Specific Features of the 1732E-IB8M8SOER Sequence of Events Input Module Chapter 8
• Scenario #3 – The input turns ON but turns OFF before 2 ms (length of
the input filter setting) elapses. In this case, the module continues to scan
the input every millisecond until the 1 ms counter decrements to zero. The
input never remains ON for at least 2 consecutive ms intervals, the third
ON sampled 1 ms interval. In this case, the module considers the
transition invalid and drops the data timestamped at the original
transition.
Use the Configuration tab in RSLogix 5000 software to configure Input Filters,
as shown in the example below.
Sync to Master The Sync to Master feature in the 1732E-IB8M8SOER module indicates
whether the module should have synchronization with a master clock. When
enabled, the module remains in, or transitions to, the configuring state until

Input turns OFF before
2 ms have elapsed.
In none of these time periods is the input
ON for at least 2 consecutive ms intervals.
After 7 ms, the module drops the data
recorded at the original transition. If an RPI
occurs during this 7 ms, the module sends
the controller its current valid input data; the
data that is sent does not include data from
the transition describes in this graphic
because the timestamp has not been
validated.
The next time the input turns ON, the
module records the transition as
timestamp #1, with the timestamp of the
new input transition.
Input turns ON;
timestamp #1 recorded
Type the filter times or use the
drop down menu to select the
Input Filter Time.
The Input Filter Time range is 0,
1, 2, 4, 8 or 16 ms.
