Name Data Type Tag Definition Module Definition
LatchTimestamps BOOL Latch Timestamps—Latches a CIP Sync timestamp for a COS transition:
• When an initial timestamp is latched, timestamps for subsequent COS transitions are
dropped.
• Once a latched timestamp is acknowledged via the corresponding bit in the
Pt[x].NewDataOffOnAck or Pt[x].NewDataOnOffAck tag, the timestamp is overridden
upon the next COS transition.
Requires COS to be enabled via the Pt[x].COSOffOnEn or Pt[x].COSOnOff tags. For more
information, see
page 87 .
0 = Timestamps are overridden with each successive COS transition.
1 = Timestamps are latched until acknowledged.
Connection = Data
Input Data = Data or Timestamp Data
or
Connection = Data with Event
Input Data = Timestamp Data
FilterOffOn INT Filter Time Off to On—Defines how long an Off to On input transition must remain in the
On state before the module considers the transition valid. For more information, see
page 90 .
Valid filter time = 0…30,000 μs
Connection = Data
Input Data = Data or Timestamp Data
or
Connection = Data with Event
Input Data = Timestamp Data
FilterOnOff INT Filter Time On to Off—Defines how long an On to Off input transition must remain in the
Off state before the module considers the transition valid. For more information, see
page 90 .
Valid filter time = 0…30,000 μs
Connection = Data
Input Data = Data or Timestamp Data
or
Connection = Data with Event
Input Data = Timestamp Data
Pt[x].FilterEn BOOL Filter—If enabled for a point, input transitions must remain in the new state for a
configured length of time before the module considers the transition valid. For more
information, see
page 90 .
0 = Filtering is disabled.
1 = Filtering is enabled.
Connection = Data
Input Data = Data or Timestamp Data
or
Connection = Data with Event
Input Data = Timestamp Data
Pt[x].COSOffOnEn BOOL Change of State Off to On—If enabled for a point, an Off to On transition triggers a
timestamp recording and sends a COS message on the backplane. For more information, see
page 52 .
0 = COS data is not produced upon an Off to On transition.
1 = COS data is produced upon an Off to On transition.
Connection = Data
Input Data = Data or Timestamp Data
or
Connection = Data with Event
Input Data = Timestamp Data
Pt[x].COSOnOffEn BOOL Change of State On to Off—If enabled for a point, an On to Off transition triggers a
timestamp recording and sends a COS message on the backplane. For more information, see
page 52 .
0 = COS data is not produced upon an On to Off transition.
1 = COS data is produced upon an On to Off transition.
Connection = Data
Input Data = Data or Timestamp Data
or
Connection = Data with Event
Input Data = Timestamp Data
Table 44 - 1756-IB16IF Module Input Tags
Name Data Type Tag Definition Module Definition
Fault DINT Fault Status—Indicates whether a point is faulted. If communication to the input
module is lost, then all 32 bits will be set. For more information, see
page 106 .
0 = No fault
1 = Fault
Connection = Data or Listen Only
Input Data = Data or Timestamp Data
or
Connection = Data with Event or Listen
Only with Event
Input Data = Timestamp Data
LocalClockOffset DINT Local Clock Offset—Indicates the offset in microseconds between the current CST and
the CIP Sync value when a valid CIP Sync time is available. Connection = Data, Data with Event,
Listen Only, or Listen Only with Event
Input Data = Timestamp Data
OffsetTimestamp DINT Timestamp Offset—Indicates when the CIP Sync time was last updated. The timestamp
is in CIP Sync time. Connection = Data, Data with Event,
Listen Only, or Listen Only with Event
Input Data = Timestamp Data
GrandMasterClockID DINT Grandmaster Clock ID—Indicates the ID of the CIP Sync Grandmaster to which the
module is synced. Connection = Data, Data with Event,
Listen Only, or Listen Only with Event
Input Data = Timestamp Data
