Synchronous Analog Input Using RTSI on M Series with Counter Input Task Using LabVIEW with DAQmx

[Chris-NI]

Overview
This example demonstrates how to utilize low level device routing to perform a counter input task on a master device, while simultaneously performing synchronous analog input on multiple M Series PCI devices over RTSI.

Description
X Series devices can utilize channel expansion by placing channels from multiple devices into one task and DAQmx will take care of the synchronization under the hood.

Please note: You must configure your RTSI cable in Measurement & Automation Explorer before running this or you will receive error -89125: No registered trigger lines could be found between the devices in the route.

Requirements

• LabVIEW 2012 (or compatible)
• NI DAQmx 12.0 (or compatible)

Steps to Implement or Execute Code

1.Select channel in Master Physical Channel, Slave Physical Channel and Counter Source controls.

2.Select parameters in the Sample rate control and Sample per Loop control.

3.Run the VI.
