Error -732159 on Auto-Detect Modules in Scan Engine and EtherCAT Custom Device

Issue Details

I am using the Scan Engine and EtherCAT Custom Device in VeriStand. When I try to detect the modules by clicking the Auto-Detect Modules button, I get the following error:

Error -732159 occurred at SEECD System Explorer.lvlib:Confirm Hardware Found.vi

Solution

This error may occur if the EtherCAT chassis does not have any modules physically installed. First, ensure that the EtherCAT modules are properly installed in the chassis.

If modules are installed and the error persists, verify that the version of the Scan Engine and EtherCAT Custom Device is at least 23.3.

This issue is known to occur with couple of versions of the Custom Device when used with VeriStand (2023-2025). To avoid this issue, the recommended solution is to use 26.0.0 or newer of the Custom Device. You can do this by either:

• Upgrading the VeriStand Custom Devices add-on to latest version.
• Downloading the latest version of the Custom Device from GitHub.
• If the error persists, refer to the troubleshooting steps mentioned in Error -732156 When Using Scan Engine and EtherCAT Custom Device document.
