IL230x-B903 | Fieldbus Box modules for PROFINET

PROFINET is the open Industrial Ethernet standard of the PNO (PROFIBUS user organisation). Internationally established IT standards such as TCP/IP are used for communication. PROFINET IO describes data exchange between controllers and field devices. It can be used in standard Ethernet networks and networked via commercially available switches.

The IL230x-B903 Fieldbus Coupler Box connects PROFINET with the modular Extension Box modules. A configuration consists of a Coupler Box and up to 120 different Extension Box modules. The Coupler Box detects automatically the connected extensions and allocates the inputs/outputs to the process image words.

The PROFINET Fieldbus Box supports 10 Mbit/s and 100 Mbit/s PROFINET. The PROFINET connection is established via a D-coded M12 connector. The IP address is set via a rotary switch (offset to 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.

Configuration

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.

Diagnostics

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.

Coupler Box

The PROFINET 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.
