Ethernet Communication Modules in the Local Rack

Monitor diagnostics for Ethernet Communication Modules in the Local Rack:

Status of...	Module [1]	User Application [2]	Control Expert [3]	Rack Viewer [5]	Ethernet Management Tool [6]
BMENOC0301/11 Ethernet backplane connection broken	BMENOC0301/11 active LED
BMENOC0301/11 reset	BMENOC0301/11 LED	BMENOC0301/11 health bit (in CPU system word) I/O scanner connection status	DTM online diagnostic inoperable	yes	yes
BMENOC0301/11 inoperable	BMENOC0301/11 LED	BMENOC0301/11 health bit (in CPU system word) I/O scanner connection status	DTM online diagnostic inoperable	yes	yes
Refer to the module LED to detect a pulled cable, an inoperable module, or reset module (LED on, off, or flashing to display status or detected error pattern). Refer to your application to detect the module status (link Ethernet port, EIP scanner status, DDDT, system words). Use the DTM browser in Control Expert to detect whether a BMENOC0301/11 is inoperable or has been reset. Not applicable. Use the FactoryCast rack viewer to detect if a BMENOC0301/11 is inoperable or has been reset. Use ConneXium Network Manager, HiVision, or other Ethernet network management tool to detect if a BMENOC0301/11 is inoperable or has been reset.

Ethernet RIO Network

NOTICE

UNINTENTIONAL EQUIPMENT BEHAVIOR

Confirm that each module has a unique IP address. Duplicate IP addresses can cause unpredictable module/network behavior.

Failure to follow these instructions can result in equipment damage.

Monitor diagnostics for the Ethernet RIO network:

Status of...	Module [1]	User Application [2]	Rack Viewer [5]	Ethernet Management Tool [6]
duplicate IP address in CPU or BMXCRA312•0	BMEP58•0•0 LED BM•CRA312•0 LED
CPU (single) cable pulled out	BMEP58•0•0 active LED	CPU status byte CPU DDDT	yes	yes
BM•CRA312•0 (single) cable pulled out	BM•CRA312•0 ACT LED	drop connection status (in CRA DDDT)		yes
BMENOS0300 diagnostic	ACT LED		web page	yes
DRS powered off	DRS power LED	DATA_EXCH block: monitor DRS (ports 5 and 6)		yes
DRS cable pulled out	DRS ACT LED	DATA_EXCH block: monitor DRS (ports 5 and 6)	DRS web	yes
main ring cable broken		EIO system bit (part of CPU DDT)	DRS web (only if cable on DRS port is broken)
single ring cable broken		DATA_EXCH block: monitor DRS (ports 5 and 6)	DRS web
RIO traffic too slow (due to bad configuration or cabling)		DATA_EXCH block: monitor DRS (port 5 and 6) Also possible via CRA DDDT
DIO traffic too slow (generate too much traffic)		DATA_EXCH block: monitor DRS (port 5 and 6)	DRS web	MIB
Refer to the module LED to detect a pulled cable or a powered-off device (LED on, off, or flashing to display status or detected error pattern). Refer to your application (via system word, CPU DDDT, or DATA_EXCH block) to detect a pulled cable, a powered-off device, a break in the main ring or sub-ring, or slow network traffic. Not applicable. Use the DRS web pages to detect a pulled cable or a break in the main ring. Use the rack viewer to detect if a CPU is inoperable or has been reset. Use ConneXium Network Manager, HiVision, or other Ethernet network management tool to detect a pulled cable in a CPU, BM•CRA312•0 X80 EIO adapter module, or DRS. Also use this tool to detect DRS power state and slow DIO traffic.

Ethernet RIO Drops

Monitor diagnostics for Ethernet RIO drops:

Status of...	Module [1]	User Application [2]	Rack Viewer [5]	ConneXium Network Manager [6]
BM•CRA312•0 powered off or disconnected	BM•CRA312•0 LED	drop connection status (in CPU DDDT) detected drop error status (in CPU DDDT)		yes
BM•CRA312•0 not configured	BM•CRA312•0 LED CPU LED	drop connection status (in CPU DDDT) detected drop error status (in CPU DDDT)		yes (It does not appear on the screen.)
extended rack inoperable (detected fault in BM• XBE 100 00 or cable)	module PWR LED	remote module health bits (in device DDDT)	yes
Refer to the module LED to detect a powered-off, disconnected or unconfigured BM•CRA312•0 X80 EIO adapter module or to detect an inoperable extended rack (LED on, off, or flashing to display status or detected error pattern). Refer to your application (via system word) to detect a powered-off, disconnected or unconfigured BM•CRA312•0 X80 EIO adapter module or to detect an inoperable extended rack. Not applicable. Not applicable. Use the FactoryCast rack viewer to detect a powered-off, disconnected or unconfigured BM• XBE 100 00 module. Use ConneXium Network Manager, HiVision, or other Ethernet network management tool to detect a a powered-off, disconnected or unconfigured BM•CRA312•0 X80 EIO adapter module.
