4 Commissioning
4.1.2 Establishing connection with the controller
Setting the IP address
Each of the connected devices (controller and communication partners) in an Ethernet network or
with a point-to-point Ethernet connection requires a unique IP address. This can either be obtained
automatically (DHCP) or generated (Auto-IP) or assigned statically. In the following, "communication
partner" refers to a PC or laptop.
You can integrate the controller in an existing Ethernet network. To do this, you only need to establish
the physical connection with a standard Ethernet cable. Provided DHCP and UPnP are activated on
the controller (factory setting), the controller is also automatically detected on the network and can
immediately be operated via a PC located on the network.
Setting DHCP/Auto-IP
IP addresses can be obtained dynamically in a network from a DHCP server or, for example, in
the case of a PC direct connection, can be automatically self-generated without DHCP by the two
communication devices (e.g., PC and controller). DHCP and UPnP are preset in the controller at the
factory for automatically obtaining an IP address from a DHPC server or for automatic IP address
generation. To establish the connection to the controller, it may only be necessary to make a few
settings on the communication partner (e.g., PC or laptop). Settings using the Windows 7 operating
system as an example:
1. Press the Windows Start button and select Control Panel.
2. Select Network and Sharing Center.
3. Select Change adapter settings.
4. A list of the available network adapters is displayed. Open the properties on the adapter to which
the controller is connected (e.g., click with the right mouse button).
5. Select Internet Protocol version 4 (TCP/IPv4) and press the Properties button.
6. Select the Obtain an IP address automatically option.
7. Confirm acceptance of the entries with the OK button.
For the communication partner to automatically detect the controller in the entire network or for a point-
to-point connection (PC direct connection), network discovery must be switched on and the UPnP
service must be started on the communication partner (e.g., PC or laptop). No further settings are
necessary on the controller. Settings using the Windows 7 operating system as an example:
1. Switching on network discovery:
a. Press the Windows Start button and select Control Panel.
