Error -201483 When Running Multiple Simulated TSN Devices in a Single DAQmx Task

Issue Details

I am running several simulated TSN devices (cDAQ-9185 and cDAQ-9189) and trying to include them in a single task in LabVIEW using DAQmx VIs. However, whenever I try to run the task with multiple chassis, I get the following:

Error -201483:

The selected master for the configured multi-device task is not able to export signals. Make sure that the first channel in the task is from a device on a chassis that has an NI 9469 capable of exporting signals to the slave devices. If you have any delta-sigma modules in your task, at least one must be in the master chassis. For time-based synchronization, ensure all the chassis in the task are in the same synchronization network.

I've verified the setup and configurations, and each chassis works individually, but combining them causes the issue.

Is using multiple TSN chassis in a single DAQmx task impossible, or am I missing something in the configuration?

Solution

The TSN devices must be physically connected to each other using an Ethernet cable for synchronization to occur when working with multiple chassis.

When running the acquisition with simulated devices, there is no actual connection between them, which leads to the error observed when attempting to include more than one chassis in a single task.

Additional Information

1. For Real Hardware Setup:
   • Ensure all TSN-enabled devices are connected via Ethernet cables in the correct topology to enable synchronization. Double-check the network configuration and ensure the devices are using compatible firmware versions.
2. For Simulated Devices:
   • Run separate tasks for each chassis instead of combining them into one.
   • Use manual synchronization techniques (e.g., software triggers) to approximate simulation timing alignment.
   • Consider leveraging other testing tools to validate multi-chassis setups if real hardware is unavailable.
