Number of errored seconds. An errored second is one with at least one CRC anomaly (see perfDataCV below) and/or at least one LOSW defect (see perfDataLOSWS below). In the 15 minute history, this register ranges from 0 to 900. In the 24 hour history, it ranges from 0 to 86400 (=24*3600) seconds). This register is inhibited, that is not counted while UAS is counting. Due to variations in the communication delay, sampling periods can slightly deviate from their ideal length of 15 minutes or 24 hours. This can cause the register to show values somewhat above 900 (86400 resp.) seconds.
