CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
Description
Media counters for the Ether-
Net/IP Unit.
Number of frames received that
were not octets in length.
Number of frames received that
did not pass the FCS check.
Number of frames sent success-
fully with only one collision.
Number of frames sent success-
fully with two or more collisions.
Number of times a SQE test error
message was generated.
The number of frames for which
the first attempt to send was
delayed because the media was
busy.
The number of collisions detected
in packets that were sent after
512 bit times.
The number of frames that failed
to be sent because of excessive
collisions.
The number of frames that failed
to be sent due to an internal MAC
sublayer transmission error.
The number of times the carrier
sense condition was lost or the
number of times an assertion did
not occur when an attempt was
made to send the frame.
The number of frames received
that exceeded the maximum
allowed frame size.
The number of frames that could
not be received through the inter-
face due to an internal MAC sub-
layer reception error.
Counter for the EtherNet/IP Unit.
Auto Nego for Ethernet communi-
cations that specifies full duplex.
Gives the set value of the Ether-
net baud rate.
FALSE: The link is down.
TRUE: The link is up.
FALSE: Half duplex
TRUE: Full duplex
00 hex: Auto-negotiation is in progress.
01 hex: Auto-negotiation and speed detection failed.
02 hex: Auto-negotiation failed, but speed detection succeeded.
03 hex: Speed and duplex mode negotiation succeeded.
04 hex: Auto-negotiation was not attempted.
Always FALSE: Changes can be applied automatically.
