Table 68 describes the 5069-IB16F module output tags.

 Name Size Definition Valid Values
Counterxx.Reset BOOL When this bit transitions from 0 to 1, I:Count, and 
I:Rollover are set to zero.
• 0 = Do not reset
• 1 = Reset
Counterxx.RolloverAck BOOL Clears the Rollunder tag in the input tag when it 
transitions from 0 to 1.
0 or 1
Counterxx.Preset DINT • If RolloverAtPreset is set, the counter counts to the 
Preset value and then rolls over to zero.
• If RolloverAtPreset is not set, the counter sets the Done 
bit and continues counting up to Max DINT.
• If C:RolloverAtPreset = 1, then if I:Count ≥ O:Preset, 
I:Count=0., else I:Done bit always = 0. Set I:Rollover 
bit when I:Count transitions from O:Preset – 1 to 0.
• If C:RolloverAtPreset = 0, then if I:Count ≥ O:Preset, 
I:Done = 1, else I:Done = 0. Set I:Rollover bit when 
I:Count transitions from 2,147,483,647 to 0.
0…2,147,483,647
Ptxx.ResetTimestamps BOOL Erases all recorded timestamps for the input channel 
when it transitions from 0 to 1.
• 0 = Timestamps are not erased.
• 1 = Timestamps are erased.
Ptxx.TimestampOffOnNumberAck INT An Off to On timestamp identifier that is written by the 
controller to indicate that the identified timestamp has 
been seen and acted on. 
• When Latching is enabled and the Timestamp Number 
that is received from the controller transitions to the 
most recent timestamp that is produced, the module 
can produce a new timestamp.
• When Latching is disabled and the Timestamp Number 
that is received from the controller transitions to the 
most recent timestamp that is produced, the 
PtxxTimestampOffOn and the 
Ptxx.TimestampOverflowOffOn tags are cleared.
All values.
Ptxx.TimestampOnOffNumberAck INT An On to Off timestamp identifier that is written by the 
controller to indicate that the identified timestamp has 
been seen and acted on. 
• When Latching is enabled and the Timestamp Number 
that is received from the controller transitions to the 
most recent timestamp that is produced, the module 
can produce a new timestamp.
• When Latching is disabled and the Timestamp Number 
that is received from the controller transitions to the 
most recent timestamp that is produced, the 
PtxxTimestampOnOff and the 
Ptxx.TimestampOverflowOnOff tags are cleared.
All values.
