Alignment Errors
Number of frames received that
were not octets in length.
UDINT
Reads the current value.
FCS Errors
Number of frames received that
did not pass the FCS check.
UDINT
Reads the current value.
Single Collisions
Number of frames sent success-
fully with only one collision.
UDINT
Reads the current value.
Multiple Collisions
Number of frames sent success-
fully with two or more collisions.
UDINT
Reads the current value.
SQE Test Errors
Number of times a SQE test error
message was generated.
UDINT
Reads the current value.
Deferred Transmissions
The number of frames for which
the first attempt to send was
delayed because the media was
busy.
UDINT
Reads the current value.
Late Collisions
The number of collisions detected
in packets that were sent after
512 bit times.
UDINT
Reads the current value.
Excessive Collisions
The number of frames that failed
to be sent because of excessive
collisions.
UDINT
Reads the current value.
MAC Transmit Errors
The number of frames that failed
to be sent due to an internal MAC
sublayer transmission error.
UDINT
Reads the current value.
Carrier Sense Errors
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.
UDINT
Reads the current value.
Frame Too Long
The number of frames received
that exceeded the maximum
allowed frame size.
UDINT
Reads the current value.
MAC Receive Errors
The number of frames that could
not be received through the inter-
face due to an internal MAC sub-
layer reception error.
UDINT
Reads the current value.
