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.

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.
