Serial DIO versus Parallel DIO Modules
- Software-timed and hardware-timed digital input/output tasks
Software-timed and hardware-timed digital input/output tasks
Counter/timer tasks (can be used in up to two slots)
Accessing PFI signal tasks (can be used in up to two slots)
Filter digital input signals
You cannot use parallel and serial modules together on the same hardware-timed task.
You cannot use serial modules for triggering.
You cannot do both static and timed tasks at the same time on a single serial module.
You can only do hardware timing in one direction at a time on a serial bidirectional module.
To determine the capability of digital modules supported by the controller, refer to the Software Support for CompactRIO, CompactDAQ, Single-Board RIO, R Series, and EtherCAT document.
