8516-BI-PN (Fiber)
Model
8515-BI-PN
has two RJ-45 ports, providing 10/100 Mbps copper interfaces. Model
8516-BI-PN
has two SC-Duplex ports, providing 100Mbps Multimode fiber interfaces. Each
Ethernet port automatically senses the type of network and adjusts speed and connection
parameters. The PNS requires at least one port 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 PNS ports should have Ethernet Autonegotiation enabled unless
the IO-Controller supports configuring the port operation mode. If the IO-Controller configures
the PNS port to a specific setting with autonegotiation disabled, the device connected to the
PNS 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.
