Issue Details

We are using an HBM power analyzer and its ESI file contains more than 400 objects. However, we can only see about 150 of them. As a result the slave does not work properly and cannot be transitioned to Active mode.

Solution

The issue is in the Host - Get Third Party ECAT IOVs.vi.

After 143 objects, the Variable Object node replaces the IP address of the host with "localhost" in the reference. This causes the node to throw an error

To be able to workaround this, you will first need to install the source code here and go to the Host - Get Third Party ECAT IOVs.vi from the Scan Engine.lvproj located here ...\niveristand-scan-engine-ethercat-custom-device-main\niveristand-scan-engine-ethercat-custom-device-main\Custom Device Source. The solution is to manually replace "localhost" with the actual IP Address, as shown below

After that, rebuild the Get HW Config.exe

Replace the old executable located here C:\Users\Public\Documents\National Instruments\NI VeriStand 2023\Custom Devices\Scan Engine\Application with your new build. Now you should be able to find all the channels of your slave device.
