Connecting to a PROFINET Network
The RXi Controller provides two RJ-45 ports for PROFINET network connections. They can
also be used for general Ethernet communications on a 10BaseT, 100BaseTX, or
1000BaseT IEEE 802.3 network.
PROFINET IO can be connected to either of the two PROFINET ports. Use of Media
Redundancy Protocol (MRP) requires both PROFINET ports. If MRP is not used, the
PROFINET IO can be connected to either port.
PROFINET Media
10BaseT: uses a twisted pair cable of up to 100 meters in length between a node and
another node, switch, hub, or repeater. 10Mbs can be used for general Ethernet traffic, but
not for PROFINET communications.
100BaseTX: uses a cable of up to 100 meters in length between a node and another node,
switch, hub, or repeater. The cable should be data grade Category 5e or better shielded
twisted pair (STP).
1000BaseT: uses a cable of up to 100 meters in length between a node and another node,
switch, hub, or repeater. The cable should be data grade Category 5e or better STP.
The operation of the Ethernet port LED indicators, ACTIVITY and LINK, is described in
Section 1.3.3 PROFINET and GbE Port LEDs.

Note:
For sample PROFINET network topologies, refer to section 9.2 PROFINET
Networks for PACSystems.
Do not connect both ports on the RXi to the same device,
either directly or indirectly, unless Media Redundancy is
enabled in the PROFINET interface configuration.
If Media Redundancy will be used, do not close the network
ring until a Media Redundancy configuration that contains a
Media Redundancy Manager (MRM) node has been
downloaded to the RXi. If an MRM is not present, packets
can continuously cycle on the network, using up significant
network bandwidth.
