6-8 L60 Line Phase Comparison System GE Multilin6.2 STATUS 6 ACTUAL VALUES6Accuracy is the estimated maximum time error at present in the RTC, considering the quality information imbedded in thereceived time signal. The value 999,999,999 indicates that the magnitude of the estimated error is one second or more, orthat the error cannot be estimated.PORT 1…3 PTP STATE is the present state of the port’s PTP clock. The PTP clock state is:• DISABLED is the port’s function setting is Disabled,• NO SIGNAL if enabled but no signal from an active master has been found and selected,• CALIBRATING if an active master has been selected but lock is not at present established,• SYNCH’D (NO PDELAY) if the port is synchronized, but the peer delay mechanism is non-operational, and• SYNCHRONIZED if synchronized.PTP-— IRIG-B DELTA is the time difference, measured in nanoseconds, between the fractional seconds portion of the timebeing received via PTP and that being received via IRIG-B. A positive value indicates that PTP time is fast compared toIRIG-B time.6.2.15 DIRECT INPUTSPATH: ACTUAL VALUES STATUS DIRECT INPUTSThe AVERAGE MSG RETURN TIME is the time taken for direct output messages to return to the sender in a direct input/outputring configuration (this value is not applicable for non-ring configurations). This is a rolling average calculated for the lastten messages. There are two return times for dual-channel communications modules.The UNRETURNED MSG COUNT values (one per communications channel) count the direct output messages that do notmake the trip around the communications ring. The CRC FAIL COUNT values (one per communications channel) count thedirect output messages that have been received but fail the CRC check. High values for either of these counts may indicateon a problem with wiring, the communication channel, or one or more relays. The UNRETURNED MSG COUNT and CRC FAILCOUNT values can be cleared using the CLEAR DIRECT I/O COUNTERS command.The DIRECT INPUT 1 to DIRECT INPUT (32) values represent the state of each direct input.
