NewData – New data, has been detected upon that input and an unread event is queued for that point.
EventOv – Set whenever the module begins to lose events for that input point. Events may be lost when
new events are either ignored or overwriting existing events which have yet to be acknowledged.
EventNumber – Running count of events which increments by one each new event. Allows the controller
to check for a new events easily by comparing this number to the last retrieved event. If the
EventNumber reaches its maximum value and rolls over it will roll-over to 1, not 0.
In Time Stamp – Timestamp corresponding to when an event was recorded at one of the modules
inputs.
Local Clock Offset – The offset from the local clock to the system time. This value is useful for detecting
steps in time. This value will update when a PTP update is received.
Where: Offset Time Stamp – The time when the PTP message was received that caused the Local Clock Offset
to update. This value will initially be zero and the first timestamp will occur when the module
synchronizes with the master clock.
Grandmaster Clock ID – The ID number of the Grandmaster clock the module is synchronized to.
Synced to Master – 1 indicates the module is synchronized with a master clock. 0 indicates it is not.
In order to acknowledge receipt of an event the user must transition the corresponding NewDataAck bit
from 0 to 1 and set the EventAck to indicate whether to acknowledge the Off-On or On-Off transistion for
the input. The NewDataAck bits and EventAck are in consumed assembly instance159.
Time stamps will be zero at power-up and after a time stamp is acknowledged. The time base and epoch
of the timestamps are determined by the grand-master clock of the system.
All data listed in this assembly is in Little Endian format, LSB first, in increasing byte order to MSByte last.
