1User notes
This manual is necessary for the proper operation of the device and should be stored at
the place of use.
This manual must be read carefully before commissioning, installation and mounting as
well as before changing the configuration setting of the device. The notes in the corre-
sponding sections must be observed.
It is supplemented by the short manual for the WEM-KNX Gateway.
1.1 Target group
This operating manual is intended for operators and qualified specialists. It must be ob-
served by all persons who use the device.
Installing and configuring the device may only be carried out by persons that have the
necessary training or instruction.
It is recommended that you participate in the standardized courses of a KNX-certified
training center before installing, programming and commissioning a KNX system. Here,
the participant acquires the necessary knowledge and skills through practical exercises,
which are also necessary for troubleshooting.

2Safety
2.1 Proper use
The gateway is intended for DIN rail assembly and installation in a control cabinet (plus
applicable regulations) as well as continuous operation together with a KNX power sup-
ply.
2.2 Security measures
▪When planning and constructing electrical installations, the relevant guidelines, rules
and regulations of the respective country must be observed.
▪The device may only be installed and put into operation by an electrician or authorized
specialist.
▪Observe the safety instructions and warnings.
▪Use only suitable tools according to IEC60715 for assembly.
▪In the event of faults or error messages, the causes must be found and the error or
failure must be corrected immediately.
▪Electrical work may only be carried out by professionals for electrical installations.
▪Accessibility to the device must always be guaranteed for reasons of usability and in-
spection.
Normal operation
▪After connection to the KNX bus system, the device works as intended.
▪After its first connection, the device works with default settings and can be configured
for normal operation.
▪The configured device will then work as intended for normal operation.
▪The display of the device must be clearly visible and readable.
2.3 Disposal
At the end of its useful life, the product described in this manual is classified as waste
from electronic devices and cannot be disposed together with the general residual waste.

3Product description
The WEM system consists of several different devices (WTC, SG, etc.), hereinafter re-
ferred to as WEM devices. Each of these WEM devices contains one or more modules
(module 1, module 2, etc.). The WEM/KNX Gateway enables central control and moni-
toring of WEM devices via the KNX network. To do this, the gateway must be connected
to the system device of the WEM system (via IP). The gateway then provides the bi-di-
rectional data exchange between WEM and KNX TP1, and is used to convert the data.
The data and settings of the WEM devices can be read and updated over the KNX net-
work or vice versa. Data conversion is designed for up to 62 WEM devices. The sending
of data on KNX side is configurable. The firmware can be updated via the IP network (by
using a HTML browser).
3.1 WEM Interface
The data of devices are read out regularly from the WEM system to be stored in the
gateway. For each communication object, it can be set whether a newly saved value is
sent to the KNX bus only on request or automatically. If the automatic sending of a group
object is selected, for numeric values a sending difference can also be set (so that no
unnecessary telegrams are sent when differences are too small). Thus, when the send-
ing difference is set and a parameter value exceeds this difference (between new and
last stored group object value), the value is sent via the communication object to the con-
figured group addresses in the KNX network.
3.2 KNX Interface
On the KNX side, the gateway simulates a KNX device and behaves like a further device
of the KNX system. When a group object of the KNX network changes, this change is re-
ceived via the corresponding communication object, then stored in the gateway and (ac-
cording to the setting) sent to the WEM system to update the corresponding value in the
WEM device.
3.3 IP Interface
Via Ethernet/IP, the gateway can also be accessed directly. For information about actual
settings and addresses stored in the gateway, a web frontend is available. It can be ac-
cessed by a HTML web browser. For example, the device is displayed in the Windows
network and a double-click opens the web frontend in the default browser. All connec-
tion-relevant information is shown here. Also, a table containing the devices of the WEM
system including module addresses (stored as a *.csv on the SD card of the system de-
vice) is displayed in a user-friendly format. Programming mode can be activated and de-
activated remotely, without having to press the on-device programming button. With the
update function, the gateway firmware can be updated via IP. The web frontend can also
be accessed via both the IP address and the MAC address.

5Assembly and disassembly
The device is intended for the DIN rail assembly in distribution boxes. Only mount on
suitable top-hat rails (TH35) and use a suitable tool according to IEC60715 for assembly.
The device has the protection type IP20, is intended for indoor installation and may only
be installed in dry environments. The device must be protected from moisture, dirt and
damage.
Accessibility to the device must always be guaranteed for reasons of usability and in-
spection. In particular, the display must not be obscured in order to be able to detect
faults or error messages immediately.
In case of damage (during transport, storage) no repair must be carried out and the
housing must not be opened. Do not connect damaged devices.
▶Please return a damaged device.
Procedure
▶If necessary, write down the MAC address before installation (see next image).
▶
▶Pull the fastening clip down with a screwdriver.
▶Place the device on the upper part of the rail.
▶Press the device against the rail until it is vertically placed.
▶Press the attachment clip upwards until it snaps in.
Disassembly
▶Pull the fastening clip down with a screwdriver.
▶Remove the device from the rail.
NOTE
