problem.
• Perform a build and download parameters to the I/O pack or module.
• Download firmware and parameters to the I/O pack or module.
• Verify that the Ethernet cables and network switch are operating correctly.
• Verify that the I/O pack configuration (such as Type, HW Form, Bar Code, position) matches the actual hardware.

scan and download to the I/O pack.
