• If the trigger input changes from OFF to ON more than once during the NX bus I/O refresh cycle,
the High-speed Analog Input Units record the DC time at the first change.

Identifying the Analog Input Value When Trigger Input Was
Turned ON
The High-speed Analog Input Units have a library of the Sysmac Library prepared to identify and read
an analog input value at the time when trigger input was turned ON. Refer to the
Sysmac Library
User’s Manual for High-speed Analog Inspection Library (Cat. No. W607) for how to read values using
the library.
This section describes how to identify the analog input value when trigger Input was turned ON, with-
out using the library.
It provides a timing chart example and then the identification method to describe how to identify the
Ch1 Analog Input Value when the Ch1 trigger input was turned ON under the following conditions.
