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.
