Organizer for that project automatically displays the local DIN rail.
You must configure an RPI rate for the DIN rail. This rate applies to all the
I/O modules you install on the DIN rail.
.
The DriveLogix controller uses to two services to scan I/O: the FlexBus and
the controller itself.
If you have: The fastest possible RPI is:
one rail of digital I/O modules 30 ms
one rail of analog I/O modules 30 ms
one rail of digital and analog I/O modules mixed 30 ms
