Three Siemens fire-fighting hosts fc18 are equipped with can optical transceiver for optical fiber redundant ring network networking test

Project background ：

1、 Three Siemens fire engines FC18 Form an optical fiber redundant ring network ;

2、 When a single equipment or a section of line fails , It will not affect the normal operation of other devices in the network .

Networking and test scheme 025-68250795：

1、 Siemens fire host FC18 adopt CAN The interface is connected to a redundant loop network CAN Optical transceiver LCAN-FOBR;

2、 Three CAN The optical transceiver is connected together through optical fiber , Connected into an optical fiber ring network ;

3、 All three hosts are online normally , The three hosts are linked normally ;

4、 Pull out any one CAN Optical fiber of one optical port of optical transceiver , All three hosts are online normally , No alarm , No hosts lost .
