Configuration via Ethernet Overview Interface The controller is equipped with a 10/100 MBit Ethernet interface on connector X1. It can thereby be operated with all common Ethernet components (switches, PCs) and configured via the Plug & Drive Studio software. Hardware address The controller initially has no IP address, but is instead addressed via the printed hardware address (MAC address). This address consists of 6 hexadecimal numbers in form44-AA-E8-xx-xx-xx. The hardware address is unique and unchangeable and is assigned during production. In general, this is only needed during a firmware update. As soon as the boot loader has ended and the actual firmware begins to operate, subsequent communication takes place via the TCP/IP protocol. IP address The controller needs a valid IP address. This can be obtained in the following ways: DHCP: A DHCP server assigns the IP address to the controller (default setting). AutoIP: The controller automatically determines a suitable IP address. The prerequisite here is that the communication partners are in the same physical subnet and also use AutoIP. Static IP address: This is defined by the user. Which method is used depends on the network environment and is defined by the network administrator. The IP address can be determined most easily using the ping tool. To do this, the NetBIOS service must be activated on the PC and the MAC address of the controller must be known. Example If controller with MAC address 44:AA:E8:00:02:9F is to be addressed, the tool is called in a shell or command line using:ping MAC-44AAE800029F 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 is 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 is 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: Press the Windows Start button and select Control Panel. Select Network and Sharing Center. Select Change adapter settings. 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). Select Internet Protocol version 4 (TCP/IPv4) and press the Properties button. Select the Obtain an IP address automatically option. Confirm acceptance of the entries with the OK button. Setting a static IP address If static addresses are to be assigned to the controller and the communication partner, just a few settings need to be performed on the controller and the communication partner. The controller can be assigned a static IP address and network mask (each IPv4) through OD entries. The following entries are relevant in the object dictionary: Index Description 2010h IP configuration, bit mask with the following meaning: Bit 0: A static IP address from object 2011h and the network mask from object 2012h are used. 2011h Static IP address, 4 bytes in hex coding 2012h Static IP subnet mask, 4 bytes in hex coding 2013h Gateway address 2014h Active IP address, 4 bytes in hex coding 2015h Active IP subnet mask, 4 bytes in hex coding 2016h Currently used gateway address 200Fh MAC address Note: You must save the objects 2010h…2013h (category: Ethernet) after making changes (see the chapter Saving objects) by writing the value "65766173h" in 1010h:0Ch. The changes are not taken over until after the controller has been restarted. Notes: If DHCP was activated and Auto-IP is not active, the controller uses the set static IP address if no address could be assigned via DHCP (e.g., because the DHCP service is temporarily unavailable). If both objects 2010h and 2011h are set to the value "0", an incorrect configuration is assumed and DHCP and Auto-IP are switched on. If bit 0 is set in object 2010h, the static IP address is used. DHCP is not used in this case. If DHCP and Auto-IP are activated simultaneously, DHCP is used first to try and obtain an address. If this does not function, Auto-IP is executed. If only DHCP is switched on and an IP address assignment did not function, an attempt is made independent of bit 0 to connect using the entered static IP address. A static IP address is also assigned to the communication partner. Settings using the Windows 7 operating system as an example: Press the Windows Start button and select Control Panel. Select Network and Sharing Center. Select Change adapter settings. A list of the available network adapters is displayed. Open the properties on the adapter with which the controller is connected (e.g., right-mouse click and select Properties). Select Internet Protocol version 4 (TCP/IPv4) and press the Properties button. Select the Use the following IP address: option and enter the desired IP address and network mask in the IP address field. Confirm acceptance of the entries with the OK button. Establishing network connection Establish a physical connection between controller and communication partner using a standard Ethernet cable. If static IP addresses were assigned to the controller and the communication partner, they can communicate directly. If you have your own DHCP server and wish to ascertain the IP address, this can be accomplished most easily with the ping tool. To do this, the NetBIOS service must be activated on the PC and the MAC address of the controller must be known.
