Using the Sequence of Events Module Features 5-5
Enable CST Capture
Enable CST Capture instructs the Sequence of Events module to
timestamp specific input points transitions. You can use this feature
to instruct the module to capture the CST when the inputs
transition from:
OFF to ON only
ON to OFF only
or
both OFF to ON and ON to OFF
When Enable CST Capture is enabled for specific points and
transitions occur for those points, the Sequence of Events
module not only captures the CST at the transition
occurrence but also sends input data to the controller.
IMPORTANT
All points on the Sequence of Events module have
Enable Capture CST enabled by default for both
ON to OFF and OFF to ON transitions.
Additionally, you must specify an RPI regardless of
whether you use Enable Capture CST on any input
points. If a change does not occur within the RPI
timeframes, the module will still multicast data at
the rate specified by the RPI.
