Direct Inputs; Direct Devices Status - GE D30 series Instruction Manual

6.2 STATUS
is the time difference, measured in nanoseconds, between the fractional seconds portion of the time
PTP-— IRIG-B DELTA
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 value 999,999,999 indicates that the difference is not being measured due to one or both of the time sig-
nals being absent or disabled.

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
