Basic function principles

EL6652(-0000) EtherNet/IP Master

The EL6652 EtherNet/IP-Master Terminal has a switched 2-port Ethernet connection and can thus be operated in a line with further Ethernet/IP nodes. The process data are configured by an EtherCAT master, allowing different process data and sizes. The EL6652 supports both multicast and unicast connections. Up to 16 simple EtherNet/IP-Slave devices can be connected via one generic node. The EL6652 is optionally also available as a slave version.

Configuration

The configuration is carried out in several steps. The terminal must be contained in the EtherCAT master (e.g. TwinCAT) as EL6652 in the EtherCAT tree. Furthermore an additional device must be created in order to provide this terminal with the parameters and with configuration data (see Configuration and see EDS file).

EL6652-0010 EtherNet/IP Slave

The EtherNet/IP Slave terminal enables the exchange of data with an EtherNet/IP scanner or a master. Both Multicast and Unicast are supported. In addition, the terminal can behave like two EtherNet/IP slave devices. The second slave is a virtual slave. This enables you to connect two masters together or one master with two slaves and, for example, to transport more data or to operate with different polling times on the master. The maximum process data in both directions is 1 kbyte.

The terminal is an EtherCAT slave device and is configured via the EtherCAT master. The IP settings as well as the number and types of data items are defined here. The terminal behaves on the EtherNet/IP side as a slave device in the EtherNet/IP network. No further configuration is necessary via the EtherNet/IP master. A connection can only be successfully established if the EtherCAT master is running and in data exchange mode; only then can the EtherNet/IP master also establish a connection.

Configuration

The configuration takes place in several steps. The terminal must be contained in the EtherCAT master (e.g. TwinCAT) as EL6652-0010 in the EtherCAT tree. Furthermore an additional device must be created in order to provide this terminal with the parameters and with configuration data (see Configuration and Parameters). Once this is completed and the EtherCAT master is in data exchange mode, the configuration takes place in the EtherNet/IP Master/Scanner.

EtherCAT XML device description and configuration files

We recommend downloading the latest EtherCAT Device Description from the download area on the Beckhoff website and installing it according to the installation instructions.

The process image is freely configurable. In this way it is possible to reduce the process data for internal application to a minimum.
