Using the Module
Introduction
This chapter describes how to use the 1732E EtherNet/IP ArmorBlock
Supporting Sequence of Events module. The chapter contains the following
main sections:.
Overview
The 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.
