Accuracy is the estimated maximum time error at present in the RTC, considering the quality information imbedded in the
received time signal. The value 999,999,999 indicates that the magnitude of the estimated error is one second or more, or
that 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 time
being received via PTP and that being received via IRIG-B. A positive value indicates that PTP time is fast compared to
IRIG-B time.
6.2.15 DIRECT INPUTS
PATH: ACTUAL VALUES  STATUS  DIRECT INPUTS
The AVERAGE MSG RETURN TIME is the time taken for direct output messages to return to the sender in a direct input/output
ring configuration (this value is not applicable for non-ring configurations). This is a rolling average calculated for the last
ten 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 not
make the trip around the communications ring. The
CRC FAIL COUNT values (one per communications channel) count the
direct output messages that have been received but fail the CRC check. High values for either of these counts may indicate
on a problem with wiring, the communication channel, or one or more relays. The
UNRETURNED MSG COUNT and CRC FAIL
COUNT 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.
