DIO-32DM2-PE
Generating function
Generating control
DIO-32DM2-PE can output (generate) pattern data at fixed intervals using a generating clock. The
table below lists the generating clock, generating start trigger, and generating stop trigger factors.

- The product outputs the first pattern data at the falling edge of the generating clock signal after
input of the generating start trigger. From then on, the product outputs pattern data in
synchronization with the generating clock signal.
- The product stops pattern data output upon input of the generating stop trigger.
