USB communication with SCADA Pack devices can sometimes fail due to restrictions imposed by endpoint protection software. Below are steps to troubleshoot and resolve this issue:

Possible Cause

• DNP Secure Authentication Enabled
  A common reason for this error is that secure authentication is active in the SCADAPack.
• Endpoint Security Restrictions
  Endpoint protection software may block USB communication. Verify with your system administrator.
• Faulty USB Cable
  Try using a different USB cable to rule out hardware issues.

If DNP Secure Authentication is enabled, follow these steps:

1. Check Project Settings
   • Navigate to the project settings and ensure the Secure Authentication Enabled option is selected.

2. Connect via DNP3/TCP

· Use the IP address configured in the SCADAPack device. For this example, the default IP address is used to connect over Ethernet1.

· Establish the connection and write the configuration to the controller.

3. Verify the Security

Ensure that security settings are correctly applied

4. Reconnect Over USB

Change the project settings back to DNP3 USB.

Attempt the USB connection again, the connection should be successful.
