EtherNet/IP is the Industrial Ethernet standard of the ODVA (Open DeviceNet Vendor Association). EtherNet/IP is based on Ethernet TCP/IP and UDP/IP; IP stands for Industrial Protocol. Essentially, the CIP (Common Industrial Protocol) used in ControlNet and DeviceNet was ported to Ethernet TCP/IP and UDP/IP.
The IL230x-B905 Fieldbus Coupler Box connects EtherNet/IP with the modular Extension Box modules. A configuration consists of a Coupler Box and up to 120 different Extension Box modules. The Coupler Box automatically detects the connected extensions and allocates the inputs/outputs to the process image words.
The IL230x-B905 EtherNet/IP Coupler Box has a D-coded M12 connection. The IP address is set via a rotary switch (offset from a freely selectable start address). In networks with DHCP (a service for the allocation of the logical IP address to the physical node address [MAC-ID]), the Fieldbus Box obtains its IP address from the DHCP server.
The IP address and other Ethernet parameters are set via two rotary selection switches. Special I/O parameters, for example the type of thermocouple that is used, can be set via KS2000.
The extensive diagnostic functions of the Beckhoff devices allow rapid fault localization. Diagnostic messages are transmitted via Ethernet and collected by the master. LEDs on the module indicate the status of the network connection, the device status, the status of the inputs and outputs and of the power supply.
The EtherNet/IP Coupler Box gathers the I/O data from the Extension Box modules over the interference-free IP-Link optical fibre cable. It detects the connected modules and automatically allocates the input and output data to the process image. The Coupler Box has four digital inputs and four digital outputs; all other signal types are available in the form of an Extension Box.
