The 68-pin motion I/O connector provides all the signals for four axes of
closed-loop motion control, including encoder feedback, limit and home
inputs, breakpoint outputs, trigger inputs, digital-to-analog (DAC), and
analog-to-digital (ADC) converter signals. Refer to Chapter 5, Signal
Connections, for details about the signals in the motion I/O connector.
The 68-pin digital I/O connector provides 32 bits of user-configurable
digital I/O. Refer to Chapter 5, Signal Connections, for details about the
signals in the digital I/O connector.
The PCI-7340 RTSI connector provides up to eight triggers to facilitate
synchronization between multiple National Instruments products. The
PXI-7340 RTSI-enabled connection provides up to eight triggers and one
PXI star trigger to facilitate synchronization between multiple National
Instruments PXI-enabled products. Typical applications of the RTSI bus
include triggering an image acquisition or DAQ measurement based on
motion events, or capturing current motion positions based on events
external to the motion controller. You also can use the RTSI bus for general
hardware-based communication between RTSI devices.
The RTSI bus also can be used for general-purpose I/O. Refer to Chapter 5,
Signal Connections, for details about RTSI connector signals.
