Chapter 10 Use the Sequence of Events Input and Scheduled Output Modules
Overview The 1732E-IB8M8SOER module can be configured to timestamp two
transitions per input, one in each direction (OFF to ON and ON to OFF).
When specific points that are Timestamp Capture-enabled transition (for
example, input 1 is configured so that Timestamp Capture is enabled for OFF to
ON transitions and the input turns ON), the module timestamps the transition
with the current system time value on the network. The module produces data
for the owner-controller the RPI after the input filter criteria have been met and
at subsequent RPIs.
For the 1732E-OB8M8SR module, timestamping can be used in conjunction
with the scheduled outputs feature so that after input data changes state and a
timestamp occurs, an output point will actuate at some configured time in the
future. You can schedule outputs up to 16 seconds into the future.
When you use timestamping of inputs and scheduled outputs, you must:
• choose a Communication Format for each input and output module that
allows timestamping. See Communication Format for more information.
• disable Change of State for all input points on the input module except the
point being timestamped.
