Hardware

  • Industrial Controller
  • cDAQ-9189
  • cDAQ-9185

Issue Details

I have an Industrial Controller (IC) connected to my local network, with a cDAQ connected to one of the Ethernet ports of the IC. However, when I try to add the cDAQ in Measurement & Automation Explorer (NI MAX), I receive the following error message:

This device is not reachable.

I cannot see any of the cDAQ modules, and I am unable to change network settings of the chassis.

Solution

The IC's primary Ethernet port is part of a separate Network Identification Controller (NIC) than the other four Ethernet ports. As such, the primary port and the other four ports cannot belong on the same subnet. If the cDAQ is assigned a Static IP on the same subnet as the primary Ethernet port, you will need to change the address to a new subnet on the IC. 

You will also need to set the IC's port connected to the cDAQ to Static to resolve this error.
