Description
basis
Set for an input when the module either:
• Does not timestamp a transition on the input – The module has Timestamp Latch enabled and a
similar transition has already been timestamped on this input but has not been cleared via the
O.EventAck and O.NewDataAck output tags (see
or
Per point
• Overwrites previously-recorded timestamp data for the input – The module has Timestamp Latch
disabled and multiple transitions occur on the input. In this case, timestamp data from new
transitions are recorded before previously-recorded transitions were cleared from the input via the
O.EventAck and O.NewDataAck output tags (see
This value is cleared if the module is reset.
The offset from the local clock to the system time. This value is useful for detecting steps in time.
Module-wide
This value updates when a PTP update is received.
The time when the PTP message was received to cause the Local Clock Offset to update.
Module-wide
This value is initially zero. The first timestamp occurs when the module synchronizes with the
Grandmaster clock.
Module-wide
The ID number of the Grandmaster clock that the module is synchronized to.
Timestamp value with an input's OFF to ON transition. This tag is a 8 x 1 32-bit array.
Per point
This value is cleared after the data has been acknowledged via the O.EventAck and O.NewData tags.
For more information on clearing timestamp data, see
Timestamp value with an input ON to OFF transition. This tag is a 8 x 1 32-bit array.
Per point
This value is cleared after the data has been acknowledged via the O.EventAck and O.NewData tags.
For more information on clearing timestamp data, see
Running count of the timestamped transitions; this tag increments by one with each new transition that
Module-wide
the module timestamps and rolls over to 1, not 0.
This value is cleared if the module is reset.
Indicates if the module is synchronized with a master clock.
Module-wide
1 = Synchronized
0 = Not synchronized
Description
For the bits selected in the O.NewDataAck tag, this tag selects which edge to acknowledge, On to Off, Off to On or both.
0 = acknowledging an ON to OFF event
1 = acknowledging an OFF to ON event
2 = acknowledging both ON to OFF and OFF to ON events
The O.NewDataAck tag must also be used to acknowledge the event(s).
Allows I.NewData bits and I.Timestamp data updates in the Input tag to function as intended. I.NewData bits are set and
I.Timestamp data updates when a transition occurs and clear only after they are acknowledged via the O.NewDataAck
bit. Typically, the following events occur:
• An event occurs on an input.
• The module sets the I.NewData bit and I.Timestamp data for the input where the event occurred.
• The controller records the new data.
• The controller acknowledges the new data by causing a 0 to 1 transition on the corresponding O.NewDataAck bit.
• The I.NewData bit and I.Timestamp data clears.
• When another event occurs on the input, the sequence begins at the top bullet in this list.
The controller must cause a 0 to 1 transition in this bit to acknowledge new data for an input; in other words, if the
NewDataAck bit is 0 when new data is received, the controller must change this bit to 1 to acknowledge the data. If
NewDataAck bit is 1 when new data is received, the controller must change this bit to 0 and then at least one RPI later to
1 to acknowledge the new data.
When RetrieveByPoint is set, determines point requested for events to be returned. Allows a user to query events in the
sequence they happened by point instead of the overall sequence the events occurred.
Erases all recorded events when transitioned from 0...1.
Changes retrieval mechanism from sequential (when 0) to retrieving events on a per point basis according to value set
in PointToRetrieve field.
