• 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.

Slave Terminal Operation
The following describes the trigger input operation of the High-speed Analog Input Units in an
EtherCAT Slave Terminal connected to the built-in EtherCAT port.
• The High-speed Analog Input Units record input changed times for each trigger input bit. The
Units record the DC times when status changes of the input terminals reach the internal circuits
after the ON response time elapses.
If the input filter is used for the Input Filter Setting, the time set in the Input Filter Setting is added
to the ON response time.
• The EtherCAT Coupler Unit reads input values and input changed times from the High-speed An-
alog Input Units at I/O refreshing.
The EtherCAT Coupler Unit reads input values at I/O refreshing, instead of the input values at
the point of time when the input changed times are recorded.
