Rockwell Automation 1732E-IB16M12SOEDR EtherNet/IP ArmorBlock supporting Sequence of Events - Manual (Page 51)

Publication 1732E-UM002A-EN-P - March 2010
Module Features 43
Operational Mode
The module operates only in Per Point Mode:
Per Point Mode
The module produces timestamps for up to 2 input transitions per input, one
for OFF to ON transitions and another for ON to OFF transitions; these
timestamps can occur simultaneously on separate inputs.
Timestamp Capture
Timestamp Capture instructs the module to timestamp specific input point
transitions. You can use this feature to instruct the module to capture the
timestamp when the inputs transition from:
• OFF to ON only
• ON to OFF only or
• both OFF to ON and ON to OFF
When Timestamp Capture is enabled for specific points and transitions occur
for those points, the module not only captures the timestamp at the transition
occurrence but also sends input data to the controller.
IMPORTANT
All points on the module have Enable Timestamp Capture
enabled by default for both ON to OFF and OFF to ON
transitions.
Additionally, you must specify an RPI regardless of whether you
use Timestamp Capture on any input points. If a change does
not occur within the RPI timeframes, the module will still
produce data at the rate specified by the RPI.
