Hardware Design
4.2.4 Ethernet Based Networks (Copper)
The industrial networks, that use Ethernet for communication, share the same hardware design.
However, the firmware downloaded to the brick is different depending on network. Physically
they use the same set of pins in a similar way. At the moment Anybus CompactCom B40 Modbus
Serial is available for the following Ethernet based networks: EtherNet/IP and PROFINET IRT.
The brick supports dual network ports, signal group A should be connected to the left port (port
1) and signal group B to the right port (port 2) on the connector board, looking at the front, see
Connector Board for Copper Based Ethernet, p. 35

4.2.5 Ethernet Fiber Optic Networks
Ethernet fiber optic networks use more or less the same pins as copper based Ethernet networks.
The brick supports PROFINET fiber optic network (PROFINET IRT).
The brick supports dual network ports, signal group A is be connected to the left port (port 1)
and signal group B to the right port (port 2)on the connector board, looking at the front, see
Fiber Optic Conenctor LÄNK!!.
If the Anybus CompactCom B40 connector board is not to be used, please study the design
requirements for the Rx and SD channels, see
Channel Design Requirements, p.
preferred in order to minimize EMC disturbance.
