Counters
The FRAMES counter gives the total number of completed remote, data, overload, and
active error frames.
The OVLD counter gives the total number of completed overload frames and their
percentage of the total number of frames.
The ERR counter gives the total number of completed active error frames and their
percentage of the total number of frames.
The UTIL (bus load) indicator measures the percentage of time the bus is active. The
calculation is done on 330 ms periods, approximately every 400 ms.
Example: If a data frame contains an active error flag, both the FRAMES counter and the
ERR counter will be incremented. If a data frame contains an error that is not an active
error it is considered a partial frame and no counters are incremented.
