New Features and Enhancements
The following feature was added in Release 3.25.
Feature
Description
MRP Fiber SFP Ring break
detection during a single
fiber break
The Rx3i Rack-based IC695PNC001-Bxxx PROFINET Controller and
IC695PNS001-Bxxx/IC695PNS101 PROFINET Scanners can detect a ring break
on a single fiber of the network fiber pair on a fiber SFP. All the supported Fiber
SFP modules use LC connector type fiber optic cables. These cables consist of a
pair of fibers that connect the TX/RX of two fiber SFP modules. The modules
detect a break when the RX signal is no longer detected. In practice, that
means that if only one fiber of the pair is broken, only 1 of the SFP modules
detects that the ring is broken. On the RX3i PNS001-Bxxx, PNS101-Axxx, and
PNC001-Bxxx, when 1 of the fibers of the pair is broken between 2 SFP
modules, the ring indicates that it is open and self-heals. Since only 1 of the SFP
modules detects the lost RX signal, only 1 of them indicates that the Link is
down on the front panel Link LED and in the module’s port Link status bit.
Note: The feature requires the IC695PNC001-Bxxx and IC695PNS001-
Bxxx/IC695PNS101. It is not available on the IC695PNC001-Ax PROFINET
Controller, the IC695PNS001-Axxx PROFINET Scanner, and the
IC200PNS001/IC200PNS002 VersaMax PROFINET Scanners.
