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.
