Stores the rate (maximum value) of receiving error frame at the IN-side of own
station. (Unit: %)
The accumulation of errors is cleared when Clear IN-side transmission error
counter (SB0007) is turned ON.
Stores the rate (present value) of receiving error frame at the IN-side of own
station. (Unit: %)
The accumulation of errors is cleared when Clear IN-side transmission error
counter (SB0007) is turned ON.
