6Connection possibilities
The WCM-COM 1.0 home can only be connected via network cable. This is described in
detail below.
It may be advisable to consult a network administrator or IT expert to carry out this
configuration. Incorrect configuration of the router could leave the complete (home)
network being accessible by anyone on the Internet.
The WCM-COM communicates via http in the network, which runs unencrypted. Safety
relevant transmissions, such as https, are not possible.
6.1 Network – Ethernet
The WCM-COM is equipped with a network socket. This is used for direct connection on
site to access the local (home) network, and also for remote connection.
Direct connection
▶ Make a connection between Laptop and WCM-COM using the network cable
provided.
9The PC recognises the new network connection. The network address is obtained
within approx. 60 seconds and a connection is made.
9This is a connection with “limited or no connectivity“ (possibly indicated by yellow
warning sign at the connection icon in the taskbar), which is correct for operation
with WCM-COM.
This connection serves as the communication basis for the WCM-COM.
▶ Websites are accessed via web browser.
▶ Target address: Enter “WCM-COM” into the address line of the browsers.
9Start page or password query (see Ch. 7.3) for the system connected is opened.
Direct connection by network cable offer a reliable way of testing the network connection
and the network capability of the WCM-COM. If the interaction of these components
which are included in delivery functions correctly when directly connected to a computer
or laptop, the surrounding network (router, switch, network cable, etc.) should be
examined if a connection is not made wirelessly.

83279302 ▪ 2/2012-12 ▪ Mot 17-32
Measures if connection is not made
If an automatic network connection is not established when the WCM-COM is connected
to the laptop, the following should be carried out:
▶ Check LEDs on the network sockets of the WCM-COM and PC.
9Green LED lights up permanently.
9Orange LED flashes at irregular intervals.
On the hardware side the connection is therefore made, and the settings for the network
must be checked (in this case for Microsoft Windows):
▶ Start
▶ System control
▶ Network centre and release centre
▶ Manage network connections
▶ Select LAN connection, to which the WCM-COM is connected.
▶ Properties
▶ Properties of element “Internet protocol (TCP/IP)“ – IPv4
9Generally: Enable “Obtain IP address automatically“
9Generally: Enable “DNS Server Address automatically“
9Alternative configuration: Enable “ Automatically assigned, private IP address”
Measures if website is not displayed
If in spite of a network connection to the WCM-COM the start page of the browser
(Internet Explorer 8) is not displayed, the connection settings in the browser must be
checked:
▶ File
9Offline operation must not be enabled (not ticked).
▶ Extras
▶ Internet options
▶ Connections
9Enable “Never select connection“
▶ LAN settings
9Disable “Use Proxy Server for LAN”
Integration into a (home) network
▶ Make connection between WCM-COM and Router (or Switch).
▶ Activation and administration of new participant in network may be necessary.
See instructions of router.
9The WCM-COM is accessible by the participant in the (local) network.
▶ Access to websites via web browser.
▶ Target address: Enter “WCM-COM” into the address line of the browsers.
9Start page or password query (see Ch. 7.3) for the system connected is opened.

Remote access via the Internet
It may be advisable to consult a network administrator or IT expert to carry out this
configuration. Incorrect configuration of the router could leave the complete (home)
network being accessible by anyone on the Internet.
It is possible to access the WCM-COM from any PC or Laptop with Internet connection.
▶ Make a connection between the WCM-COM and the router.
▶ The router must maintain a permanent connection to the Internet.
▶ Router configuration to permit access to the WCM-COM.
9The system is accessible via the Internet by entering the public IP address into the
address line of the browsers.
The IP addresses of (private) Internet connections are usually changed daily. A dynamic
Domain Name System (DNS) is recommended to allow the WCM-COM to be addressed.
On the one hand this provides an individual clear text address (for example:
www.Example.DNS Provider.de), and on the other hand the new IP address is assigned
to this URL (Internet address) after every IP change.
The router can automatically update the IP address of a dynamic Domain Name System.
Please refer the operating instructions of the router for the configuration and setting
required.

7.2 User interface
Each of the three possible ways of communication leads to a uniform and identical user
interface. A current web browser (e.g.: Internet Explorer, Apple Safari, Mozilla Firefox,…)
is required as software on the PC.
7.2.1 System prerequisites
The computer used must meet the following prerequisites to be able to operate the
WCM-COM:
▪ Interface: USB or network connection
▪ Software: Internet Explorer 8 / 9
Mozilla Firefox 5 – 11
Google Chrome 17 / 18
A Flash Player (version 8 or higher) is required for data loggers
(graphics) and solar outputs.

▪ Process value: non editable temperatures or conditions
▪ User: editable user defaults or setpoint values
▪ Expert: editable parameters, in-depth knowledge required
Alterations are entered on the user and expert pages.
▶ A premature page change discards any changes entered.
▶ Confirmation is only given by clicking the “Apply” button.
