GFK-2571R May 2021
Installation 34
CAUTION
• If an RX3i PROFINET Controller is extracted from a powered RX3i backplane, it loses
power immediately, which may result in data loss. Do not remove or insert the device
while downloading hardware configuration to the system.
• When the module is plugged back into a powered backplane, the PNC001 module
restores data from the internal non-volatile memory. If, however, the RX3i CPU has
configuration data for the PROFINET Controller, it re-delivers the data to the PNC001
module, superseding parameters previously stored in non-volatile PNC001 memory.
Fault Notifications
Removing a PROFINET Controller causes a Loss of IOC fault in the RX3i CPU’s I/O Fault Table
and inserting a PROFINET Controller causes an Addition of IOC fault in the I/O Fault Table.
2.7 Ethernet Port Connections
Each port on an RX3i PROFINET Controller operates independently. This is true for all ports
on the PNC001 module and for ports assigned to embedded PROFINET Controllers. In this
way, devices that operate at different speeds and/or duplex modes may be attached to a
compatible port. Each port automatically detects the attached cable and functions properly
with either straight-through or crossover cables.
Note:
All PROFINET Controller ports operate in auto-negotiate mode only. All PROFINET devices
and switches that are connected to the PROFINET Controller should be configured to use
auto-negotiation.

2.7.1 PROFINET Network Connections
Connections to the PROFINET Controller can be made using standard cables. The PROFINET
Controller can be connected to only one PROFINET network. However, different devices on
the same LAN can be connected via more than one port.
Note : Shielded cable is required for 1 Gbps operation
