Interrupt Response Times
Appendix C
Pulse Output Startup Time
The startup time is the time it takes between the execution of a pulse output instruction and the actual output of
pulses from the output terminals. The startup time depends on the pulse output instruction being used and the
selected operation.
Pulse Output Change Response Time
In some cases, another pulse output instruction can be executed during a pulse output operation to change the
settings or the operation itself. The change response time is the time it takes between the execution of another
pulse output instruction and the actual change in the pulse output at the output terminals.
