■

Overview

The level of automated applications also increases in the area

of building automation. Customers are keen to use components

from the field of industrial automation for the automation of

infrastructure facilities. This is now possible using

SIEMENS IP/Ethernet components.

■

Benefits

Use of tried and tested industrial components in the field of

building automation, i.e. utilization of building automation data

for the automation of factories. Simple transfer of configuration

data from ETS3.

■

Application

Automation and monitoring of buildings using KNX devices

with components from the SIMATIC product range.

■

Function

Modules for communication of a SIMATIC S7 with KNX bus over

IP/Ethernet using a KNXnet/IP interface:

• N 146 IP routers

• N 148/21 IP interfaces

• N 350E IP controllers

• N 151 IP viewers

The KNX/EIB2S7 program package comprises modules for

communication to the IP router/interface/controller/viewer and

an editor for user-friendly parameterization of the modules.

Addressing is implemented over group addresses on the side of

KNX and with DB and DW on the side of SIMATIC. Assignment

of the various address terms to one another is implemented

largely automatically in the KNX/EIB2S7 Editor.

One SIMATIC S7 can be connected to up to 5 KNXnet/IP interfaces,

which permits the monitoring, operation and reading of a total of

up to 7000 group addresses (depending on control type and the

number of KNXnet/IP interfaces connected).

The modules also support the cyclic reading of values in 5 different,

freely configurable cycles (10 min. - 1 x daily).

The following data point types are supported:

The following controllers can be used with an additional Ethernet CP:

• S7 314

• S7 315-2 DP

• S7 317-2 DP

• S7 319-3 PN/DP

• S7 412-2 MPI/DP

• S7 414-2 MPI/DP

• S7 416-2 MPI

The following Ethernet CPs can be implemented:

• CP 343-1

• CP 443-1
