Product description
The Power Supply System KNX PS640-IP combines the central functions of a KNX bus
line:
Power supply with throttle and bus communication
IP router and IP interface
The device has got two KNX interfaces, one for the “PLUS” functions of the power
supply unit and one for the IP router. The functions are registered at the bus separately
and parametrised in different product files (ETS).
The power supply unit of the KNX PS640+IP delivers a 29 V bus voltage for the KNX
system and 24 V DC supply voltage for 24 V devices. Special operating conditions such
as short circuit, electrical surge, overcharge or excess temperature are recorded and
may be read off on the display. The present power discharge is displayed as well. It is
possible to reset the connected bus devices directly by means of the key pad.
In addition all functions can be realised via the bus, too, e. g. the transfer of malfunction
messages and operating data and a time/period reset. Malfunction messages are stored
by the KNX PS640+IP.
The IP router of the KNX PS640+IP allows for forwarding of telegrams between
different lines via a rapid LAN (IP) backbone. The KNX PS640+IP therefore also takes on
the function of a line coupler.
In parallel, the KNX PS640+IP can be used as interface for accessing the bus via IP.
Like this, the KNX system can be configured and supervised from any PC in the LAN
(Tunnelling). Access via smartphone (KNX app) is also possible.
This device works according to the KNXnet/IP specification using the core, the device
management, the tunnelling and the routing part. The router of KNX PS640+IP has a
filter table and is able to buffer up to 150 telegrams.
Functions:
Delivers a 29 V KNX bus voltage (reduced), output current max. 640 mA, short-
circuit proof
Delivers 24 V DC (not reduced), output current max. 150 mA
Reset of a line directly on the device
Record of operating hours, overload, external overvoltage, internal overvoltage,
short circuit and excess temperature
Display of operating data bus voltage, bus current and temperature of the device
The display may be shown in German, English, French, Italian, Spanish or Dutch
Bus connection for data transfer (e. g. malfunction messages, operating data)
Possibility for reset and diagnostic via the bus
Routing: Transfer of KNX data via LAN (rapid backbone)
Line coupler function via LAN
Tunnelling: Configuration and supervising of the KNX system from any PC in the
LAN, access via smartphone (KNX app)

Configuration is made using the KNX software ETS. The product file, the data sheet and
the manual can be downloaded from the Elsner Elektronik homepage on www.elsner-
elektronik.de in the “Service” menu.

Application examples
IP Interface
Coupler function (KNXnet/IP Routing)
The Power Supply System KNX PS640+IP can operate as a line and/or backbone
coupler. In both cases, the LAN (IP) acts as a backbone.

5
KNX PS640+IP as a line coupler KNX PS640+IP as a backbone coupler
KNX PS640+IP as a backbone and line coupler
The physical address assigned to the
KNX PS640+IP determines whether the
device operates as a line or backbone coupler. If the physical address is in the form of
x.y.0 (x, y: 1..15), the router operates as a line coupler. If it is in the form of x.0.0 (x:
1..15), the router acts as a backbone coupler.

6
Attention: If the KNX PS640+IP is used as a backbone coupler (x.0.0), there must be no
KNX IP Router in the topology beneath it. For example, if a KNX PS640+IP has the
physical address of 1.0.0, there must be no KNX IP Router with the address 1.1.0.
If the KNX PS640+IP is used as a line coupler (x.y.0), there must be no KNX IP Router in
the topology above it. For example, if a KNX PS640+IP has the physical address of 1.1.0,
there must be no KNX IP Router with the address 1.0.0.
The KNX PS640+IP has a filter table and thus contributes to reducing bus load. The filter
table is automatically generated by the ETS.
Because of the speed difference between the Ethernet (10 Mbit/s) and KNX (9.6 kbit/s), a
far greater number of telegrams can be transmitted on IP. If several consecutive
telegrams are transmitted on the same line, they must be buffered in the router to avoid
telegram loss. The KNX PS640+IP 750 has a memory for 150 telegrams (from IP to
KNX/EIB).
Bus access (KNXnet/IP Tunnelling)
The Power Supply System KNX PS640+IP can be used as an interface to KNX. KNX can
be accessed from any point in the LAN. For this purpose, a second physical address
must be assigned in the ETS. Please refer to chapter “ETS Connection Manager”.

Setting of parameters in the ETS
Parameters of the IP interface
General
Device name [free entry]
The KNX PS640+IP can be assigned a name of your choice. The device name should be
descriptive (e. g. Line TF). It is used to search for and recognize a device.
Monitoring bus voltage failure disable • enable
If a KNX failure is detected, it is reported on the IP. Return of the bus voltage is also
reported.
IP address assignment automatic (DHCP) • manual
Automatic (DHCP): The IP address is automatically assigned on the DHCP, i.e.
additional settings are not required. To be able to use this function, there must be a
DHCP server in the LAN (many DSL routers have an integrated DHCP server).
Manual: In this case, the IP address, the subnet and the gateway IP address must be
entered manually.

15
IP configuration
IP Routing Multicast address
Byte 1 / 2 / 3 / 4 0 … 255
This address is used for routing telegrams on IP. The multicast IP address 224.0.23.12
was reserved (KNXnet/IP) at the IANA (Internet Assigned Numbers Authority) for this
purpose. If a different multicast IP address is required, it must lie within the range of
239.0.0.0 to 239.255.255.255.
IP address
Byte 1 / 2 / 3 / 4 0 … 255
This is the IP address of the KNX PS640+IP.

16
IP subnet
Byte 1 / 2 / 3 / 4 0 … 255
Enter the subnet mask here. The device uses the values entered in this mask to
determine whether there is a communications partner in the local network. If there is
no partner in the local network, the device will not send the telegrams directly to the
partner but to the gateway that routes the telegram.
IP gateway address
Byte 1 / 2 / 3 / 4 0 … 255
Enter the IP address of the gateway here.
Note: If the KNX PS640+IP will only be used in the local LAN, the entry of 0.0.0.0 can
remain unchanged.
Example of assigning IP addresses
A PC is to be used to access the KNX PS640-IP.
IP address of the PC: 192.168.1.30
Subnet of the PC: 255.255.255.0
The KNX PS640-IP is located in the same local LAN, i. e. it uses the same subnet. The
subnet constrains the IP addresses that can be assigned. In this example, the IP address
of the KNX PS640-IP must be 192.168.1.xx, where xx can be a number from 1 to 254
(with the exception of 30, which is already in use). It must be ensured that no numbers
are assigned twice.
IP address of the KNX PS640-IP: 192.168.1.31
Subnet of the KNX PS640-IP: 255.255.255.0

17
Routing (KNX -> IP)
Group telegrams (main group 0 to 13) block • route • filter
Block: No group telegrams of this main group are routed to IP.
Route: All group telegrams of this main group are routed to IP independent of the filter
table. This setting is for testing purposes only.
Filter: The filter table is used to check whether or not the received group telegram
should be routed to IP.
Group telegrams (main groups 14 and 15) block • route
Block: No group telegrams of main groups 14 and 15 are routed to IP.
Route: All group telegrams of main groups 14 and 15 are routed to IP.
Group telegrams (main groups 16 to 31) block • route
Block: No group telegrams of these main groups are routed to IP.
Route: An additional page appears on which the routing of main groups 16 to 31 can be
disabled or enabled in pairs.
Note: The group addresses of main groups 16 to 31 are reserved addresses that can be
used for special applications (e.g. in Easy Mode). These group addresses are not
available in the ETS.
Physically addressed telegrams block • route • filter
Block: No physically addressed telegrams are routed to IP.
Route: All physically addressed telegrams are routed to IP.
Filter: The physical address is used to check whether the received physically addressed
telegram should be routed to IP.
Broadcast telegrams block • route
Block: No received broadcast telegrams are routed to IP.
Route: All received broadcast telegrams are routed to IP.

18
Acknowledge (ACK) of group telegrams always • only if routed
Always: An acknowledge is generated for every received group telegram (from KNX).
Only if routed: An acknowledge is only generated for received group telegrams (from
KNX) if they are routed to IP.
Acknowledge (ACK) of physically
addressed telegrams
always • only if routed • answer with
NACK
Always: An acknowledge is generated for every received physically addressed telegram
(from KNX).
Only if routed: An acknowledge is only generated for received physically addressed
group telegrams (from KNX) if they are routed to IP.
Answer with
NACK: Every received physically addressed telegram (from KNX) is responded to with
NACK (not acknowledge). This means that communication with physically addressed
telegrams on the corresponding KNX line is not possible. Group communication (group
telegrams) is not affected. This setting can be used to block attempts at manipulation.
Routing (IP -> KNX)
Group telegrams (main groups 0 to 13) block • route • filter
Block: No group telegrams of these main groups are routed to KNX.
Route: All group telegrams of this main group are routed to KNX independent of the
filter table. This setting is used for testing purposes only.
Filter: The filter table is used to check whether the received group telegram should be
routed to KNX.

19
Group telegrams (main groups 14 and 15) block • route
Block: No group telegrams of main groups 14 and 15 are routed to KNX.

Communication settings in the ETS
If the IP-configuration of the KNX PS640+IP is valid the device can act as an interface to
KNX. The following configuration is necessary:
Select the button “Settings” and the tab “Communication” in the main window of
ETS4. All available connections are listed by “Configured connections”. Select the
desired connection.
The button “Local settings” enables the configuration of the individual address, which
is used for bus access.
A dummy device may be created in the ETS-project to reserve this address.
The KNX PS640+IP supports up to 5 connections simultaneously. An additional physical
address has to be reserved for every connection. The first additional physical address is
allocated (as shown above) to the connection in the ETS. The remaining additional
addresses can be assigned directly by the device, in which cast the learn button should
be pressed for at least one second. The automatic address allocation is performed as:
Connection 2 contains the next higher address from Connection 1,
Connection 3 the next higher from Connection 2
etc.
For example:
Connection 1 uses the additional individual address 15.15.250.
Connection 2 is automatically set to 15.15.251, connection 3 is 15.15.252,
connection 4 is 15.15.253 and connection 5 is 15.15.254.
The assignment of the additional individual addresses is shown by a fast blinking learn
led.
Note: It is necessary to check whether the additional individual addresses are unused
before they are assigned.
For new devices (i.e. in the factory settings state), only the additional individual address
of the first connection is active with the address 15.15.250. To support multiple
concurrent connections the additional address assignment is required.
