Ethernet Network Ports
The two external Ethernet ports are on the bottom of the module. The illustration below is a
bottom view of IC200PNS001 with its two RJ-45 ports.

SC-Duplex Port
Model IC200PNS001 has two RJ-45 ports, providing 10/100 Mbps copper interfaces. Model
IC200PNS002 has two SC-Duplex ports, providing 100Mbps Multi-Mode fiber interfaces. Each
Ethernet port automatically senses the type of network and adjusts speed and connection
parameters. The PROFINET Scanner requires at least one network be operating at full duplex
for a connection to remain established. The PROFINET protocol may be sent and received over
either or both of the two external ports.
Devices connected to the PROFINET Scanner ports should have Ethernet Autonegotiation
enabled unless the IO-Controller supports configuring the port operation mode. If the
IO-Controller configures the PROFINET Scanner port to a specific setting with autonegotiation
disabled, the device connected to the PROFINET Scanner must be configured for the exact
same setting.
Caution
Both ports on the Ethernet Interface must
not
be connected, directly or indirectly,
to the same device so as to form a circular network unless Media Redundancy is
enabled with one node actively set up as the Media Redundancy Manager.
