the LAN.

Visualization is then up to 200 times faster – and you can monitor

larger volumes of data points. No further need for data concen-

trators. The data volume is irrelevant and the LAN can easily

cope with that "little bit of KNX" on the side.

The solution:

The benefits:

• LAN as main and backbone line

• Visualization now up to 200 times faster

• High data volumes possible

• No data concentrators required

Proceed as follows:

• Commission the KNX devices, including the N 146 IP router

• Install visualization software

• Search for the N 146 IP router as visualization software and

connect

• Configuring the visualization

You require the following:

• N 146 IP router (5WG1 146-1AB01), 1 x per line

• 24 V power supply for N 146 IP interface (e.g. 4AC2 402)

• Ethernet network (LAN)

• PC LAN-capable

• IPAS ComBridge Studio visualization software

(see chapter "Display, Operation")

• ETS3 (current version see http://www.knx.org)

Note:

LAN stands for Local Area Network. In LANs, data transport is organized over

the IP (Internet Protocol) – the standard network protocol on the Internet.

Multicast-capable: Multicast telegrams can simultaneously operate several IP

devices in the LAN. In the case of network components (network switches,

routers) this requires the appropriate configuration.
